I got this new digital thermometer where the thermometer Is actually placed down in the soil and fed up by a wire too the thermometer where it shows the temperature. its reading ranges from 78-81 degrees. I only have a white day light on. then I have another thermometer on the side a little above the soil (one of those strip ones) that ranges from 81-83 degrees. do you believe this is the perfect day time temperatures? humidity ranges from 65-70. Thanks
