I used the entire AN 2+ program and I am using 1800 watts. Not much for 1800 I know but the next time will be better for sure!! I have a tray but I top feed with drippers. I only water one time every other day and I have 4" cubes on 1'x3' slabs.mosess187 said:damn good take...what nutes you used?...was the an ebb&flow?...how much wattage?
