You should not have a problem with the temp when the lights are on as it is winter here in the uk now. There will always be a chance the helicopter will see you but that is the risk you take. Oh and just remember the risk of snow, you don't want to be the only house on the block with no snow on the roof. If you need any more info just ask and I hope the helps.
thanks for the reply mr samsung that was something i hadnt thought about. is there a sure way i can keep my grow cool during the summer months?
