heat vs light? how hot is too hot?

The hottest part of the plant is at 82.2 degrees. You can see the thermomoter in the pic. But, I'm noticing that the pistils look just a bit shriveled. More so than the pistils a bit farther away from the light. I hate to move the light any farther away because I like the intensity, and its perfect for the middle of the plant.

TooSober put your hand on top of your highest cola, just under the light. Back of hand towards the light.

If it's comfortable for your hand you are OK, it it's hot your plants will burn.

The temperature near the outer wall will not be the same as directly under the light.

A light mover will let you keep your light closer to your plants.

Making a bowl shaped canopy will keep your outer plants/branches closer to the light.
