Just to keep everyone updated. This is what i did.
I put the 600 back in. Air cooling it with the 300cfm. Temps stay and 75 -80 with the lights on. After so many differnet responses and non really have any simularities i decided to do my own experiment. I built a light flip flop for my 600w light. I have two tents sitting next to eachother. Hut 1 will have 4 waterfarms. hut 2 will have a 3x3 table with a 40 gal rez. My plants are about 10 inchs tall. I am going to do 7 in white pots...roughly 10 inches....and 2 in gordon hugo blocks just to see if hydroton is that much better. I'll post pics if intrest is shown.


By the way i am going to veg the plants for the waterfarm for another week to get them bushy.
