Sounds good to me. You'll probably want to soak your rockwool overnight to lower its PH before using. I usually stick in in water around a PH of 4 overnight and it comes out at just the right ph the next morning.

keylime Reviewed by keylime on . my new room Hi i have a 8X8X9 room i am going to use a drip to waste system. i expect to have 12-15 plants set up in three 2x7' beds. I am thinking of 6 400w lights to good coveage and less heat. Ballasts, resevoirs, pumps all outside the room as well a ducting. Using rockwool as a media. Do i need to do anything to the rockwool or is it really sterile. Also how can i steralize the nutrient lines from the pumps to the plants? Also does this sound like a good set up? I also have co2 emitter. ajp Rating: 5
