Small greenhouse build.

[valley ranch]

Greetings, Wife and I just put up this, at the lower ranch, to start seedlings in. Shaded plastic and roof turbine to control temp. Haven't made the door yet used 5- 3' X 5' window. What you think?

Think you might plan on a little more ventilation than the turbine. Otherwise v nice.

Rule of thumb for passive vents is ~20% of floor area top and bottom.

Woodgeek, Gona go with the turbine If it needs more I'll casement hang and screen a windoe or two. Our greenhouse at the upper ranch has just a1 1/2' X 2' vent on each side. We had a 24' X 36' in Australia and a single turbine really pulled the heat out. We'll see.
