What if you slid the inner container inside the outer container without cutting the inner container shorter , by leaving it full size the top would stick out above and give more space for soil?

Yeah depending on how much soil I can get in these I may do that.. I think if I can get at least 7 gallons I will use 1 per plant and scrog some monsters!

[QUOman ="meangreengrowinmachine, post: 13352701, member: 609408"]These are also so nice and neat! I could just cut a hole in the center lid and put a seedling in there and use it to retain moisture![/QUOTE]
Yea man being able to snap that lid on sounds trick custom

Hmm there is an overflow hole in the design but it was left out of the plans so I didn't add it... where do you all think it should be and how large?

Doesn't the Inntainer have a fill indicator tube and not a drain hole? If you're just doing a drain hole then you want it about an inch below the soils container bottom so that it maintains a 1" air gap between the water and the bottom of the soil. It could maybe be 1/4" hole and be okay.

14 gallon intainer!

I did a variation on that, where I dropped a whole 14 gallon into an 18 gallon, instead of cutting the top one. That allowed me to have about 12 gallons of soil over 5 gallons of water. Worked nicely, but it was a bit tall.

Yeah I did that so just make a line
where you want your air gap and don't fill past it right? Also the grommet and barbed elbow I think is the biggest pain in the ass in making these imo lol

Yes, I put a line on the tube at 1" below the lid level as a fill indicator, and I cut it about a 1/4" below lid level as an overflow opening.

I love the overall concept, you can keep an eye on the water rising as your are filling. I have a watering can with a thin spout that I was able to squeeze a length of garden hose over. I can put the end of the hose right into the fill tube and not worry about spilling while I watch the water rise in the clear tube. Mine did tend to fog up over the course of the grow, but my city (or my old house) might have unique water.

In theory NFT mat should be perfect. They are used to grow marijuana in tubes might as well use them to grow on a table.

1st of the individual sips screens.. hope it's high enough and wondering how I should attach it to the SIP... maybe some large pvc end caps hot glues to the side on the SIP and just set the ends in? Just don't want to have the screen moving around too much when moving the sips from veg to flower... also wondering what you guys think on this... so my seedlings are already about 10 inches high in their starters (large yogurt containers) and I want to bury the stem length when transplanting... but I'm worried that doing so I will end up putting the roots directly on the wick.... will this cause issues with too much water and possibly drown the plant or stunt transplanting? Should I plant it off to the side? (that will kill my ocd lol) what do you all think ?

Couldn't you just drill holes in the pvc end caps and bolt the caps to the lid edge and then the legs could slide into the caps? I wouldn't use hot glue... that could make a mess.
