Just a quick question, i have 3 seeds in rockwool surrounded by hydroton in 3 5gal DWC buckets. I germinated them in a paper towel and put them in the cubes and hydroton. How far up should my h2o level be since they are only a few dats old. I have the cubes sitting about 1-2'' off the bottom of the net pot with hydroton surrounding cube. Currenty the h2o is just touching the bottom of the net pot.
