Thumbs up Moonshadows!
I have some fan and ventilation issues that need to be addressed before this years hot weather.
I built my 8' x 12' greenhouse last year. I use it for propagation mainly but also want to keep my in ground greenhouse veggies all the way through the growing season.
I built my greenhouse with 4 close-able base vents at the corners, a storm door with 2 foot square screened window and a solar/piston window at the rear.
Not enough ventilation! I put in a cheap 20" box fan which helped but my tomatoes went to the ceiling and did not do well with temps to 110 degrees.
In the pic below I show 2 additions I made this year. A 16" oscillating fan and a 6" 425 CFM exhaust fan (green in upper right) I picked up at a garage sale. The blue square is the 2'x3' solar/piston window.
Questions:
Is this enough? I am thinking maybe a couple more $9 closesble vents at the midpoints? And maybe another solar/piston window near the peak?
How many square feet is your greenhouse Moonshadows?
