Hello 420,
I'm wondering where you should place a thermometer in a grow room for an accurate reading of the temps. It seems that placing them under the light is not ideal because then its only measuring radiant light when in fact its ambient temperature that counts. This kinda makes sense since temps are always measured in the shade. I placed mine on top/side of the reflector & the difference from under the lights is substantial. If this is the right way to do it then all that matters in the canopy is that the lights are not too hot/too close using the hand method. In any case it sounds that plants can handle higher radiant temps better than ambient. Any thoughts??
Thanks
