I read you should take your readings in the shade inside your tent. How do YOU get an accurate measurement of the heat in your tent?
Wrong. Temps taken at canopy level. If it's 80f in the shady corner, it's probably 90+ at the canopy.
IMHO temps should be taken at the canopy level and at the floor/pot level. Both area temperatures are important. You don't want the pots too cold either!
