if you can, put your control on something that can go up and down with the growing cycle of your plants. towards the top of the plant is a good place to start. check the reading with more than one thermostat to make sure you are getting a good controlled reading of temperature. try not to have your fans blowing directly on your control.

You want to put the t-stat,high! And make the fans draw not blow.If you use an oscillating fan use it on low.Use the controller to slow or speed the fan till you tweak it to correct temp.trial and error.
