Definitively a good opening this week !
Nice find @anonymous4289 , and as a petrol-head i like the song and the lyrics in bonus ^^
It was annonciating the bonus level i guess
6400K landed just in time. Mounted on the fly. It’s time to unleash the hell during twos weeks 
Thx @HappyTrees23s “Noodles in the pot, happiness in the plot” ^^

This week was a stress-fully nightmare, and i think it’s obvious. They are looking like sh1t.
For Sensi Seeds i’m just in time, for me I have twos weeks late in development. Damn near one month and they still seedlings. You can’t imagine the level of shame i’m feeling.
To heal my ego during this week, i was one more time barely at the point to launch easy strains (Cali Indi or Sensi Star) and to totally screw my timing of the next weeks. I’ve even produced a kind of obsessional paranoia for fungus gnats larvaes, nutes viability, density of the new parabolic setup, soil balance … everything was acting like a fcking ghost haunting my mind. Holly fck, i was not prepared for that.
Despite the appearances, the situation is now under control (since yesterday only), and i can relax a bit and apply a dose of reasonable LIFTA for the next week. They are on the railroad now.
The good points :
- the expression of phenotypes are very characterized, immature chemotypes set too : scents are allready clear and loud, and variations accurate.
- the root production is over the normal stats of the strain, by far. I was forced to apply a pretty hard hydric stress to stop them to wrap the soil carrot, and to densify the core. I’ve pushed too far, but i don’t regret. I’m not planning to use vegetal mass booster with them, so i compensate the most i can to have the full expression of yield of each female.
- the BB have the tendance to herm in the final stage of flowering time, with all this suffering and wounds … if i’ve a non binary specimen (lol), i think i will see it fast after one month of 12/12.
I knew since a while that the BB is a diva but I’ve underestimated the side effects of a spectrum restricted to twos bands ^^ She’s very not a permissive strain. But i still love this underrated strain.
From now you can pass, just details of I’ve already said.
My love affair is doing everything to mesmerize me. I guess it’s a trap.
Too musky to be in the range i’m seeking, and i think now that it’s a strange male. At least it’s the new side of my doubts.
It was the first specimen to get back on the track, way earlier than others by far. Root mass is just insane and she eat and drink like crazy for its shape.
More beautiful and balanced than ever, but not in the range (for now) i need to start the IBL. I guess she have a slot for the Jack Herer zombie if they haven’t the same sex. Can be a fabulous duo.
This specimen is the only one to have a decent resistance and reactivity to intensive care. It push me to think that i will need sh1t ton of seeds to improve the vigor of this line without too much compromise on the yield/taste that characterize the BB.
The Zombie Jack is back for the show.
After nine generations and a bunch of seedlings under the belt, i already recognize what i’m seeing. And i prey all gods of ganja that it’s a male. It’s a very great starting block to make a “zombie blend” poly-hybrid. Unexpected blessing, at the point that i will delay the 12/12 switch of the whole tent just for “him” (fingers crossed).
Intensive care of this week : the usual little trick of the week ^^
I pass on juggling with nutes, it’s too specialized on the strain. But I’ve one trick when i’m in the sh1t to the neck and that i have to boost the plant ASAP for yesterday, in keeping them alive :
Shake the sprayer as hell before each single use, try to fill it only half to optimize the shake.
Spray generously both faces. And stop watering/feeding the soil totally during the whole treatment.
The frequency is up to you, really. If you want pass your day to spray the plants between twos drying state, enjoy. If you’re not in the “my soil have to be humus” club, let dry it far while you’re spraying the plants all day. It will boost the hydrogen exchange when the situation is back on the track, chess move.
Using GHE Micro at this dose (ONLY) is important. I’m using the hardwater version because i finish the bottle and that my tap water is pretty high grade (without RO), use the right one in accordance with your situation.
The H&G Magic Green work pretty well also, but it’s more to boost the photosynthesis in a short duration. The effects are vanishing within 48 hours when you stop it.
The GHE-tricks is maybe less visually impressive but you help the plant in depth to get back in the track.
A little root porn of the most wounded and trashed specimen of the gang, for the posterity :
I’ve stopped the “plushy wrapping” with drying cycle, the core is very firm in all the length now. I’m proud of that at least ^^
The “wrap” is supposed to be at the “rat tail” stage after a week, but the vigor was not at the rendez vous for that. Next week i hope. It’s very important for me, specifically for a yielder, to reach this point before the last transplant. From 2 liters → 10 liters (X5).
Can’t wait next week, i will have something decent to show. Finally

I think Red light helps plants more likely to turn out male. And less nitrogen.
That’s is if you believe what some say and they decide their sex within 4 weeks from seed.
Not sure what I believe, havnt looked into cannabis biology much. I do know that last year I was using Blue lights to form more Females for my outdoor garden, and only 5 of the 80+ I had started turned out male.
Also less humidity and higher temps for males.
Opposite for female development…as far as I’ve read online. A few studies tested it out too, and did say they believe it works.
But again. I don’t know the science of seeds or anything about cannabis sex development.
If it were me I would try it tho.

Thx buddy ;o)
Most of what i will say is on the documents that are presented in this thread. But the reading is pretty arid, let me take a straight shortcut.
The “practical state of science” today on this subject is at one point that can’t be hardly debated.
And it’s imho well synthesized by one specific professional offer declined today in a large number of services available :
It’s just one example on thousands. And this is not a scam but a reality.
Serious company like Canna offer this service here in EU, too. They don’t play with their reputation.
From this point, i’m sure you have understood the drastic conclusion. But what you read on it is not specially wrong either. But everybody here don’t want to preserve a genetic that can change sex with epigenetic factors ^^ Yeah, the subject is shitty and i’m glad to throw it right here, losted in the flow of OG

They are back in the track, finally. And i’m still mad at myself for the 2100K experimentation, even for the load of datas i got and the drastic phenotype’s answers. Ambivalent. But the plants and me are happy, that’s the most important after all.
The cure of Humic acid have created the necessary buffer in soil to maintain a good carbon rate to follow the boost, and the Fulvic acid have made the fat food more digestible. I’ve used a 50%/50% ratio during two weeks and it saved my ass. One more time.
For Sensi Seeds, i’m synchro but for me … dang. One month of grow seriously ? WTF Fuel, you have to wash this ultimate humiliation with a stellar flowering stage !
I’ve stupid hopes, but i don’t expect to have sex declarations until next Sunday. I think that i’m on the way to 7 weeks vegetative stage. It make me sick, it will kill my grammer/day ratio if i don’t produce massive buds. Damned. I’m so humiliated lol Can wait the round of California Indica to wash my honor.
From now you can pass, just details and notes.
Recycling the bad in good : Roots and hormons.
Unfortunately, the good results cannot be written in the marble here. And they are directly linked with the segregated spectrum of light they got. I can finally be 100% sure on it now, considering this well known lady.
The strain is helping, building roots is her thing. But the root mass density and the core is out of charts, going crazy on it between update 8 and 15 is paying back over my expectations. I can squeeze the clods in my hands like sponges. It’s not impressive with coco coir but doing that with the root in this soil amaze me. It’s not even sieved like i usually do, but a cheap supermarket rich soil straight from the bag. The transplant will be a pleasure to follow. Can’t wait the harvest to watch inside what i’m feeling with hands.
But the extreme side is unexpected : the weight. It totally fucked the sensation of my hands to drive the dry cycles, the weight is just insane. To keep them happy, i’ve to keep the pots heavy like the hell and to reduce the dry cycles to an “overwatered” weight. Very disturbing, and i can’t wait to see if it will transfer to buds of course ^^
It push me to develop more a previous theory : forcing clones in veg under 2100K in 1 liter pot, going crazy on root booster and SOG them. I’ve validate it with the buds of this round, only pushed with PK and nothing else.
On the hormonal development, it already stink when i open the tent and they are not yet at the 5th node. Considering that for me they have twos weeks late, it’s interesting. The musk is strong and deep in the nose, but the chemotype’s variations are already active and it’s not something that happens until the pre-flowers stage usually. The 2100K have triggered and answer, and i think that’s why the phenotypes are already so characterized. The torture don’t explain fully the expressions.
About Sensi Seeds : I’m shared
I get back the Big Bud i’ve well known, there is no doubt for now on it. Even in the extremes, i know this car and i can go full throttle without kissing the death.
But … the old motherplants used appear to have been a bit too much kept and considered like a “storage” and not as a genetic material. I’m a bit disappointed.
That’s my love affair, the BB#1. Definitively on the NLish side of the force, and not compliant with the goal of the reproduction of the F2. I will drive this line totally with a selection based on the Salmon Creek Big Bud structure, so mostly sativa-ish, stretchy, the fattest i can and over 60 days of flowering time. Buying the BB to don’t make it a powerfully “yielder” is a bit stupid imho. But the gods of ganja took another decision :
She/he is variegated 
And not the only one, barely half of the specimens are triggered.
This is Siamese from the double ovary seed, a variegation was expected and from the seeds germinated the plant was segregated from the program. But damn Sensi, get back in the track with your MP. On a ten bag of regs to have so much variegation before the sex declaration is a bit stressfull and reduce drastically the faces of the dices rolled. Renew and care about your fckng motherplant damned hell, your seeds are expensive : offer the standard of quality correlated with this fact.
Can be tricky to see on a photo, but it’s not a variegation. It’s just the first time since two decade that i see a “neon light burn”. It’s the most obvious on this specimen, but they all have it at different degree.
lo rompimos todo hombre con la patente canadiense, esto realmente funciona jajaja
Some news from the Zombified JH
Let’s say this one was naturally FIMed, so long to develop but nothing surprising. OId lady only pushed for potency at any price, vigor included. I’m in the sh1t in term of synchro, i’m supposed to couple it with a Big Bud to start the Zombie line. I’ve not to push it far in veg, but if it’s a female i want enough seeds to have fun with it. Half-stress.
Another private joke/dedicace for the king of BBQ : done in 5 minutes top chrono ^^
I’m blaming them for the variegation, but the ratio is pretty neat for a F1 of this kind → 3:4:3
Subgroup A : NLish as fck
Subgroup B : Hybrids
Subgroup C : the SCBB style ^^
That’s all for this week, keep the vibes high !

For those who don’t know the brand :
I discovered this around 2005, i was coming directly from Atami (Bcuzz line). Still today the line of nutrients i’ve used the more, at every scale possible.
The two flagships of the brand are the Root Excelurator and the Top Shooter. And for the last one, I’ve found a kind of trick to express radically the yield in most of strains.
And that’s the problem, considering the interest of @KETAMINE_GRENADE i’ve started to make a kind of schedule that quickly became useless in considering different types of scenarios.
I can write a schedule for a 45 days Kush, but the timing and the dosages become totally shitty for a “Dutched Haze” like the Silver Haze, the Jack Herer or even the NL#5xHaze. If i write it for a skunk, it can’t be compatible with anything else. Etc …
So the best way is to share it as it’s used : without any schedule but the faculty of adaptation to the strain. And in fact, it’s only in this case that it become barely universal. Not with week’s numbers that mean nothing from one strain to another one.
On timings alone, it’s pretty universal and i’m writing it also for a couple of friends not using HG nutes but interested on how i can inflate the plants without destroying the quality with hard nutrients.
Let’s dance now ^^
To best use the potential of the Top Shooter, you have to prepare the plants to furnish it. Watch closely the plants and the day they start to really stretch, start the Roots Excelurator.
Root mass full throttle = TS used at maximum potential. Needless to say that if the medium is not entirely colonized with sturdy root in a dense configuration, any flo booster is just a waste of money.
Also the stretch is the most productive period for roots in the whole lifespan of this plant. Plants dig really hard during this frame of time, and it’s why i generally transplant in the definitive pot just before to switch to 12/12.
Rightly boosted during this time, the roots transform an uncontrolled stretch in a “good stretch” for the yield. It mean thick secondaries ready to fire. It limit also the height on most sativa-ish strains, very effiscient on the Jack Herer.
When the trunk stop to act like a spring, the roots stop to colonize and they start to densify. The production of hairy roots for cannabinoids start. The plant enter in a week of “holiday”, because tired to have reached its definitive shape.
Giving a little boost in micro permit to prepare the war that is coming and to don’t lose totally this week, it permit also to keep the root booster at Max without tiring more the plant. For more weight but also important for the final quality in term of potency.
The pivot point of the whole trick is here. And it’s not specially natural to consider at first glance, you cut everything but a finishing product.
This idea come with a pure africaan then later with the californian COB cut, the stretch of the stems supporting directly the flowers was very obvious during this period and i searched how to jugulate it.
Applying the Top shooter at this point permit to chock the plant and to prevent the stretch of the stems directly supporting the flowers : the one you trimming to individualize each bud, but also the central stem of the buds themselves.
This treatment permit to push harder the Top Shooter later, and to get more compact and fat buds. Even in aerated sativas.
Don’t worry for the trichomes, most of them are immatures at this stage and are “fake ones”, with atrophied bulbs or no bulbs at all. The good snow is coming later.
This is the soft way, for delicate palates (like mine), to cover the plant with trichomes before unleashing the hell with yield. Or the hard way.
Unleashing the hell in yield, in twos styles.
The hard way is unleashing the hell because you have the right hungry strain for that. You will not transform the genetic with nutrients, a greedy fast saturated plant is just not made to be a monster.
MAX+ mean off chart, over 100%. The advantage : drying process stress less and pretty fast, curing too. Disadvantage : the more extrem, the more “dry smoke” you get. At high dose, you can transform an expansive wet Kush in a dry and dense COB hit. Be warned, don’t max all strains.
1:400 is the ratio of concentration of humic and fulvic acid of AN. I’m using actually a cheap 1:1000 product with the same rate (at factory dosages ofc).
The end of the rush, before you do what you’re using to do : flushing, not flushing, half flushing, whatever.
After this program, don’t use zym for the final stage if you’re flushing but more a fulvic dilution. Rince the medium with that.
I personally prefer to create strategic carencies before and to flush depending on the round, i’m very-very picky on terpens quality and harvest my sinse before it become fully amber for max potency. It don’t hit much the yield VS full throttle, no more than 15% in general with all types of strains.
See you tomorow for the next update. Still boring, no buds. And no sex, the 5th node is just showing.

For Sensi Seeds, i’m barely synchro. For me I’ve two weeks in the ass. Damned.
“Hormonally” i’m very happy and i passed the week to start the notations on everything. It keep me busy. Even the scent are now very characterized and the phenotypes are expressing fully.
But the bad start have created a late and a delay between the aerial side and the underground side. The root mass is ready to be transplanted since more than a good week, they have all insane block of roots hard like rocks. They are eating 5L/1.3 gal per day, sometimes i’ve to split the watering during the day to don’t let them become too thirsty within 6 hours. They are “forced”(horticultural meaning) as fuck, can’t wait to flower this.
I know and i feel that they are waiting like compressed springs more room for the roots to grow like crazy, but they have to do the peep show before.
I’m waiting the pre-flowers to transplant them in 10L/2.6 gal. I’m starting to see microscopic shoots aside the base of secondaries, good sign, and i think that the next week will give some declarations.
They are eating like ogres too, not expected. I’ve pushed the humic/fulvic at max to catalyze the dose of All-in-One but it start to don’t be enough. Next week I’ve to lower the acids and to push the base to 75% of the maximal dose (1.5ml/L). I’m supposed to be at 100% at the middle of the flowering stage.
I think they will go off chart fast.
You can zap from here.
Zombie Jack : ready to fire
I was waiting the colonization of the pot to prune it a bit and help it to get a shape. Done in one week without any root booster, i’m happy. It’s like reveg clones, when the phillotaxy is a bit disturbed to cut the funk help to restart the grow at one point if the roots are ready.
I think it will be synchro with the prude Big Bud, it will be the advantage of this extra period of veg. I will not transplant it before the 12/12 switch.
My disappointing love affair
Still mad at Sensi for the variegation. Even light, it break a bit the potential of use of this specimen.
Depend on the shape and the sex of the Jack, maybe i will roll the dice with it for the zombie F1.
Overall
This one is nice also but unselected at this point, it’s already hard to stay focused and to respect the minimalist approach. Each day that i’m making notations, i’ve to remember that i’m launching a repro totally devoted to preserve a yielder that i want the closer possible to the SCBB performances and shape. Not a taste agent or anything not fully dedicated to this goal.
Scents start to be mouthwatering, but I’ve to keep the head on the shoulders. At first I’ve to reduce drastically the water needs, to improve the vigor and to push the yield at max potential.
At this point i’m anxious to be lured by a couple of short specimens, in the “hybrid” group, with great potential of stretch. I need to resist and to avoid to create parallel lines, and to go straight to the F3/F4 segregation. Psychological bias, i already know what i have under the nose in term of balance.
I’m forced to say that the line is no longer stable like before, and that the motherplants are on the end of the road. Still worth the pain for now, the critical traits are responding.

They are under 2x18W T8 neons since the night of Wednesday/Thursday, H24 regime with insane RH (80%), with stagnant warm air … and they are happy as fck. Bitch to the nails.
The underlying reasons is my usual madness, the space is under construction. Again :
I will try to make a big post to show details, i have to :
- for the prince of smoked ribs with texan dust, and his chimney
- for the citizen of the temple of Jah swearing only by the bat guano, covid panic or not ^^
- for the only one farmer in the alps covering the ground of his chicken coop with ganja fan leaves
- for the only car exhaust manufacturer in europe responsible for the blueprint of this crazy triple-CFL-reflector that I love as hell
The craziness start with some considerations on air pressure, both in the 4x4 but also in what was planned to be the “porn room” to pollinate the females.
For this last consideration, after one test the negative pressure was so insane that it was not possible to keep a male alive inside twos or three weeks.
BB#5 is really sexing since Wednesday and is the only one. I’ve a bad feeling about this one, i suspect an herm. One of the nicest combo of notations, except the scents. Off course. But not in the range of shapes i’m hunting, by chance.
All the others have reached the final hormonal stage, they are sexing at usual speed. I dislike my late in grow generated by the 2100K experiment, they are too advanced to stay in 2 liters / 0.5 gal which limit a lot their “wingspan”. No sign, but i know they are starting to suffer from it.
To be continued …

The two pics are from the same day, it’s a fcking celebration for me. No more vegging on my grow desk under very low density and saturated atmosphere. It’s sad in a way to see that they don’t give a damn fuck, except a bit of elongation.
I’ve finished the final version of the updated space, after a total of 5 prototypes. It’s Armageddon around the tent. Big mess, tools everywhere, dust and all … it make me crazy.
To stay in the grow log, they are in plain declaration period but surprisingly they are not in hurry. Hormonal balances are full throttle for all, the phenotypes are individually very characterized. I’ve a dense week to read them in details. Well it’s a bit more complicated than that, like usually.
First factor : Partially due to the chaos of this past week and half, they are not in hurry to make the peep show. If I transplant the declared females now in 10 liters / 2.6 gallons, it will give them a comparative advantage and it will blur my overall sight. They are all ready to explode, the day i’m transplanting they will dominate as fast as they can.
Difficult choice : waiting the declaration in normal conditions (no more relocation, the tent can be continued to be upgraded while in production) or switching the 12/12 in twos liters when i can. I don’t like the second choice because this strain is a yielder and will be kept for that. And a yielder switched in 12/12 before the transplant mean wasted grams, not strategic to see the full potential. But not dangerous for the notations either, because they will all live a synchronized limitation. Hard choice.
Second factor : Due to the new setup, i can’t switch them in 12/12 until I’ve finished to build the three passive intake boxes. Depend on surprises found while building it, it can take one day or a week.
Time will speak, and i’m now in good conditions for observations. Plus, they are back in decent light density and it will speed up a bit the declarations.
To do list :
- to build the three intakes before switching the lights in 12/12 @ 2100K
- to mount the males/porn space with individual exhaust, used also to extract the smoke of my blunts
- “tent tunning” : a bunch of patchs, zip reinforcement, tubular-structure-modding to prepare for the blumat system … basically i will mod one tent with another one.
The posts on the upgrade will be damned long but i took plenty of photos … i will split the whole process by subject. I will try to be enough clear and technical to share it with all, not only the ones that was directly or indirectly involved in this madness. The changes are not obvious at first glance.
See you later, i’m a wreck right now

I’ve barely developed a Stockholm syndrome with these Big Bud, we lived a journey together and they handled a bunch of crazy ideas during the whole ride. But it’s finally the time, tomorrow i mount the 2100K bulbs in the reflector and I switch them in 12/12.
I’m surprised, the declaration are here but are staying microscopic.The thickness of a needle. No rush. I was expecting to have a more clear and definitive sight during this week, but no. Most are tagged females, only one male spotted, the choice of pairing to start the IBL will be complicated i think.
Considering their very extended vegetative stage, i’m expecting a stretch from outta space. I’m ready for it at least. I can’t wait to transplant the females in the next pot too.
On the grow space, today is the true end of a very long travel. A shit ton of blueprints, a shit ton of prototypes of everything, hands have more wounds than i can count … but the results are here, even if it mean nothing in the photo :
The beast is done. I’ve some finitions and modding to do but that can be done in peace. The mission is accomplished by far, i got the graal.
The porn space is ready too, it was actually the main reason before I fall in a strange exploration of a bunch of parameters.
Most of the photos are shitty, i’m a pretty bad war reporter. But enough clear to show the journey in all its steps.
It doesn’t look like a decent grow space but more like a random construction site from the third world. It make me crazy, I hate to grow in the mess. I’ve a ton of cleaning to do next week, before the flowers come. Ton of dust and all.
I’ve to build the “grow table” tomorrow and i’m done with the tools and the big mess. Just light finitions.
But damn, i was forced to rebuild everything from scratch it was a madness, and a big awareness step too on parameters i wasn’t considering the right way. The whole electric circuit is re-wired too … massive reform.
See you later, shared between a real grow log now and dedicated posts explaining in details my last craziness in date.

Today i’ve enjoyed a decent grow space for the first time but let’s share some awareness about leaves by a radical example.
The whole room was finally cleaned. Washed, brushed, “vacuum-cleaner-ed” everywhere, then the tent, the lamps and the reflectors. 12/12 time, no more margin on dust.
And one time everything was clean, it was the time for the plants to get their shower. They don’t have seen a sprayer since a month and it’s a good opportunity to show what’s the point to clean your leaves.
So that’s the setup in this corner. It’s the “dirty space”, but in center you can see a simple trick i was using when i was making fems and that i kept for everything : simple, secure, efficient and easy to wash.
On the right, it’s to wash the top of the medium just in watering with good drain flow. I’ve just waited a dry cycle to can launch the whole operation. Cannabis don’t like to be sprayed with feets already well wet.
And now what I collect from all the plants shown :
It’s not that extreme usually, maybe only 25% of this epic photo for a whole group of a dozen plants, but the more they are tall … the bigger the dust harvest.
Twos big wash during veg time (the last just after the transplant), and one after a month of flowering time can move a lot of dust. When they are very dirty like that (by dust or pollen), i use only plain water but for light showers i use a light nutes solution and i water the next day.

Today i’ve started to “mod” the tent a bit, let’s call this finitions after the big modifications already made (will be posted soon enough). Nothing fancy, but some annoying details to fix.
First thing, the zip and a problem we are numerous to encounter i’m sure. Previously i was an unconditional customer of gorilla’s tents, but even on these ones i was worried by the zip after a time. For the defense of the brand, under insane intensive use.
First thing to do : a bit of sewing. Thick needle, doubled thread.
In a Chanel workshop, i will be fired in the minute 
I’ve added a line of cyanolite /cyanoacrilate on the interior, this stuff work very well with this kind of material. Heating well while drying and making a true soldering.
Then the secondary problem, light leak on the bottom and with time a loose flap. No bad joke intended, i swear.
I’ve broken my mind and my hands to generate a pure darkness in the tent for the plant’s night, it’s silly to let it like that.
So same technic but in the reverse. I use the glue to place the patch, then sewing scavenged scratchs.
And i’m happy.
Next step is to get rid of all cinching duct ports and to patch them too, but i’ve to wait the timer after the dinner. One at a time i think, i’ve 7 to patch ^^
It’s not only because i hate to wash them and that they are not so hermetic, but also for a future improvement on the tubular structure. Another strange idea that will end in prototyping something ^^
On the plant’s side, i’m on the go for a second shower when they are in dry cycle. They was damn dirty with all the stuff done around. At least they loved the first pass.
This time i think that i will add a pinch of PK to the foliar wash to stimulate them, i’ve three specimens not declared (in don’t including the zombie jack) and they are the most indica of the pack.
A little stress is coming, for now i’ve only one male and 6 females. He have all parameters researched at max, but i dislike this unique male. Too fast hormonally. I’ve one another potential on sight, i cross my finger as hell until the clear declaration of this specimen. A bit less vigorous but the secondaries and their density are fire.

Actually i’m crushing my head since three days to find a right way to present the rebuilding in details. Behind the humble apparences, there is a lot of calculations and concepts. I don’t want to make it too tailored for “private winks”, but also not to fall too much in boring technical aspects and maths. It’s all about airflow, not rocket science either. The angle i took is a bit strange but not specially off road also. I think i will draw a bunch of synthesis on the wacom and deal with it, most of documents i’ve used come from an unique source that is recognized on a national level. And it’s american ^^
Here we go again, most of the plants were enough dry to get their second shower and to become enough clean for my tastes.
This time i’ve used Super PK on foliar, to stimulate them a bit. I’m hoping that they will not insult me too much. I’ve dosed it at 3.5%, i was kind. I hate to switch the lamps before transplanting, i loose grammers everyday.
While i was washing the plants, twos news specimens was declared since yesterday. Two more females, for a total of 7.
And one additional male confirmed (thx Jah), the one on the left, the #10. So the #5 on the right is living his last week, fortunately. I don’t like him. Well, i don’t like him for this specific round.
I hate so much these things, i’m very happy to get rid of them now. 6 remaining damn.

Intro
It’s all about sharing in details the cascading reasons that pushed me to rebuild entirely the space, it mostly concern the airflow optimization under unexpected parameters. I will split it in different dedicated chapters because it’s long to write it in thinking about four friends with different interests + the random fools and OGers finding these posts, at a time.
As an excuse i will give what i’m considering as a golden reference to all fools interested to dig the question for their own adaptation. I’ve used it to the bone as a guide : it’s the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Their docs are numerous and well-written, the potential of use is enormous for those that want to spend time on it.
Most of their production is a paying service as a subscription per year (over 200). But … some of their “hankbooks” from 2006 to 2019 can be coughing somewhere that has a logo with a boat.
Also a very inspiring practical video for empiric guys that want to test one million configuration per hour to find the best one.
It gave me also a lead to use the empiric method of the automotive designers for understanding what the fuck was happening in my tent.
Now the story, where the evil is in each fcking details actually. But i don’t regret the ride with backward.
The context : the previous flawed space
The goal during the building was to be the more dense possible, to make the more space possible around. Also very easy and fast to maintain/wash, with specific sense of the movement of things barely like a professional kitchen (dirty space, washing space, clean space, cooking space …).
Everything was good on the final blueprint, even the strange closet built with my experience on various spaces. I’ve just tryed to veg the Big Bud with a narrowed yellow/orange/red spectrum, in the hope to never switch my bulbs. Of course it was a bad idea with the neon tech, but at least i’ve the psychological proof of it now. Done.
The firestarter of a lot of cascading problems
After the first month of 18/6 and seeing the Big Bud not specially in hurry to show their sex, i’ve planned a switch to the 12/12 regime. Then, because i’m mostly addicted to seeds, the pollination of the first inbred generation + the zombie bonus.
I realized that i was so much focused on the plants (and happy of this fact), that i forgot to test the pollination space. And I’ve done it first with a young eucalyptus clone (i love it) then with a young plant of peony (my wife love it). Both vanished very fast, with excellent and sturdy genetic.
Then at this point i’m entering in panic mode.
This is the “lung closet”, planned also as a “pollination space”. A “porn room” in my slang.
It look like shit but the blueprints were fire and this is a lot of work overall, this space was fully hermetic and jointed/insulated. The torque in the tent was amazing and this, in a very low level of decibels.
But any plant inside was doomed to die, it was not at a vacuum state but the negative pressure was enough strong to don’t let plants breathe. Literally.
It was written from here, I’ve to rebuild something ASAP to can launch the flowering stage. Used to build porn room with pretty much high negative pressure, i took my lesson to have pushed too far and I’ve started to analyze more my overall airflow. To find a solution but also to check if I’ve not made another bullshit.
The secondary problem
And it was the case ^^ I pass on the wool thread aerodynamic test, but the tent wasn’t working as it was supposed to work. Even with certified maths.
Second panic attack : The Big Bud is (very) prone to mold in late stage of flowering, and is also a five stars hostel with mildew. Add the Critical Mass, tested and approved too.
And it’s where is really starting my journey in the real understanding of what is the static pressure. In being screwed with plants i can’t flower, until I’ve build something decent to pollinate them and also to flower them with high constraints on airflow. And the inherent constraints to grow fully with neon, from start to end.
Add to this equation that i’m stubborn and i don’t want a permanent (well,sized) active intake, no de-humidifier, no AC, and nothing more than the lamps and the plants inside the tent … well nothing more than a single RVK running 24 hours a day for this tent.
At this point i’m trying many things, not so to find a solution but to understand the problem and the leverages that are specific to my setup. And it’s when i’m opening for the first time since i’m using tents, the horizontal vents. All of them.
A magic happens then and i see the leafs of my plants dancing like I’ve placed a fan inside. Never saw that before with this kind of negative pressure.
Discovering a bonus function of something absolutely not planned for it
In viewing all these wool threads taped everywhere doing something i’m not understanding while i’m closing the horizontal vents, and opening them … i think about my reflector. And i tape it with wool too ^^
Now consider this :
And that the diameter cover almost the whole tent surface of the ground.
It’s when i finally got the “eureka” thing and that i understand that it’s useless to fight with parameters that depend on one big factor : the bad management of the static pressure.
Conclusion of this step :
- I’ve to rebuild everything with the good priority in mind : the static pressure over the speed of airflow
- In using the horizontal vents instead these awful duct ports i hate since ever, i can get a nice airflow that is venting the plants like a big fan and without a crazy negative pressure for them. And without any fan. And from the bottom.
- It was so useful many times but i’ve now to reform what i’ve learned from my indoor mentor : the old way to consider the airflow like a liquid. I’ve to consider the airflow more like the gas feeding the engine of a car : phenomenons of dilatation/compression, stratification of dense cold air and hot air, vapor restricting the compression etc …
- The tri-CFL parabolic reflector changed the rules of the game and break the standard calculations, I’ve to adapt fully to the wool lesson. Not adapting what is supposed to happens on the paper, on something that can’t happens ^^
It was for the context, the datas and to please the fantastic four on the details. Spoiler : next, it’s not an happy ending at all. But a long nightmare among 5 prototypes that failed miserably. Reforming habits and way of thinking is not easy. Don’t be afraid I will show only the 5th, because it was not that bad in fact.
See you later in the next chapter, more in depth on Static Pressure (SP) with a few draws.
