THIS may be the way to check temps

This is a laser temperature probe that reads temps on a surface from as much as 3 feet away. It is accounting for two kinds of heat - ambient heat and radiant heat. Plants have a much higher tolerance for radiant heat, like that under an hps lamp. But it can still burn and air temps need to be in a lower range, under 80 is best. This is $43 shipped which is a very good deal. It is normally 80 and high priced ones run 400 and up. Using this you can easily check temps at various points around your grow space without relying on the foibles of suspending thermometers here and there and wondering which reading you should go by.
