My Q? is when I hang temp gauge up top temps r 91*degrees which is 2 high & I understand that heat rises 2 the top & lower temps stay at the bottom I have 1-exhaust cpu fan up top (1-passive vent & 1-intake cpu fan at bottom) my Q? is which temp should I go by because I don't want my seedlings 2 suffer heat stress I'm running a small Stealth Micro Grow

You should measure the temp at the top of the canopy. What can you do to cool it with only a CPU fan? You're doomed when the outside temp starts to rise. You should err on the side of WAY too much ventilation next time.

Yes, the plants are living in that environment so that's where the temp should be taken.
