with the pump i have for my flood table 4'x4' it takes less the 2min to flood. it stays flooded for 5-7min each cycle. if not foxfarm nutes what do you suggeset. and i also changed the 1000w mh to a conversion buld 1oooowhps and converted one 400w hps to mh. i had a new reflector made to q 4'x4' to hold all three lights in one refletor with cold/fresh air crculation hope that works. i also increased the temp 10 degress at lights on and off the hymidity at 48% and co2 ppm's at 1350-1500ppms with my new co2 monitor.
