Dreadlock Posted March 11, 2016 Report Share Posted March 11, 2016 Hi dudes I have this grow closet constructed. Dimensions are 1.95m H x 0.93m W x 0.83m DI have put a 4" Ezi Air fan inlet at the bottom and 4" Ezi Air fan outlet at the top and also a bathroom extraction fan for more extraction but when I use a 400MH the temps can rise to 35C. Obviously the summer temps aren't helping with the grow box inlet and outlet being directed into the garage but what I need to know is:1) Where should the light sit in the box? Should the hood be at the top of the box with the plant sitting on something higher then lower as the plant grows or should the plant be on the floor with the light being lower and raised as the plant grows? Wouldn't it be easier to control the heat if it was at the top all the time?2) With a cool tube, what is the best way to set one up? Ducting from side to side with a 4"/6" fan? Where does the fan sit in the setup? Could I use the 4" Ezi Air fan outlet at the top for the cool tube/ducting? I'm new to the cool tube side of things - but its becoming obvious its something I needCheers Quote Link to comment Share on other sites More sharing options...
