I have a flood and drain set up I did not cover the table in the beginning. Covered it and trough a fan in a hole to keep the air fresh and it ran for almost 5 days and it destroyed my roots at 1 week in to flower
I have 2 x1000 watt in a 5x5 tent with 14000 btu ac sealed with co2 at 1500 ppm and it is amazing i can keep it at 80 deg f or 27 deg cel with no problem! they are 12 days old and on there 4 set of nodes!!! It can be done but is a lot of work but worth the time!!!!! you can almost see them grow...
