I am using a 5 gallon bucket, drop-in net pot, hydroton, rockwool starter cubes, and an airpump / airstone with GH nutes. (I forget what the technical term for that system is.)
(This is a "DRAIN TO WASTE PROGRAM" (according to the GH feed chart) though right?)
Also real quick, my buckets are from Home Depot and they are orange, should I paint them black to prevent light from getting in?
And how much water should I put in them (I.E. How far should the bottom of the net cup be in the water)?
Sounds like just DWC (deep water culture) or bubbler. The others sound like they have you on the nutes, just start light you can always add more.

As for your netpots and buckets. The water level should be just barely below the bottom of the netpots. The idea is for the bubbles to come up and pop at the surface and splash the netpot a bit. Once roots have grown into the water the level can be dropped alitlle as it is less critical. You are coaching the roots down into the water. If they look like they are drying up before the roots hit the water then you can just pour a litle water over the top much like a drip system again to coach the roots to the water.

Those orange buckets should be fine if you do not see any green algea in them. Or you can hold one up to the light real close and see if you can see light through it. If your light is real strong like MH or HPS then you may want to paint them black.
LOC NAR on probation Reviewed by LOC NAR on probation on . My babies are 2 weeks old and starting to yellow! HELP! My plants are about two weeks old now and they are starting to yellow a little bit, and I also have one thats not acting like its wanting to grow very well. I was wanting to wait two more days before I put them in the Hydroponic system and started feeding them. They were doing great until I transfered them to the rockwool. Now as the new lwaves come in the have a bit of a yellow tint to them. Please check out the pics and let me know what do I need to do? Rating: 5
