I have a small veg space with sufficient air exchange, but still experiencing too high a temp on a 24 hr cycle. I added two 250 watt coil-type fluorescent lamps in reflectors and placed them slightly lower than the 400 MH. I've turned a few bumpers 15 - 20 yrs back, but not much exp with the challenges of significantly smaller space. Question: Can I run my HID 12on/12off + the Fluor running 24on, simply to control temp, until I flower and switch to 12/12 all around? Anything I should be concerned about other than some slower growth?
