you should seriously consider the ppk system. ive ran soil,coco,rdwc, nft tables, aeropnic type mist systems. top drip ppk buckets grow super fast, yield amazing, an the ppk system is a wonderfull concept. once you learn the water timing shits a breeze. very forgiving an little equipment to fail. no chillers. quiet. efficient an very very low maintenance. can stress this enough!!! tons of ppk threads to check out
