I know lamps don't provide a lot of heat. My windows in my house are awful as well as my room has 2 outside walls, and on top of that, I live in Wisconsin. I'm doing what I can. And if hydrofarms arent at all accurate, then why does half this website suggest I get one? As well as the accu-rite. Now I'm just angry, almost EVERY single post in a thread I made earlier suggested both of these. What the hell.
