Its not that wet though, only 1/2 of the top soil is moist. I built this for soil, im not going to just drop it and rebuild for a hydro set up.
That is a typical newbie mistake and we've all done that... with soil, you don't just water a little bit at a time, and often, so only the top 1/2 stays wet. That will lead to all kinds of problems. You're supposed to thoroughly saturate the soil and then do not water again at all untill it's almost completely dried out or leaves start to droop, then thoroughly saturate it again. I started with soil too, but trust me, you will be doing yourself a huge favor going to a hempy bucket type container. Build at least 1 or 2 milk jugs like I suggested and at least try it out. You can get an 8-quart bag of Miracle Gro (non-fertilized) Perlite at Home Depot or Lowes for $4, and that will do 2 milk jugs. Do 2 soil and 2 hempy side by side and compare. 100% perlite is impossible to over water! and perlite is much easier and cleaner to work with than soil.
Another thing you could do is just fill the bottom 8-10" or so of your bottom tub with perlite, put a 1/4" nylon hose barb fitting through the front of the tub about 1" to 1-1/2" from the bottom. Then put a catch pan under the hose barb when you water to catch the run off.
I know soil seems like the safest and easiest way to start, but it's really not. Hempy containers are just like soil containers, you just water more often and they grow way faster.
Another problem I see, is it looks like your lights are in a fixed position? that's no good, you need to be able to move them up and down, or even side to side when the colas grow up towards the very top of your container, and you need to have them very close to the seedlings, the distance those lights are from that seedling, it's gonna stretch like a mother.
