So I have a dr90 (3x3x6) grow tent and yesterday I ordered my lighting setup, a 600w cool tube dimmable mh/hps system. I already have a 6" inline fan and I ordered another 6" inline fan yesterday. I plan on dedicating 1 of the 6" fans to the 600w cool tube and venting it straight through the 2 vent holes on each side of the tent. I plan on dedicating the other 6" fan to the exhaust out of the top of the tent. I plan on buying 2 fan speed controllers and running the fans at a lower speed. I am going to buy a oscillating fan for the floor of the tent. I will buy a carbon filter when it is needed. I already have some out doors stuff going but this is my 1st attempt at indoor growing, I would really appreciate some critique/advice on my set up.
