School me on octopots!

@Papalag pretty much covered it. He is correct, did not care for the 3 gallon version, grow in the 6 gallon exclusively.

I run inert soil in the sleeve, that way I control what the plant gets fed. Every fill up has nutes in it like Papa says.

We start with rooted clones from Dixie cups, One 1/2 gallon top water is all they need/get, then just bottom wicking.

A friend of ours uses his own living soil in them, and kills it. It takes A WHILE to make the soil, a while before it is ready to be used. I prefer the inert soil mixes, and then feed through the rez. IF you go los soil, go to my latest thread and his version and how to make it is in there.

Feed is at low PPM because it is constant, i never ph my water, do not even own a working PH or PPM meter anymore.

6 gallon rez is plenty in veg, fill up once every 5-7 days in veg. Big plants in full flower can suck 3-5 gallons per day, so larger plants in flower need rez fills every 1-2 days. You can use simple gravity based aux rez/controller’s to auto fill them, I have not had the need, takes me 5 minutes to fill 4 octopots from a 30 gallon can with a pump in it.

My last run brought down about 32.6 Z’s from 4 plants, but they were pretty large and needed support to keep from breaking stalks.

I 100% reco them, and they have no downsides other than physical size, 18 x 18 is correct. I place 4 under a single Gavita DE 750 HPS and cover 16 sq feet with it set at 825 watts when in late flower.

I know of no one who tried them and did not like them. I know I shall not stop using them .

Thanks to everyone who gave input. @Jetdro can you tell me how tall the 6 gallon octopots are in total. From the floor to the top of the sleeve when sitting on the rez.

About 22 inches I think, lights off, will check tomorrow for exact, I did post it somewhere in my thread

Thanks. I like reading threads so i guess i will start scouring through it. Whats the thread called?

Just pull the trigger on them, you will not regret it, figure out how to set them when you get 'em.
Honestly it could not b much easier, and Chris, the owner, pretty much lays it all out correctly.

On my 8th-10th run or more, not a failure yet, everything still fits and is in working order. My sleeves are getting a bit ragged, but still work, so until they split or leak soil, I will just keep using them.

@Jetdro
What kind of inert soil do you use? The youtube video says sunshine#4 is already perfectly balanced with perlite and such.

2 Likes

Hay tappy what ever you use you must add 25 % more perlite for the drainage ( as per instructions on there site )

If you use something with no fertilizer in it it seems to be best (IMHO) so you can control the feed

I blend 50/50 mix pro mix bx and happy frog
Then a mix of perlite and vermiculite total about 25 % of the soil volume

Peace

Definitely thinking of making a small, small scale version of this system. I dont have too much space, so the 3 gallon would probably max me out…the 6 gallon isn’t even an option.
200 watt cobs here.

1/4 Sunshine Number 4, 1/4 Roots Organic original, 1/4 worm castings, 1/4 perlite. Mix well, then add another 15 % or so perlite to “wick” well.

Can use straight Sunshine 4 with added perlite, or Promix BX same deal, any of the quality inert mixes will work .

One thing about these no more guessing on watering
Did I over water or underwater they just drink all the time

The best way to grow for me

I do like flood and drain to waste, this is less work

@Jetdro. School me please! I though an inert medium meant no available nutrients. And, ive always thought that worm castings were abundant in organic nutrients. Please explain! By the way, Im ordering A 6 pack of the 6 gallon octos tommorow because of your grow journals on here and i have not heard anyone have a bad thing to say about the method.

You are correct it does mean exactly that. The worm castings are food, you are correct, and abundant . They are slow acting, and get used up, there is none of it left in my original mix anymore, after 8 or 10 runs in the same soil.

When I make the mix (usually lasts me 2 years or so) I do use it, and more for it’s ability to “bind” loose soil than anything else. I use it as mixing glue, if that makes sense. My other 3 parts are very loose and mostly coarse, so the “wet” and crumbly and heaviness of the worm dirt help it to set in the big loose sleeves. I actually use less than 25 % of it, prolly closer t 12 -15 %

Your not gonna hear a bad word about them. Chris created these For THIS purpose, they are his work, not a cobbled up set of plastics. The design is simple/elegant and just flat ass works EXACTLY as he says it does. Not gonna leak, not gonna crack, not gonna fall apart with proper use.

I use mostly inert because Im an idiot. I need it simple. By doing inert(or close to it) I am able to FEED EVERY WATER, which means I do not need to remember a schedule, or follow one. Simple. Needs to be filled, 1 teaspoon per gallon of whatever nute I choose (flower/veg) every time, that’s it ! A Space Monkey could do it.

Yes I tweak lil things here and there, vary the NPK ratios depending upon week of flower, adjust the rez level depending upon cycle, and a few lil other things, all things you can figure out as you go.

I KNOW these will kick ass with 100 % organic , inert soils(or close to it like mine) , LOS soils, and might even work straight COCO!! The way it works needs to be understood. When you get it, and it sinks in, then you get a better understanding of how plants thrive in nature. It mimic mother nature, with a perfect setup .

Both @Papalag and I like the “dead” soil, so we can feed them the way WE WANT TO! Yes, they decide when and how much and how often, but with a dead soil, I decide WHAT. That is all the control I need, plant likes it better too!

So, make my mix if your stateside. Not gonna get all into it, but there are reasons why I mix the Sunshine # 4
with the Roots Organic Original. It works well I would have to say, lol.

OR…go Papa’s route, BUT , you could not give me Fox Farms ANYTHING, lol…lol…

CAREFUL of any bought soil/mix…HAVE TO spread it out, clean out the trash, it’s in there, and bake it in the sun before mixing and using. In our Texas summer, thats 2 days BAKING in the sun, now in winter, a week or 2 in a kiddie pool in my garage , lol.

The Promix BX with added perlite will be your best bet to do easily. . Add in a 10-15 pound bag of worm casting’s, and mix it all up well, let it stew outside for a week or two, then just run it. Mix the Promix with Roots Organic would kill too!

Have to get the sleeve RIGHT, or mid flower you will have a disaster, lol. Not gonna pull it, and repot the plant in week 4 of flower, so what you set up is what you get.

Click my icon, can see all my threads from there on my profile page. In my threads, and there is only 3 grow journals I believe, you will find everything from MY MIX, making it, to my friends LOS mix and making it, to filling the sleeves, setting water level by week , NPK values I run, and anything else octo related. IF you read those, and sorry they are long, will take 2 hours, but you will know what and when to do it.

Good deal on getting a 6 pack. What are your intentions with them???

I have run them:

16 in an 5 x 8 x 10 under 3 Gavita DE HPS’s

9 under a single Gavita DE on a light mover

and my favorite way, 4 under a single Gavita DE 750 HPS filling up the entire 16 square foot area with BUD!!!

@Jetdro. Thanks for the lengthy and informative reply. A few more questions…Do you ahve to spread out and clean out your promix? Also, what does getting the sleeve right involve? Im definitely gonna get my laptop out(instead of using my phone) and read through your entire journals. My intention with the 6 pack is to use 4 of them in a 4x4 tent. I will have 2 extras. Which i will either hook a local buddy of mine up with for his 3x3 tent, or buy 2 more of them for my veg tent and run a perpetual grow with octos. Again, thanks for taking the time to help out. Thanks to everyone who has taken then time to offer advice.

How do you get rid of all the roots to keep reusing the medium?

I always chuck my hydroton in RDWC but looking to try a simpler type of grow.

3 Likes

YES…especially when new. Lots have bugs, and lots of sticks and trash in them! Even promix!
Not hard to do, can do it inside if you must on a big piece of tarp or plastic I suppose. I like the kiddie pool cause it makes it easy to mix (use 5 gallon buckets…1 bucket of Roots, 1 of SS#4 , 1 of perlite, and a bag of worm castings) it all up, and stir it around with a rake.

The sleeve must be packed tight and STRAIGHT. Any lean to it, you will have issue’s later on with it leaning over.
Sleeve is packed tight, but mix is still loose, if that makes sense.

I use a 5 gallon bucket with the bottom cut out. Slips over empty sleeve, then fill it with the bucket holding it upright and square, in my threads . ONLY WAY to get it really right easily!!

Pour the sleeves out into a kiddie pool, remove large ones, grind other right back into it, they dissolve into the mix in hot sun in a few days time. On my 9th or 10th run doing the same thing.

4x4 or 16 square feet is what I like with my Gavita DE 750(cranks to 825) …50 watts per square foot in these
will kill!!! 4 Octo’s sit under the 4 x 4 perfectly…see my latest thread and can set me set the footprint
