Setting up a frag system in the garage. Doing things as cheap as possible for now. Picked up a used chiller and a couple gyre 350's for next to nothing. A couple of flood trays and resovior from a hydroponics warehouse close to my job. Starting with a couple black boxes and a cheap return pump. Just added water on Sunday. Haven't gotten lights for the top yet or a dosing pump. Running a ATO in a bucket for now. Flood trays are 2 X 4 and the chiller is plenty big to add a couple more even in the south florida heat. Let me know if you have any suggestions. Thanks.
