This introductory 1-hour webinar presents the essential basics for designing and building your own custom, energy-efficient greenhouse for year-round food production. Energy-efficient greenhouses enable you to grow your own food year-round, without relying on fossil fuels or transported foods. We cover the basics of passive solar greenhouse design and renewable / sustainable climate control methods.

This is the best presentation on the topic I've seen. Just ordered your book.
Thank you for excellent info! My passive solar greenhouse has just approached its first winter and with temperature inside at 5 -10 degrees C. (40-50 F.) humidity is at about 90-95%. Water is condensating and dripping everywhere. How do I eliminate or reduce that? Ventilating moisture out with intake from outside (25 *F) would cool the space below freezing. Is heating only option?
T studs are insulated studs, may help a greenhouse project.
What about greenhouses in tropics or arid places. Anyway to reduce temp inside greenhouse?
56:02 Water is 2 times better than concrete. Wood is 4 times better than concrete. 4in thick wood panels retain heat better than 16in thick concrete.
I am finding window companies don't enjoy greenhouses as the humid conditions ruin their R rating, so it voids any warranty. I'm hoping to find a solution to condensation in a cold Canadian climate using glass.
Exceptionally well done!
Brilliant info, thank you!
Thank you very much for this presentation it was very helpful.
Excellent! Greetings from Montreal!
Why not using double layer Polyethylene Film in the winter. Remove it and replace it with a shade piece in the summer? I'm hearing the Film is lasting around 7 to 8 years.
