my grow room has wide swings in tempiture. from 70 degrees F if i leave the fan on in the wrong part of the day to 90 degrees F if i turn it off. the thing is i have to work and go to school so i am not at home to monitor it. what i need is a termostat that turns two fans off and on when the tempiture gets a certian degree. Can anyone help me with a brand name or place to get the kind i need? i am a nubee so i dont want to buy one and then have it not do the job. and i am not an electrician
