Hi it's me again, my new grow is doing very, well thanks for all the advice.
 
	I would like to know what everyone does to keep their tents warm in the winter.
 
	My tent is in the garage and I have build a iso board room around it  but the plants still get a bit cold. Their stems are turning purple.
 
	I was thinking of getting a heater of some sort.  Something not to heavy on electricity.
 
	Could anyone maybe recommend a heater please?
 
	Thank you very much.
