cool flourescent lights. i'm not sure but a cannabis plant might be able to endure temperatures like that.
EDIT: if you're gonna flower with flloro's you need "warm flourescent lights" which give off more of a red spectrum.
Cas Reviewed by Cas on . growing question I live at 7,000ft and have a plant that I started about 2 months ago, it's about 2.5ft high, but no buds or anything yet. Do you think it's too late in the summer for it to get buds? The season first frosts will start here in about a month. If there are no buds can I still smoke the leaves? Rating: 5
