HOW CAN REDUCE THE FREQUENCY OF ON/OFF CYCLES OF MY AUTOMATION IN APP?

I recently purchased a T3 Thermoforge Heater for my Grow tent and have been using it to dial in colonizing temps for my mushrooms. It works amazing, however the frequency of the on and off cycle worries me both for safety reasons and in part to my electric bill. My cultures do not need to be exactly 75% at all times, I’m wondering if there’s a way In app to balance the on/off frequency with a more forgiving range of temps. any advice welcome!
