I used drippers for feeding during vegetative and flowering stages. The medium was rockwool cubes and then grow rocks when the plants were about 5" high. I used 6" square containers and found no traces of rootbind.
Foliar feeding was done with seaweed extract and it worked wonders.
Lighting was flourscent for veg and 400w HPS for flowering.
Nutrients were by Botanicare using only RO water.
