What type of mesh should I use because of the heat. I know the temp of the tank top under the 400w is because when I was baking the paint with an old light (a regular 400w 6500k) I took a temp reading. I was just wondering how hot it would be in the hood. I am planing to put a fan or two in when I get time to find one.
