well not to question ur intelligence or nothin, but in the US, growing mary jane is illegal so to help make ur grow room a little bit more stealth, growers use the lights during the daytime where the temperature are already up so that at night, when the lights heat up the room, the temperature wont show up on some sort of thermal camera or radar that law enforcement may be using to investigate
