apollo grow tents are a little cheaper from amazon, for future reference.
is the room that your tent is in heated by the house furnace? im not sure how you're having such large fluctuations...
if you use a space heater, it needs to be on a thermostat of some sort, that will shut the heater off at 80 and turn it on at 68 or so. usually theyre built into the unit.
I heard that Mars released a new white color led. It is similar with quantum board light.
Will this kind of light be better than the tranditional purple ones? Any journals that i can refer to?
