Probably just a bit more. I expect it to gradually increase tbh...lol.

Let me say this. I've done lots of different types of hydro, and grown soil. This is by far the best growth w the least amount of work on my part I have ever seen in almost 10yrs of growing. So I'm already sold. Now I just need to engineer something for vegg that is equally carefree that works well in conjunction w the flower room. Lol
Thanks, my Res is 2.5 gallons, all I ever need to do is a short weekend get away while growing, I think I can increase the res size to maybe 4 gallons with a seperate tank and a gravity hose,, if needed

Been using the Octopots for quite some time now and love them,never had any res issues or bug problems,get a few fungus gnats now and then but they come in the soil and are easy to get rid of,I normally have some spring tails in the res but they are harmless. I get crazy growth and yield with them and don't have to water/feed them every day,in heavy flower I have to fill them every other day but in veg maybe every 5 days or more. I was skeptical at first but they work great for me,I have a pic in one of my threads of two clones,one put into a regular pot and one into the octopot,after about two weeks the octopot plant was like twice the size of the other.
Capt, what soil are you running in your octopots?

I am not top watering, the soil has a gradation from dry to wet, a lot like the ground. I'm also using a loose soil mix with lots of perlite, and since I am not top watering the soil does not get compacted over time, it remains loose, and therefore I think aerated.

I'm not an expert, but as I understand it the plant will develop "water roots" that will tap into the reservoir, and they can handle a lot of water. The res pretty much (but not completely) empties between fillings, so there is an air exchange there. There is also an air gap between the water and the soil, so the soil is not sitting in water, the lower part stays moist equal to the rate it can wick water. All that and an air stone in my res, and I think I'm going to be OK. I'll let you know how it goes.
ur profile is locked

but I invite you to look at a couple of books

that have helped many growers in the past up on my mediafire account

Well played Vostok!
Teaming with microbes is a great read. I have not read teaming with nutrients as of yet. I always try to take or make something from every post I read. Your post is truly a great gift. It has made my morning. My gratitude to you Sir. :clap:
You give me the Happy Face!

Ok people. Im a noob, but i have had people growing around me, with variable success for the past several years and ive read alot around the interwebs etc. Im thinking about putting together a grow cabinet. Been playing around with different ideas when i come onto this, seems fairly easy especially since over/underwatering seems to be the first way of messing up. So id like to ask you if this would be a good idea, with the setup im planning. Cab is 2.5'*5'*8', growing in 2x4, 2 chambers: veg on top, flower below. Thinking flowering using plastic square cases in 2'*2'*1' for res, 4 plants each case and then scroging. Going to use led about 400w of cree or similar for flower. My RH average during the year is about 70 percent already but the cab has room for a dehumidifier, keeping a foot width for utilityspace. Is this feasible? As in amount of plants, humidity. Would like to keep height no more than 5 feet for flowering, less better. How would you do a setup with this system to reach maximum yields with little hassle?

The alternative ive been thinking about is to make up and down cabinet spaces same height 4' and have some full cycle light (3500k) as top light, and with 5000k and 2700k side lighting led cob run softly, many light points being able to switch between warm and cold side lighting. This lighting in each compartment. But the idea of being able to simplify watering with great result seems intriguing.

Also, was going to use organic soil anyway, does that mean i dont have to monitor ph if i water at bottom? Or i do, but only if i wanna use nutes in water?
My pots (2-3 gallon i was thinking) seems very small compared to what everyone are using in this thread. Will they be enough with nutes or can i use nutes in water? Loads of question and i realize some here have only just started with sip.
Thanks

You will never know until you pull the trigger..?

imo/= I'd do 1-2 grows in your new craft before installing the diy? LED.

even under a diy CFL array, is cooler my concern is excess heat?

once you are confident about any excess heat

hang the new light in, at least before flower

the use of autos can be a lot easier on growers the first time round

the 12 week grow is here

good luck

ps ,make ur own thread ...lol

Thank you Vostok for your advice. Still in planning phase, not set to start growing til september/october. Where i am in spain things get really hot in the summer so til i can fork out for ac im limited to about 9months a year. Having a look at link and autoflowers. I was mostly asking reg RH=70 and if theres even a point to try sips as they must add a bit of humidity. Ill look into cooling as well, apart from ventilation.

I dunno, being a newbie, i tend to read and read and read and come up with stuff i want to do without thinking how complex it gets in the end. Will make my thread once i get the wood for the cabinet. Already sure of what dimebsions can fit. Thanks again

My pheno hunter adaptation of a octopot is done. I only cut two holes for now because I only have two plants to run this time,I'll cut the other two holes when I need them.
Looks good, I hope you'll show us the whole set up when it has the plants in it. I'm also looking forward to hear how your search goes. Looking back I can see you really influenced me, everything from seeing how well your SIP did to how well your Gorilla Glue did -- I ended out growing that last inside grow and I have one I'm going to do outdoor this summer.

I'm setting up my outdoor SIPs. I'm a little concerned, after doing my unintentional air stone vs no air stone test, that my outside res's won't have any forced air movement. A lot of the pre-manufactured SIPs (EarthBox etc) are all designed to be run outside, but they seem to have larger openings where the overflow is, its not just a 1/4" hole. One thing I'm considering is drilling holes (maybe 2" apart?) all the way around the res bucket at the level of the 1" air gap, to allow freer air circulation. Any thoughts on that? Would I just be breeding mosquitos? Maybe I need to put goldfish in there....

Below are a couple of pics. So far I have the ProMix/Botanicare Coco blend in the wicks and bottom inch of the pots, and then a heavily amended FFOF/Happy Frog mix, with time release nutes and dolomite lime. There's another pic of some of the girls that will be going into the pots on Saturday (tomorrow its going to be 90º out, Saturday much cooler).

I filled the res's and then added the layers and wet them down each time, and each time the water came out the overflow holes. So there is definitely significant amounts of leaching going on. I think I'm going to transplant, give them a good watering to make sure the soil is settled, and then dump the res's in my garden and refill them with fresh water. I'm concerned about leaving water with a lot of nutrients in it sitting in the res for several months.

Another option is to just let it go. I'll get all kinds of life living in the res, but maybe that's OK. I could add a little Pond Zyme (still researching that) to keep things in check. The res's will (at least on the tall ones) be in the ground up to their overflow holes, so at least the water will be cool and out of the sun.

Plants look healthy bro. I would say swap the water as you stated better to be safe. I am curious how this works for you outdoors, I am waiting to do my own with the fabric pot for outside until I have more info. Hot as hell where I live too.

I put my larger auto seedling outside today in its 5 gal short/wide nursery pot. We shall see how she does there.

Keep up the good work :bigjoint:
