Planning on using a grow tent with LED lighting,I read that the LED Lightning doesn't produce an excessive amount of heat , do I still need to provide ventilation ?
How much heat an LED light will add to a tent depends on how big the tent is, the ambient temps and how powerful the LED light is. Either way you still need to exchange the air regularly or add CO2 so, yes, you most likely will.
