mickrick Reviewed by mickrick on . Temperatures?? Too cold for bud? to cold for Veg? Currently i have 2 seperate rooms in my garage. One for bud one for veg. I only have one space heater for it all and due to it being so cold this winter (29F-50F) i believe my flower room is not showing optimal results. I currently have my space heater in my veg room and keep it at 70F. I would like to move my heater over to my bud room but am worried about the cold weather killing or somehow damaging my veging ladies. I have tried to search but all i can find is temperatures it is supposed to Rating: 5
