Thanks for all the input guys, I believe I am over thinking the temps at the moment. When summer is in full swing I'm sure I'll have to really worry then. To clarify where the temps are taken and the differences here's a pic.
The temp in red is taken directly under the light at plant level, my thermometer is also black which might be making it read high.
The temp in blue is taken in the corner, not directly under the light but still at plant level.
The yellow is taken outside the tent near one of the passive intakes.
Should I consider the blue temp to be the most accurate vs. the red?
