Is your thermometer in direct light or in a shaded area. The radiant energy in my cabinet throws off the thermometer reading by quite a bit.

my thermometer is in direct light....right where the plants tops would be. is this not where to take temps from?

with my thermometer, the radiant energy heats the plastic case which thermo reads as too high. If I place it under a shelf at the same level it reads much much cooler. Either way I really look at the plant to see if it is too hot. With my cooltube setup I'm not getting those high temps anymore.

get yourself a digital therm.. one that takes inside and outside temps..
put your therm of to the side mid height of your room/box... put the outside wire where your tops should be.. this way you can reed your room and under your lights...

as for IR heat/light theres not much you can do about it other then raise your lights some..
