I built this small lean to Greenhouse off my shed . I'm in NJ and it's been sort of a raw cold rainy Spring start.....but the full Sun days We've had caused temps of 125° so with the Vent window open I put the shade cloth over as I raise Coleus... It's much better
Now temps are at 85°....except lately with rain & temps between 43°-59° .....I've been using a small ceramic heater on low which keeps the Greenhouse temps at a constant 80°..... But I'm concerned with " Air movement " ...the fan on the heater is on low...the heat seems dry.... Should I Vent every few hours to get good Oxygen movement?? Without the heater temps eventually fall to around 48°..... I'm afraid to lose my Coleus plants
