Ok, conversion was completed in ~90 minutes. The old system is cleaned and on backup in case this one fails for some reason *knock knock*. The roots are starting to gradually sag into the water from the brick shape it was from being cramped into those bins. How much of the root mass should be in the water vs out of the water?

The only problem we ran into is that the sides of the res bow when filled half way with water, but the good thing is that duct tape holds them where they should be! :thumbsup:

Weedhound: Since you wouldn't use plastic to cover the open area because of air flow, would it be OK to just leave it open? The foliage is THICK over the area, so not much light can get through. The only real danger would be leaves falling in there and getting in the water/roots and maybe doing harm? I dunno, I'm new to this whole DWC thing obviously.:jointsmile: Here are some pics!
dejayou30 Reviewed by dejayou30 on . Third Grow I am at Day 19 of flower in my third grow with 9 Master Kush. My bins drain completely this time around and my roots are super huge which I think I owe to the drainage. I am having some yellowing for some reason, but I just changed the res and upped the PPM to 1100 last night so hopefully they will turn around. The plants really took off in veg which I was not expecting, so I had to tie a few of the plants down to keep them away from the 1KW HPS bulb. The first pic is my whole grow area, Rating: 5
