I'd like to know too. There's probably a study out there somewhere. I do know that anything more than a 5.0 burns my plants. 2.0 4-6 hours a day seems to be the best for me.
Flexarium. (exo-terra one) I've had a lot of research on this and asked a lot of questions. The 10.0 gets reduced alot by atleast 50% due to the exo-terra mesh.
Ok cool just making sure. It should be just fine for your plants. Lots of people have no problem using the UV 5.0 bulb with plants which would be equivalent to the 10.0 given your cage.
You can just add on extra flourescent lighting if you want to help your plants. No UVb type bulbs will do no damage to your plant in normal conditions.
