Always take the temp at canopy level. Fine tuning of intake and exaust fans can help greatly.

You need to move air into the grow area at floor level and move it out at light level. I have four fans running to do this. Heat is why I don't even try to grow in summer. If I can't keep temp at plant tops below 80, I don't try to grow.
