- Lets optimize our greenhouses in these scary hungry times! In northern climates it's hard to grow food over winter in greenhouses because it's colder and we get much less daylight than in summer. For instance, I'm at 48.5 north and get about 16 hours of daylight at midsummer (7 hours of sun coming from NORTH of the east west line!) while I only get 8 hours at midwinter and all that winter light comes from low in the sky from the south Remember, you are not only helping yourself by doing this, you are helping others because the strain on the world food supply will be a lot less. So, here's how it goes. Align your high tunnel east west NOT north south! Erect a temporary insulated reflective wall in the north side of the greenhouse, night blankets, etc, in late September, to keep a section of the greenhouse brighter and toasty warm for a few extra months into the winter, and again in very early spring.

Can you buy such a structure? Just buy Chinese one and roll curtains up for summer and take wall down?
I don't think you can buy one. Its just a video for people at the planning stage who might find this useful for some of their greenhouses, so maybe they will have some of them lined up east to west for doing early starts, or early green veg when the prices are best.
@@Brians-Easy-Low-Tech-Solutions Dong Jiany seems pretty friendly and has responded to several people wanting to get in touch with the manufacturer of his greenhouses. he posted his email address in the comments on his youtube channel www.youtube.com/@dongjianyi2492
My impression is that those manufacturers would probably want specific dimensions to have your greenhouse customized, however, it is probably commercial level greenhouses, costing 100,000$ plus labor, probably excluding time for planning etc.
What software did you use to generate the sun path graphics/analysis ? TIA
Oh, it was the gimp. It was fairly tedious. Just the main pic in the background with a bunch of layers with the rays shown on consecutive layers. Then make the background visible with the ray layer you want visible too, then copy visible and export to png. Oh and there were 2 greenhouse layers too. Make the appropriate one visible each time. It took forever.
@@Brians-Easy-Low-Tech-Solutions looks good, I've used a simulator before, but your simplified version has a nice appearance.
