So I am getting a Hermann's tortoise very soon, and I am worried about the amount of lighting her enclosure has. It is 100cm width 200 cm length (will be upgraded the bigger she gets). For the basking spot I have a 100W heat bulb, and for the rest of the enclosure a 85cm long UVB strip light. However, because the enclosure is 200cm long im wondering if I need more than the 85cm long UVB strip? Should I get two and line them up so that it extends along the rest of the enclosure too, or will just one strip be fine? Thanks.
