Temperatures over 98f multiply the chance of hermie by a lot. Even if you are using CO² temperature that high can be a big problem.

But it's more how long they were held at that temperature. An hour is fine not good but should be fine. A day is pushing it but longer the that and you are looking for trouble.
Zandor Reviewed by Zandor on . Light heat Take for instance a 400w HPS and a 1000w HPS. Is the heat given out buy the 1000w much more than the 400w. Is it more or less the same? I'm guessing its more but is it a shit load more heat to deal with. Rating: 5
