I`m confused about cool tube systems.
I want to buy a 250 w cool tube system with HPS/MH for my next grow, but can`t realy understand, what to buy.
Some questions - are there any self balasted cool tubes?
Do I need two fans for cool tube - in and outtake?
Do I need a carbon filter for exhausted air from the cool tube?
Would appreciate some info on where to order cool tube kit`s.
