Hi,

I bought my friends Exo-terra 20gal and I need an UTH and the seller told me I would be okay with the Exo-terra Heat wave desert and that it was all it needed. So my question is : are they self regulated at 90°? (to know if I need a thermostat)

If anyone owns them tell me their temps.
Also if someone owns a Heat wave rain-forest tell me if you need to regulate the temps.
Thanks,
Fred.
