ok heres the thing,,
i have 445watts of cfl in my cupboard which is doing o.k so far temps stay bang on 74
but... i have just bought a 400watt hps and put it in there instead of the cfl's as ive just started flowering
but now my temps are around 85
i have 2 pc fans as inlet and 2 larger pc fans as exhaust with a large fan circulating air in the cupboard,
can i put the cfl's back in and put the hps on a seperate timer so that it comes on for an hour and off for half an hour too cool down through out the 12/12 cycle to keep temps down whilst still getting the extra boost from the hps?
would this damage the ballast or bulb or be bad for the plants?
i can only cut holes in the same panel of the cupboard as my exhaust fans are (top)
so can really only add more exhaust or circulating fans
