If you heat your grow room with a oil filled radiator or other source with a built in thermostat I have a few questions for you.
I’ll give you my details first, I have a room in the attic of my shed first time trying outdoors in winter I can’t use my basement anymore long story. I use a enclosed heat lamp and a ceramic space heater for supplement, my only choice right now. Humidity is all over the place and so are my temps. At 16% humidity I have to turn the thermostat way up to keep temps above 65, at 30%+ humidity I have to turn it way down.
I’d like to know your experiences.
What are your temp variations? Mine are about 10 degrees if humidity is stable so heater kicks on at65 off at 75 degrees.
Have you noticed humidity affecting your thermostat? If I have mine set perfect at 16% humidity to range from 65-75 degrees and humidity rises to 30-40% then my temps jump up to 90+ degrees.
Not looking for why don’t you just get a humidifier yada yada, I’m looking for information on how your thermostat performs.
I’ve never had to heat a grow room before, it’s been trial and error and I just got my room setup with a moisture barrier and expect humidity levels to level off, up to 40% for the first time. I literally had to tear my room apart and start from scratch after all my humidity was sticking to my walls behind the insulation. No mold, no worries, saved my girl in the process (heat and cold and humidity stress) just trying to figure out this temp issue so I don’t have to check every couple of hours.
She is 15 days old been stressed for about a week still growing pretty well considering.
I know it’s not that bad but I don’t like to see her stressed at all.
