Really good video. One criticism is please let the person you are interviewing talk uninterrupted as there seems to be a lot of interjection by the interviewer and he ends up talking over the person he is soliciting information from.

The internet has made meeting and learning from amazing people possible on a level never seen before. This farmer/carpenter is amazingly talented. I love his passion.

We had a very similar structure (minus the underground feature) we called a solarium along the side of the house. All we had to do was open the sliding glass door from the house to the solarium in January to heat up the house. Cement floor. Grew lemons year round. Oregon.

I bought property next door. It was owned by an engineer who wrote building code all over North America. He built one of these in the late 70's. He also installed a compostable toilet, and the green house was south facing and brought heat back into the home in winter. Very cool and way ahead of its time!

Wow thanks for all the positive feedback on my project! I’ll try and answer some questions. What wasn’t shown was the excavation with a perimeter drain of gravel and drainage pipe. Buried air exchange pipes would have been impractical due to drainage, but I like the idea. This could have been built of dry laid stone and it would be beautiful but what I have is small irregular rocks. The building it is attached to is a repair shop not a house, and the siding has an air gap behind it, but please take care with moisture attaching to your house! The rafters are full 2x4 hemlock, selected to be close to perfect from my local mill. At least equal to “2x6”s from the orange or blue box. I’ll let you know if they weren’t enough! Cost breakdown: Store lumber 1100, lumber from sawmill 500, wire panels 400, polycarbonate 1900 delivered, extrusions 400, screws etc 200. I have a 40 year old 23 hp loader tractor and a 1969 jd 450 dozer, so I am just counting materials. I had the fan and vents. The thing I like about the electric vents is I can set the temp within a few degrees, but the solar ones work too. I recommend your local Mennonite farm supply for polycarbonate and vents, in ny and pa there are several that buy in bulk to get a very good deal.. I now have the stonework and grading done outside and gravel and stone paths inside, the power is done and ventilation working. Just frosting outside at night but about 60 in there in the mornings, and lots of gaps to seal still. I will post an update on our channel when I get more done! Scott
Btw I have no credentials whatsoever, just farm know-how, which is 90% careful observation and 10% s blind confidence. Build at your own risk!

11:11 if you can utilize a black paint or make a charcoal paste to coat the rocks you'll get another 5 degrees of warmth over night from a couple hours of direct light. A small high intensity discharge lamp such as a 315w CMH would go a long way over night in a space like this as well. Great work.

My father had 6 green houses, and in the spring when it warming up. He make paint, and water in a hand pump bottle. Spray the white wash on top of the glass plains, to block the sunlight in the summer. The rain will wash by fall. The natural gas bill was high in winter, but he placed alot in one or two houses, and closed of the the one's that was used until spring planting. For venting, bring air though 12 inch tube under ground a 100 or 200 feet . That will cool it off in the summer.

So interesting to see the sunken greenhouse done with stone walls rather than concrete…. Given me a real pause for thought as my trade is dry stone wall building, I would say that this would absolutely be possible without the gabion baskets. Maybe the stone walls are good for humidity too? Low tech and lots of natural materials so it’s not hanging round for more years than necessary, what a fantastic project! Great video guys👌

[pinkyfromhaughtfarms]

This is literally my dream greenhouse!

[ja-uhgz]

Fabulous! These videos are so interesting and educational. I love seeing other peoples' ingenuity and creativity. Thank you!

[FireflyOnTheMoon]

I'd love to see an update next year on this. The Gulf Stream makes every kind of difference.

[campingintheforest_]

We went to Bolivia and there at altitudes 15k feet the indigenous people utilize this sunken greenhouse style to grow food, it freezes there everynight. Using this style they grow perfectly well. Was amazing.

[jeffjefferson]

Ive seen people get vents through the ground and have great success with growing citrus fruits far up north. "Nebraska retiree uses earths's heat to grow oranges in snow" is how they did it.

Good looking greenhouse!

Greetings,


Jeff

Started my wallapini about a half year ago. Still have a long way to go because of budget restraints but we're working towards getting it finished asap. Excited. Thanks for the insights and encouragement

[anastasiahedstrom]

I love this episode .
And the couple that are featured ..can't wait to see the end

This has been one of the best season extension videos I've watched.

[YunaOnHome]

Reminds me of how they grew plants on pacific islands in which they had circles of stones around a hole to protect plants from cold sea winds.

I’ve seen a couple guys on YouTube turn their empty in-ground pool into a greenhouse. Tired of maintaining an in-ground pool? Turn it into a greenhouse.

Nice work, I just started digging this year for a greenhouse tucked into a south facing hill overlooking my garden and that 2 tier step down system with an stone internal shoring wall is a good idea. Was just going to make it 12 ft wide with one level, but do have room to go another 6 or 8 ft and split the difference into 2 Tough call, I would have to get rid of my external cold frames in the plan and have much more inside. So many ideas when looking at what people build and for me it has to be a passive heat sync greenhouse, no utilities running out to it except for maybe a couple solar panels and a battery or two for lights. Got time here anyways to figure it out, looks like a 3 year project for me. Hope everyone had a good growing season, it was good here in a zone 4b Ontario, Canada....the pantry, freezer and root cellar are all full, the garden is put to sleep already and there's 2 full bays of compost ready for startup in the spring. Got the snow blower all tuned up and settling in for a long winters gardening 2023 everyone.

[RestorationRanchHealing]

Wow geothermal greenhouse . It’s like a tunnel marries a root cellar . Really cool !
