When I ran hydro the top of my netted pots where 1.5" above the water line, most of the roots stayed wet all the time. The exposed roots were able to supply enough oxygen.

I always start much weaker with the nutes and build up to full strength over a few week period. You can always tweak up your nutes but you cannot take it down real easy if overdone.
Hempsouth Reviewed by Hempsouth 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
