Lamp heat / room tempature

Guys and Gals, I have my plants about 6 inches from the 150 watt HPS bulb, The temperature when the thermometer is in the direct light is about 100degreesF, In the Shade it stays about 90degreesF. I have a huge fan that keeps the air circulating/keeps the plants cool.

Was wondering what I should look for if that plants cant take it...

thanks

not back the light off at least 12-14 inches ,, maybe more


100 degrees F wont KILL them but it will severely stunt growth

add a fan that ACTUALLY exhausts the hot air OUT of the grow room
