Hey guys just wondering if I could get some opinions on t stats. Mainly what I was wondering is proportional vs non proportional. We have been heating with heat lamps in glass tanks but we are changing some to a rack system. I am gonna use flex watt and a tstat. There are some decent non prop stats out there but I was thinking about buying the herpastat intro I am only heating three tubs. Do you think proportional is worth the extra money. Is the temperature differential of two or three degrees really that big of a deal. Any thoughts on this would be appreciated . Also what about night drop feature does anybody use? Thanks.
