Dang those look like good SIPS ,,,DIY, bottom watered 20 gallon tote with a 5" netpot stuffed with rockwool for a wick. It sits suspended from the bottom of the second tote by 4" elbows. I also used and AIT unit from Modular Hydro to pump air into the wet soil!
This worked very well, I just grew an Auto Ultimate in it and got 305 grams dry from her!
