hey there guys im in santa cruz mountains and get great sunlight and am wondering what i would need to do to heat a 50x30 greenhouse where i could grow in the winter.
Ive heard of people doing it but i know the winters here get down to the 40s and sometimes 30s. My question is how do i keep it warm in the winter? 1000watt hps lights?
any help or experience will be greatly appreciated
