If you are using T-5H tubes, be careful of their heat output. Regular T-5 tubes don't generate near the heat. It also depends on how many tubes you have in that fixture. I am using 6, T-5H tube fixtures and have to keep my orchids at least 2' away. Otherwise, they "sunburn".

The reason it's so hard to lose weight when you get up in age is because your body and your fat have become good friends.
