Fantastic! That is almost exactly how my free range got started (except mine only had 1 plant originally

)
From my experiences on a near identical setup I can share with you the following....
-I had the exact same issue with the heat bulb. You ABSOLUTELY should have a point and shoot temp gun ($20 online). They work wonders.
-I ended up hanging my heat bulb and uvb bulb SIDEWAYS off my blinds (both my lights point horizontally, not vertically). This way I can keep them close enough to the leaves/cham but still far enough away so that he cant lunge the gap and climb the light (he used to try it at first, I had to slowly move it further and further away until the distance was just enough that he stopped trying). There is a fair bit of trial and error involved
-I have found a growing problem as Clark has been getting bigger....at first he had little to no desire of leaving his free range (it was sufficiently bigger than him to satisfy him). Depending on the age of your cham, you might find he will climb down frequently....I have not yet found a good solution to this other than adding more and more to his free-range.
As long as the free-range is sufficiently big for the cham, he won't leave it. But otherwise, curiosity will get the better of them eventually, so do be careful
