The thing is not to let the rootball stay wet all the time. That is why we time our drips and floods. NFT never drowns the rootball, The roots hanging down are water roots and can stay deep in the water. The rootball needs several hours of good air each day to stay healthy. That's why DWC and bubblers works so well, they never soak the rootball.

Get them in a system and the just the top of the rockwool will dry out some and be fine. Your girls will be just fine when they get some nitrogen. Good luck and keep us up on how you did.

OH, what kind of system you got ?
The GH feed chart calls for 1.5ml of Gro, Micro, and Bloom for the "seedling phase". Is that already cut to half or am I supposed to do half of that?

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)?
