That size room and 6 plants. Go buckets and a 1000 HPS. If you can get a chiller the temps can be higher. Otherwise you need A/C. Water temps should be kept around 70 degrees. Max oxy in water at 68 degrees.

There is one here who runs higher temps but he uses tap water with some chlorine in it. My tap water is sooo bad if I mix one gallon of chlorine water with 4 gallons R/O it kills the shit out of my plants in a week.

Most of the time higher rez temps means root rot.
