I know this seems like a stupid question, but how do I take the temperature of my grow room? I have two thermometers one on the wall (currently 78) and one on the lid of my hydro champer, with my plants under my light.... under the direct light it is approximately 87, in the shade on the same level it is reading 78..... my res temp is about 75.... I've had my thermometer under the light spike up past 100, while the wall temp was high 80s, I'm assuming that the reading under the light obviously should be higher then room temp? what temp should you attempt to keep under direct light? 400w mh approximately 14" from plant tops....
