Insulate first or you are wasting energy and effort.
An oil-filled radiator-style heater in the grow area, set on a thermostat to go on when temps drop below 65 degrees, will dry out your plants less than a space heater with a fan in it would.
stinkyattic Reviewed by stinkyattic on . Help: Heating a very small grow I am doing a super small grow in an outdoor shed for my own medicinal use. I just started flowering and it's getting pretty darn cold out there already. How can I heat this tiny space without having to heat my whole shed? The grow is only 1.5 by 2 feet but I have about 6 feet vertical clearance. I have thought about : - Super small propane heater... but how would that work? and what about humidity? - Heating blanket or 'propagation mat'... but will 40 watts of heating power make any Rating: 5
