Well... The problem here isn't that the fluros don't give off a lot of heat at once, but I'm sure over a certain period of time, the air in the cupboard increases because it remains stagnant with no air circulation. Consider just getting a simple rotating fan and see how things work out for you, alright?

Good luck!

Cheers

HELP! excess heat, leaves crisping! hey all, just got back to my grow today and the leaves have been getting patches of golden colour on them, its hot in that cupboard, despite using fluros and being at least 2 inches from the tube (200 watt gro lux). theyve gone crispy there, though ive noticed that is only on the broader leaves lower down, i guess cos theyre not able to deal with less humidty and heat so well. even the thniner leaves have curled in a little and are kind of pointing upwards, no pics though im afraid though im Rating: 5
