Lights: DIY COB ( 8 ) Cree cxa/cxb-3070 (2-5000k, 2-4000k, 4-3000k) 400w with everything turned up, run at about 350w during flower
Container/Medium: DIY SIPs, coco/peat moss lower (for wicking), FFOF/Happy Frog amended soil above. They hold about 10 gallons of soil, and about 5 gallons of water.
Strains: (1) Bruce Banner #3, (1) Chemdawg OG x Rug Burn OG

SIPs are new to me, this will be my first run with them. For more info on SIPs, here's a thread.

These girls started as clones I picked up on March 9th, and they have been vegging in 2 gallon pots since March 15th. I will veg them maybe two more weeks in their new pots to give them a chance to stretch out and find the res before I flip them to flower. They were intensely root bound when I transplanted them today, Bruce Banner grows roots at a crazy rate.

The last few runs I've used screens to help separate and support the branches, but have not used them to "train" the plant in a very long time -- this time I will be training them under the scrog old school. Part of that is because they vegged for so long, part of it is because of height restrictions. It's my first time using a double scrog, the second level will just be for support.

The plants were about 20-24" tall in the 2 gallon pots, and the space between the soil level and the scrog is about 14", so there was quite a bit of bending to get them in. I'll give them a few days to adjust, and then trim them based on their growth patterns.

Here are some pics to tell the story. Sorry, its a real small space and I'm not much of a photographer these days.

Good Gosh its going to be a Jungle of Colas,, if I was a jedi master I would say "Your training is complete",, dumb i know, but look at that set up,, top notch bro

Thanks everyone. I'm fine tuning as I go, but I think this one will be a fun ride. :)

This is what the girls looked like before they went in

Looks good Rob. Once the roots hit the rez its on man. Buckle up. Lol. The growth I'm getting from mine is astounding.

I'm almost a little nervous about that! lol I've got two big girls in a 2x4 tent, I'm hoping they put all of that energy into buds and not stretching!

I hope it goes smoothly, I'm new to this so you may learn a new trick, or just what not to do, which can be just as valuable. ;)

Hahaha, Thanks buddy. I've definitely got the right idea, now we'll get to see if I can pull it off. If this run fails, I'm pretty sure it'll be "operator error". LOL

However you can manage. I'm designing a semi SIPS approach, with 5 gallon Homer buckets in 27 gallon tuffboxes.

I've been experimenting with them. I read what a few people have shared here, looked at Earthboxes and Octopots, and found a company that gives away DIY PDF files on how to build them using Rubbermaid bins. I read about all that, and then took things from each source. Some people drop one 18 gallon bin into another, I had some 14 gallon bins, so I used those sitting in an 18, to give me the gap to hold 5+ gallons of water.

The really big enigma is the wicks. Lots of opinions about volume and amount of porosity. I have no idea what works yet, I'm hoping everyone will share their results. I did two versions, one with three smaller wicks made out of 2" PVC, and one made out of a single larger perforated drain pipe (like the kind they use in 'french drains', and it only comes in 10 foot sections, so if you're ever in Oregon I can spot you a few feet of it...).

I got pics....

I'm very curious to see what that looks like... ?

As soon as I build one, I'll take a few snaps and post them. I'm planning to make it brutally simple, basically the 5 gallon pail sits on the floor of the tub.

Instead of watering from the bottom, I'm thinking of topfeed with the excess running into the tub for roots to soak up later.

Maybe this is more a hempy style? I'm not sure of the relevant terminology.

There is a lot of cross-over between Hempy buckets and these, and other styles of hydro/hybrid pots.

There are a few things that the commercial makers of SIPs stress, and I don't really understand why it works this way, but they are unanimous about it: they all say that the 1" gap between the water and the soil is critical to this functioning properly.

In the SIP thread I mentioned in the first post, @Tim Fox put a video in about a system that uses a drenched aerated water/soil mix via air stones. So there are a lot of ways to go about mixing water and soil -- but they need air in the equation. I'm sure you know more about this than I do, but just having a standing water without some sort of interaction with air will (as I vaguely understand it) create root rot and not water roots.

Then the roots would rot in the bottom of a SIPS setup. I think the key is not to let standing water remain for too long.

We've already crossed the line past my knowledge or experience... I believe the answer is a question: Then how does hydro work? Its my understanding that however it is that hydro systems allow the roots to survive without rotting, this is attempting to use the same principals. I've never done hydro, so I'm just repeating things I've heard/read.

I'm also using an air stone in my res, although all of the manufacturers of these things (that I've read about) claim it is unnecessary (Octopot says if you use one, don't let it run more than 12 out of every 24 hours, because it can be detrimental...). As you can see, I have bits and pieces of information and I'm still trying to put the puzzle together.

Ok. Weighing in. I'm running massive diy octopots. Here is my 2cents but it's in regards to my type of setup which is a bit different than Rob's.
-bigger/longer wick is better. In my case. Not desirable to have rez go dry.
-water gets drunk too quick for roots to rot. My roots do sit in the water w an airstones
-once the top of the medium dries the gnats start dying off.
-nutes should be in the soil not.in the rez or you will have to pH the mix. Most I would add is silica
-use natural cal-mag supplement in soil. (Good quality organic dry ferts)
-personally. The occasional quart or two of tea top fed seems fine so far. Just don't over wet the soil w lots of top watering.
-the plants seems to live this setup being perfectly moist always.

Hold on... I'll go snap a photo of the roots of the blu balz. Like holy hell.

That is an amazing set up, I look forward to seeing that through to harvest. Thanks for sharing your info.

It would be great if at some point we can come up with a set of ratios -- water to soil to wick capacity. There are so many variations, a single formula is probably not be possible. @hyroot mentioned somewhere that he uses a plastic cup with relatively few holes in it for his wick. But I think some folks using SIP systems are still top feeding somewhat regularly?

There are so many ways to go about this... I'm sure I'll be dreaming of SIPs tonight.... g'night all, I'll check back in in the morning...

5 gal build
5gal wide nursery pot
5 gal home depot bucket
Pvc. I used 3/4"
18 oz party cup


20160421_175746.jpg
In the 5 gal nursery pot,
Cut a 3" hole for wicking pot and a 3/4" hole or what ever size pvc you use.

20160421_175759.jpg


Make sure to cut the pvc at an angle at one end. This end will be going through the pit into the bucket resi. So it's not to si k t flat and water can flow out easily
20160421_175811.jpg

Make some holes in the cup

20160421_180029.jpg


Pack the cup tight full of coco and place it in the hole in the pot. That's in the bucket

Then add some soil grow your plant


Kona sunset
All living soil

It holds 1 1/4 gallons of water in the resi. I water twice a week. Plain water only
