Ok, I checked the thermometer and the temp dropped to 65 degrees over night and a high of 72 degrees. It's been really cold here like in the teens overnight, but it's supposed to warm up. They look good although I know the temp should be higher. The closet is really small there really is no room for a heater. so any suggestions? We keep the door open up here when were not here and it's really warm in the room. Should I have the light on longer?, I've read different opinions on how long the light should be on for. Any help would be greatly appreciated, thanks
