yeah i use degrees celcius not fahrenheit...
So you'r saying 32 ° wouldnt harm my plants anyway ?[/quote
It depends if its radiant heat or 'air' heat. Radiant heat they could handel around 32c, but if the air around the plant is 32c than your gonna have problems. Take temp reading right at the top of your plants, and then further out from the plant, if its 32c, say, 30cm away than it's to hot, if it cools down quikly when you move it away it should be fine.
