Im in the midwest, and have a building that no one ever goes in. But it dosent have heat. It gets like -10 and goes almost to 30 latley. If i had them in an small closet would the lights heat it up enough?
This depends on a few factors. What type of lights, how big is the room, what type of ventilation? How exposed is the area to the elements?
its not exposed to the elements. i have a 250 watt bulb, that produces tons of heat. Its a wooden armore, about 3 feet high.
I was tinking about just veging untill it was warm enough outside, than move it outside and at the end of the season have a monster plant.
