at the most i was gettin 65 and sometimes 70, which i know is nowhere near enough and that was even at the basking point. I had a heatmat set up inside the flexarium so the chams could sit next to it when the basking light went out. The basking light is 100w and both of this work fine on my glass viv, thats where the chams are atm. But when i get a bit more money as all my money goes on these chams, will see if there is any other methods out there designed for flexarium. Thanks to all:crazy:
