I bought a roll of black Mylar and will place that over the windows that have original blinds which will be visible from the outside. I should look pretty normal. I was going to have the grow lights on during the day, but I’m thinking I’ll have them on at night to lower the electric bill. Do you think the red light would still be beneficial or just keep it completely dark inside the room? I’ll have to enter the tent at night to keep the plants pruned up, but was going to use a green headlamp to enter the dark room and get inside my tent. If I need to do any spraying (neem, Dr Bronners diluted, etc), I’d do it in the dark using that green headlamp. Thanks again for all the replies
