In the write up, it states "The future greenhouse will have a simple shed-style roof slanting to the south but with a much lower angle to allow for a knee wall which will push the ventilation wall further up.".  I have chosen a 5/12 pitch for my greenhouse, but Ceres greenhouse states even a 3/12 is fine if you have a front wall with windows.

I think I found my answer on another thread and reference to another blog.  https://vergepermaculture.ca/2013/07/11/greenhouse-update/

I'm currently laying out the footing for a 30 x 30 greenhouse with a north wall and partial east/west walls in a hill.  I'm a few days away from "finalizing" a list and getting everything on order, but I am arguing with myself regarding the roof pitch....

I'm in Virginia -- 38.9 N Latitude.  I am arguing with myself over a short south wall with a 45 degree angle with glazing on the roof, or a taller south wall with a 22.5 degree angle roof.  

Steep pitch, shorter front wall:

Less Steep, taller front wall:

I read an article once that even though the roof angle should be latitude plus 10 or 20 depending on what article you read, but I've also read that the light loss at a smaller 6/12 roof angle is negligible.  I also don't want to burn anything in the summer if I decide to grow in the greenhouse all year round.

Thank you in advance for any suggestions;

Awesome video, Jeffery.  I too have been obsessed with a Geodesic dome....  

Do you have any idea what angle each edge is on the dome?  Meaning, if I wanted to build a 33' on my own, what angle would each triangle be cut on in order to line up?  I know there has to be a formula for it, but I'm not sure how to go about it.

I'm currently building a passive solar greenhouse and still dream about the geodesic dome.

Jason,

3 years later, I still find your pictures and posts informative, as I am now building my own from an existing block structure, but very similar to yours.  Do you have additional pictures and recommendations or items you wish you would've done?

My "north wall roof" actually faces a bit north-west.  Would you still consider insulating that roof, or do you think it would be a good idea for 16mm polycarbonate?

Thanks!!
