SO your saying that I sould make a cover for it to shade it from the direct light so it doesnt read the heat from the light and just the room temp correct?

It is hard to keep the air in my bathroom cooler because I have 2 cats and they will get to my plants. I just put a fan in my bathroom but my plants are sleeping right now. I wish I had enough room to make a cabinet grow room. I cant really make intake and exhaust as good as I want.
