looking great well apart from the burnt sections but wouldn’t even know if they get plucked.
Whats been your temps air and leaf out of curiosity.

Air is 25-26C at the canopy Leaf is no higher than 25 C surprisingly. Finding that with my spacing of the strips that the sweet spot is 8-10 inches for lux as they get closer to the light the intensity is dropping off unless directly inline with the strips.
Edit: Pics and I did have a max of 26.3C

Cheers Homie! Yes I too am looking forward to getting that thread rolling here soon!
Yeah seems the same as i typically average 2 degrees C cooler on the leaves vs air temps as well, something that ive stumbled more into as of late and is a thought i’ve been pondering on is how when we talk or have discussions on temps its typically only of the environment not what the plants are experiencing, so in a situation where say one information source or grower may state there ideal temps is say an arbitrary 24c, what the plant may be experiencing would most likely be completely different when say their hang height and or lighting choice will dictate what the plants experience. As say a grow room temp of 24c if say running LED the plant leaves may be measuring 22c but say the same room same temp under HPS the plant will be experiencing hotter temps than that 24c just cause of the excess IR heat those light sources put out in comparison.
Base of it just kinda makes me question things, and our previous knowledge on stuff.

I totally agree, seems like lots of bro-science out there in the industry and in the hobby gardeners realms alike. I for one will start including more data points for my own reference, I have temp and humidity sensors attached to my extractors at canopy and soil height and it is easy enough to grab some leaf temps even by a picture of displays and the gun.
As to the temps being lower by a degree or two yeah it’s sorta weird stuff… definitely worth more research to see if there isn’t an issue with the way IR is being measured under white spectrum LEDs as you are right it simply counters commonsense even my understanding of physics in part. My only theory is that due to the water content in the plant it is conducting the heat more efficiently than retaining it?!? Always more to learn!

well actually it makes perfect sense in that active transpiration of the plant cools it, but under some sources of light what one may feel is different as led’s don’t have that IR heat component in the same capacity that HPS or the Sun does, but because of that our thoughts on ideal temps may be skewed if we aren’t taking into consideration what the plant is experiencing and comparing that like for like as best we can.
Just food for thought anyways

Super interesting stuff, never thought of transpiration acting as cooling or employing transpiration as a necessity for plant to cool itself in the indoor growing environment, as I said still much to learn 
. As per the IR component that makes a lot of sense.
I guess for me having built and tested the systems to ensure that they regulate around 26-28C year-round keeps me in a good nutrient pickup range - or at least this was the development impetus. Currently having 25-28k Lux on the canopies and maintaining these temps is by no means hurting them in any way yet this too would be considered below “ideal” range in a lot of schools of thought. Any particular gain is hard to isolate down to certain factors as we tend to continue to grow cultivars that grow well for us here in our space so far. Our ideal is having things be as consistent as possible, so far the bridgelux array (that wouldn’t have been possible without your guidance, inspiration and patience it again wouldn’t be possible 
) is putting in the work and I for one am thankful for the experience and reaping the rewards! LED is the now and future kids.
Edit: logical sentences lol

also can always add another driver and strips to your already built array too, as i do agree that 25-28k seems low guess depends on how it yields for you, i know im in the 30-40+k range myself right now in my little spaces with still 5 weeks of growing to go so will be interesting

Yeah TBH I don’t see much change versus old posts from inside the tent and the Mars Hydro so far so I will let it ride, run them low to the canopy for this run, see what if anything needs to change.

Nearly Weekly Weedly Update:
Things are moving along slowly but surely, still stretching. Girls are all stacking, tiny lil preflowers on board everyone in the flower chamber. Been running the array rather close and crisping some tops while flopping them and others daily. I have one Lemon Sour Diesel that hates the flopping, broke another top of her today trying to keep her out of the light 
she is a fragile little lass, likely kill her clones unless the smoke is amazing; looking for hardy not delicate/finicky and otherwise grumpy plants.
I decided that with my plant count rather high and no real room to finish everything I have going I needed some strategy to keep things manageable. I up-potted my 9 seedlings that are a month and a half since being popped now finally today. They spent the entire time in the nursery rack under a humidity dome, restricted to 4’ pots and recently topped. I am hoping to stall these guys out in the Auto Rack for another month along with the 2-month-old bonsais that currently reside in the Auto Rack, the 4 strongest seedlings along with hopefully all 5 bonsais will head into the veg tent 2 weeks before the current run gets cropped. As soon as I axe the 9 in flower currently they will be immediately replaced by the Bonsai/ Ancient Seedling crew and thrown into flower. If this all goes as planned I will have 5 seedlings and 8 clones more than ready to go that will also stall in the Auto Rack until the time is right while humbly learning my lesson about popping backups/more than I need in the next month or so.
Thanks for stopping in!

Terpship transmissions for this week 
Life has kept me on my toes this past week and sadly out of the garden. Outside temperatures have been dipping down quite a bit over the past few weeks, likely not helping the terpship’s nighttime temps likely further compounding their want to stretch. The combination of the stretch and neglect has meant some more burns from plants bouncing off the strips, my bad. Life goes on, only a month or so left and only a few more feet that the lights will be able to come up so we shall see, might scog yet. I am letting the dry pack increase as we are around the 4th week of flower, by shutting flow to the auto pots for a few days the trays and medium dry nearly completely and plants will start to show it. It’s like a kick in the hind bits for the plant, certainly helps with flower production in our setup as the soil in the system is capillary watered meaning it is carrying as much water as the substrate can carry at any time which isn’t really wet or dry - the plants hate it 
Everything in the vertical and in 1gal fabric got a very light feed @ .3 EC Canna Vega and Rhizo just to stave off death, some of these puppies have been starved of pretty much everything in order to slow them down and it shows. The transition from humidity dome for the first month+ of the seedling’s lives to no dome was rather rough on foliage that was in contact with the dome for some of them, again my bad. So some of them got bad haircuts while I contemplate their futures might take some more drastic measures tmr if I can duck work lol.
Really looking forward to spending some serious attention on these creatures very soon some wrangling, some recovery but until then thanks for stopping in!
Edit: Wrote 8th week of flower instead of 4th LoL

Another near-weekly Terpship update 
Another week or so has past and I still have been neglecting these beauties for the most part. They got a light feeding the other day as I noticed a few of them starting to lighten up a touch more than I would like. Today marks the end of 4 weeks(30 days) since the flip, coming into that explosive growth part of the cycle 
. Outside temps have been low and since the tent is dormant for the moment, that end of the space continues to be a few degrees colder at night than anywhere else in the space. This has led to the 3 plants on that end of the space still stretching… Mains are now well above the strips but since everything else is basically done stretching the lights will catch up soon.
In the vertical things are slow but surprisingly still viable. The ones in the fabric pots with handles were popped on Sep 20 so they are approaching 3 months old of pure torture. The ones without handle in black pots were popped Oct 19 and again were neglected, kept in domes too long, and set aside to stall while I make room in the flower chamber. I will be taking the strongest 9 from the vertical and placing them in the tent in the next few weeks for a fast changeover in flower when this current run gets the axe.
Only 7 clones remain some lost due to not taking others culled but this gives me a copy of each of the top performers so far to run at will or mother - still undecided waaaay too many plants on the go for our tiny op.
Plans for the next little while; get my Inkbird sensors mounted and calibrated (I have the sitting in various positions around the lab but no calibration or secured/fixed position so the data hasn’t been particularly consistent whereas I don’t think there is as much variance as I am seeing in the data but only time will tell), Still building and testing systems for my auto projects and still waiting on genetics to arrive for that. Aside from that, I am looking forward to having the time to tend to my plants and catch up on some much needed R&R here over the next couple of weeks. You will also see me around on the forums likely a touch more as time permits as well so be sure to stop by or say hi!
Thanks for stopping today friends, look forward to seeing what you’ve got cooking tonight!

Things are still rolling along in the flower chamber, some are closing nodes others not far behind. Started noticing some early fade on 3 of the more aggressively growing plants a few days back, they really want feed but I had been holding out to try some Tea. So I started brewing about 48 hours ago and they got that at .7 EC today (6 out of 9 plants as the three on the cold side of the space are still dark green and pushing hard even through the lights!). Everyone is still fattening up but it is a touch slower than the last run so far throughout the flowering period with this run.
All of the seedlings in the vertical are happy with their new digs now. Older, previously bound seedlings are hanging on but not sure for how much longer, they need feed badly but their roots are taking up much of the available area in the pot so watering and feedings are needed more frequently, need to make a decision with these pups soon.
Today I mixed up 175L of so of soil and filled up 7-9 pots destined for the veg tent in a few weeks to allow them time to bake. Found some interesting-looking Eggs or mycelium (?!) in the bottom of a sealed bag of super soil, removed it and the surrounding soil before it got mixed but I have no idea what that is. As an added precaution I placed a layer of fresh diatomaceous earth over each pot and set some fresh sticky traps in case these were in fact some sort of creature’s spawn.
But that’ all the excitement for today, I will let everyone know how the tea goes with updates as well as a recipe if it does good things for those that are interested.
All always friends, Thanks for stopping in today!

TerpShip Updates:
Things are still keeping on, down to just over a few weeks left as far as an 8 week flower period that most of these gals are supposed to be. That being said I had a few that are faded completely here in week 6, and others that look like they have another 3 weeks to go. I fed 6 out of 9 plants the Nutrient Tea I had brewed up and a few of the less faded plants showed some N curl but other than that was dirt cheap and seemed to hold them off.
As far as the breeders are concerned Jan 7th is chop day so I was letting them run down the nutrients but I may take 2 a touch earlier and a few a bit later as things look right now. This would mean any that I plan on keeping around for the full term will likely get feed and left until chop with just RO.
I have been chatting with the LED Maestro @Mr.Sparkle over this cycle about the expected output of this build and we had both agreed that we may have underbuilt the light for my intended use and space resulting in roughly 22.5w/sq ft currently. So I bit the bullet today and purchased some additional strips and another driver to beef up the output of the current flowering array. I will take the gen 1 array down, reduce the frame size and load it up with more strips and more juice for the next round. It’s not like they didn’t produce but considering that 22.5w/sq ft and 28-30K lux is generally on the low side of things and my environmental conditions, soil and feed regimes worked rather well with the Mars Hydro TS3000 in half the area, this is the first adjustment to make.
So I decided 10 Bridgelux EB3 Thrive @ 3000k and a Meanwell HLG 340-42AB to beef things up a bit and put more red into the mix as unlike my TS3000 the 4000k strips I am using have very little in the way of red spectrum, which also may be making my lights not as efficient as they could be.
Edit: You may also notice that my de humidifier grow 2 ft, I made a simple expanded res for the direct to drain function on this little unit by drilling a hole in a Sterilite 7.5qt rigid tote, cutting a short length of garden hose and running said hose from the unit into the tote. This expanded my running window from 12 hours to 66 hours until it automatically stops from being full. This is the main input as far as manpower is concerned in our system during flower is emptying the dehumidifier so it meant someone had to drain it every 12 hours so the expanded tote-res was aptly named “The Vacation Machine” by @terpwee-z as it allows us to get away for a few nights without worry in conjunction with the cameras and inkbird sensors throughout.
Anyways other than that, all is well, I hope you all had great holidays and look forward to hearing and seeing what you are all up to! Thanks for stopping in!
Edit: Bridgelux EB3 Thrive was the lights I meant to say

… when did you decide to go with the slims that wasn’t mentioned just note though they are a bit different length wise and a little different on voltage though your driver should be fine and im not sure how they will handle heat wise being half the width im sure they should be fine at nominal though, your now probably gonna have to support them more with them being so thin, if not too late i still recommend the gen 2 normal’s or gens 3 if buying in packs of 20 off futureelectronics as there a bit more than half the price of the slims per strip.
also believe you have the 3500k strips already, not the 4000k but maybe im wrong, part code reads as follows BXEB-L1120Z-35E4000-C-B3 the bolded section denotes the color temp not that 4000 beside it.
