Flexwatt in divided T8

[Eric Alan]

Eric, can you explain why you preferred the back to the middle? I've heard people like one or the other but never their reason why.

I prefer having it along the back vs the middle because of the glass front of the T8s. When I had it in the middle, my BPs were typically found towards the middle in the back when they would be on their hot spot - never towards the middle in the front. Everything else being equal in the T8, my belief is that they were more comfortable towards the back where it was that much more dark and secure feeling for them (which is why I switched from the middle to along the back).

Having said that (and reading it myself), one could make the argument for having it down the middle which creates 4 zones (dark/cool, dark/warm, light/cool, light/warm) vs only 2 zones if the heat's across the back (dark/warm, light/cool). My recommendation is if you don't go down the middle, go with something smaller than 11" down the back - it's entirely too wide and creates too large of a hot spot for them.
