Growing year round in a passive solar greenhouse without heating

Growing year round in a passive solar greenhouse without heating

I am growing year round at Olds, Alberta, Canada. Our latitude is 52deg and elevation is 1000m. The passive solar greenhouse does a great job in extending the growing season in such a challenging place. No artifical heat source is used. The only heat source is sunlight. Passive solar greenhouses are very cost effective and environmentally friendly solutions to vegetable growing. Video taken on Dec 28th, 2020

    Greetings from Edmonton – amazing !

    Dude, just move somewhere warmer

    Building my first greenhouse in Sweden this year, starting a bit smaller than this though! Am in the South of the country where it’s pretty warm (minus 15 or minus 20 was the coldest this year) but we do have similarly short hours of low sun in the Winter. I have hope for some leafy greens to start with!

    Anyway, I’ve been doing a lot of research into Chinese greenhouse designs lately. Lots of really interesting ideas!

    Dong Jianyi why did you decide to use clay to retain heat instead of water? I intend to in the future do a similar project as yours, and you seem the best source of information. Excellent greenhouse.

    Thank you for this clip. Interesting. We have same problem as in Canada. Winter can be cold and we can enjoy sunshine only about 5 hrs in December 28th. Now in March 20th we have sunshine 12 hrs.

    Cool video! But I think your audio is a little messed up, I only hear sound coming out of my left speaker

    This kind of technology turning frozen wastelands into fields of food will save humanity.

  8. Arshan Aidun on May 8, 2021 at 1:13 am

    Is there maybe a solar power timer setting led floodlight that could run for a combination when there’s no sun so you could have longer photoperiods even if it’s not full spectrum or whatever it could suffice. Just a thought

    Have you seen Greenhouse in the Snow"? He is in west Nebraska, using geothemal tubing to support the solar. You’ve got an amazing set up, thanks for sharing.

    as someone who has the intention of buying my own farm in Northern Quebec and farming there in permaculture, thank you for this video!

    This is brilliant. Do you recirculate the warm air under ground in the summer to heat the ground? Maybe you show this in your other videos

  12. Jeff Paetkau on May 8, 2021 at 1:19 am

    You are my hero!

  13. Slimmy Kimmy on May 8, 2021 at 1:20 am

    Why don’t we live in these things

  14. Bryan Camarce on May 8, 2021 at 1:20 am

    a compost pile generates heat overall… serves a dual purpose, as it makes fertilizer

  15. Apex on May 8, 2021 at 1:21 am

    Very cool and then I find out you’re Canadian too!
    Cheers from BC.

    Olds!!!! I live in Red Deer. Can I come see this maybe later this year or next (pending how comfortable society is with covid). Let me know. -James Walper, Libertarian Party of Canada (candidate in 2015) (never-mind the politics though, I’m just wanting to learn!)

    2020 was the darkest coldest time, period

  18. JABN creations on May 8, 2021 at 1:25 am

    oh wow you are in Olds, I lived there for a year. Now I live in Southern China, no snow here.

  19. Phoenixx Gillies on May 8, 2021 at 1:26 am

    Amazing! Love it! 👍✊

  20. dfgdfg on May 8, 2021 at 1:26 am

    Impressive!

  21. imvarda on May 8, 2021 at 1:29 am

    Nice, now replace it all with some form of aquaponics and vertical farming and you could have lots of growth in that small place. Xidada would be proud.

  22. Roman T on May 8, 2021 at 1:30 am

    how much to build that greenhouse?

  23. s on May 8, 2021 at 1:31 am

    Burn some propane for co2 and heat. It’s cheap. Will increases yield

  24. lord pickle on May 8, 2021 at 1:33 am

    Hmm, nice. I’m from the heavily forested "Canadian Shield" area but right at the southernmost area along the US border is a large plain that could probably be used for food. I’ve often wondered if something like this could be done, nice to see it can.

    This seems like a lot of inputs for some winter kale. I would suspect shipping, even with a diesel truck, is more efficient and carbon constrained. Especially after one of those big hail storms hits the bullseye, you’re in the belt after all…

  26. Paul Leitner on May 8, 2021 at 1:34 am

    Very cool

    Brilliant

  29. Spaide man on May 8, 2021 at 1:36 am

    i think the audiences are more interested in how your greenhouse work

  30. ipeteagles on May 8, 2021 at 1:36 am

    impressive endeavor

  31. ZalyQQ on May 8, 2021 at 1:36 am

    WOW. Im from SK and i could not imagine growing outside without heat. I subbed just because we’re neighbours. How did you learn your methods for growing over winter?

  32. B Riotous on May 8, 2021 at 1:37 am

    It’s sad because while this could be amazing for feeding people all year around Canada, I feel like this is going to be used for profits.

    Do not sell to Bill Gates he is your competitor in the USA !

  35. Alen Devlin on May 8, 2021 at 1:40 am

    If soil and knowledge is great, you can grow vegetables anywhere including in your apartment.

  36. Dan Torke on May 8, 2021 at 1:40 am

    I heard you keep all the "good stuff" in the back

  37. drom techmarine on May 8, 2021 at 1:42 am

    Farmers are good.

  38. Ryad Arlan on May 8, 2021 at 1:43 am

    I could spend a week showing you upgrades for that thing but i dont ever see results.

  39. King Smith on May 8, 2021 at 1:43 am

    nice 👍👍

  40. Amin Abbasi on May 8, 2021 at 1:43 am

    Thank you for sharing your knowledge, can we scale this greenhouse?

  41. A M on May 8, 2021 at 1:47 am

    I have an input: can you set up an methane digester!? Because then you can get gas for electricity from the waste you have. Great job.

  42. Wen zen on May 8, 2021 at 1:50 am

    why don’t you use LED light, with a solar panels to help in growing?

  43. Nyota Uhura on May 8, 2021 at 1:50 am

    thank you for sharing your greenhouse

  44. airpeguiV2 on May 8, 2021 at 1:51 am

    This is just amazing, thank you so much for what you do and how you do it. Wishing success from Europe.

  45. CMAenergy on May 8, 2021 at 1:51 am

    What do you use for storing heat on that north wall

  46. s on May 8, 2021 at 1:53 am

    Great job dong

  47. Kęstutis Šliauderis on May 8, 2021 at 1:54 am

    wow! amazing!

  48. KIA on May 8, 2021 at 1:55 am

    Grow weed, not tomato’s you can’t smoke tomato’s lol jk, but good job tho keep it up

  49. Pat Glenn on May 8, 2021 at 1:56 am

    That’s fantastic! I’m curious how you fared a couple weeks back (in February when it dropped to minus 40.

    Also; Can you tell us about the technology of your greenhouse? How is it insulated? Double glass? Triple?

  50. Blue387 on May 8, 2021 at 1:58 am

    Very nice
