If someone were to have a little bit of a bigger light, lets say a 1000w Hortilux HPS cause thier MH just blew... how do you put it much closer without frying them? Or do you just go back to start and put them back under flourescents??
Proper ventilation and air flow to help keep your cab cool
make sure you have more exhaust then you have intake
also if you got the room put a 6" clip on fan in your cab
Place it where its blowing right under your canopy but above your plants , you should be able to drop your hps more then
here is a pic of a dresser cab that i made
you can see the 2 fans up top i have for exhaust and 1 fan at the bottom for intake
and also the 6" clip on fan i have blowing under the canopy but above the plant
the hps is almost sitting right on top of her and the temp is 80 degrees
Granted its not a 1000w like yours but the same principle applies
the pic is not the best but you should be able to make out the 6" clip on fan and how is blowing under the canopy but above the plant
