I have watch as many Walipini builds and design video as I could over the years. Your instructions and design is the best I have seen. So happy I found your channel. Keep up the good work!
First time I have come across them and it is an eye-opener to me!
@zpoedog
I agree.
Best walipini video I’ve ever watched.
If you put a house on the back of it the house would be heated by it and the walipini would work better aswell.
We are actually planning that with the build we are currently working on!
@@ADifferentWay There are also video's using compost to heat the 'greenhouses'. In the Netherlands old farmhouses had compost against special designed 'compost' walls that heated the wall and thus the farmhouses using compost. You could do something similar, other idea would be to use a water pipe out of the compost and heat the walapini with that hot water.
Well, now I know what a walipini greenhouse is. Thank you for such a thorough explanation and view into this interesting structure. It gathers together many of the principles I have learned over the years about harvesting solar energy, water conservation, and gardening. Thank you so much for sharing this video.
Gave me a lot to think about! I'm 61 and have built a number of structures for food, but this intrigues me!
"they get drunk and they drown" ruthless!
Extremely interesting project that 28:16 reminds me of once visiting a walled kitchen garden at an estate here in the UK. The huge 200 year old sunken greenhouse used many of the same principles you talk about. The design also included a vast sunken hot bed that used fresh horse manure to heat the space in winter, it was so warm that historically they grew pineapples and mangoes, something that’s virtually impossible to do in the UK climate.
Thanks for your inspiration.
What's the name of this place?
The more I watched the more ingenious I realized it is!
Congratulations on a first-rate presentation!! Your background at the Acadamy really shows. This is one of many ideas i've talked about for many years now. Instead of sending all our kids to college where they accumulate a ton of debt and end up unemployed or working three 10 dollars an hour job to get by, let's offer them these types of opportunities. I can assure you kids would jump at the chance to get out of a classroom and directly into learning a life-altering trade and way of life. You can be sure I'll be hounding our local school boards and elected officials about just that. Thank you for your continuing service to your country.
And being taught there is no God ....when clearly once you've studied the facts ,there can only be God .
@@andrewcorbell7216 Lol don’t drag religion into this, this is about learning a trade and field skills.
@@Negus222 all of which God created. If you don’t like it just ignore the comments…
We took our 5 adopted children out of the school system after 6 months (7 years ago now), to do just this! They are learning the important things in life instead of a bunch of head knowledge. Wouldn’t change it for anything.
School boards care less cause if kids get to learn who would they get to boss
A walipini green house is something that I have on my list for my homestead. I appreciate the walk through and the design instructions.
Oh my gosh! He is the man of my dreams! I love the design & love that he thoroughly understands all the concepts involved! 😊
The best walipini movie I could find. Greetings from Poland
Thanks, and welcome! Hope it inspired you!
That was a thorough analysis of the key points of your Walapini. It belies the sheer amount of hard work and hard thinking you have so obviously put into the job. Thank you so much for doing this.
This is the coolest thing I've seen in a long time. I've never heard of this before. Amazing! What a wonderful feeling of satisfaction you must feel. Congratulations!
I just watched this today and I’ve never wanted to build a Walipini more than now. Your explanation for how to determine the size and direction of your Walipini is hands down one of the best I’ve seen.
Great stuff, very inspiring. Careful with freshly dug trenches. I was told never to get down into a trench without reinforced side walls: if a side collapses, your lungs get crushed by several tons worth of soil and nobody can save you. I used to work for a construction company and my boss said he's seen a guy die that way.Stay safe ;)
Never heard of a Walipini before
Very interesting
Thank You
Hands down then best walipini design I've ever seen. So many designs are horribly over engineered. This design is intelligent, holistic, and efficient. Great stuff - thank you!
THANK YOU FOR YOUR SERVICE!! second, thank you for the tips and info on the build and design!!!
extraordinary design...you have done you homework and applied it correctly...as proven in your success with plants...thank you for sharing ...you can use it to dry wood in summer.
love the mushrooms under the floor idea
This looks like a great Idea. You put a LOT of thought into this project.
Reminds me of some houses I've seen on Earthship Academy
Have you considered running a perforated duct along the peak of the roof, hooked up to a solar powered fan? That way instead of venting the excess heat during the summer to atmosphere you could connect it to your drain and air pipe in the ground and building up the excess heat in the ground for winter usage.
Just a thought.
Very impressive setup
Cool idea.
@@two-sense Not really. Heating the cold sink in the summer won't store the heat for winter, well not really. See the cold sink is also a heat sink, as it effectively uses the entire continental as a thermal anchor, I'm not even joking. For the first few feet, the soil temperature varies by the weather, but by 8 feet down, the Earth is a greater influence than the sky... So any heat transferred to the cold sink is like a drop of water into the ocean. Basically what the initial comment suggests amounts to a solar powered geothermal cooling pump that would diffuse a portion of the absorbed heat, but won't actually save it for winter.
I really like the design! Wow! I’ve been thinking on making a walapini for years. I’m south of you in Texas and my design actually is opposite. I need to escape the heat. Winter barely ever gets colder than freezing. So water tanks are unnecessary on back wall. Instead they need to be in shaded area. Another thing is tubing underground with attached solar fan to circulate hot air into the ground for geo cooling. You could do the same thing below the frost line for the colder months. A gas heater could provide CO2 and warmth. If you put in clay lines and run it hot for a bit before night can keep walapini warm for a while. Run piping under grow beds to keep the plants warm on top and in the ground. Got some great tip to add to mine. Thanks ever so much for putting this up.
Absolutely Brilliant ! having a thermal storage on the back wall is awesome !
Wow- super interesting! I’ve never heard of a Walipini, but it makes a lot of sense! Anyone in Victoria, Australia tried building one? I’d be interested to see what you did and hear how it’s going!
I would have put a small settlement tank before the main tank to ensure no sediment went in
Another good idea and simple enough to design a flush system to drain it out into the cold sink.
I have wanted to build a green house this way for years and have drawn up various designs, but have never seen one actually implemented. I always thought it dumb to use expensive transparent materials on walls that don't get much light, and to not use the moderating effect of the earth to keep the temperature in a reasonable range.
I will have to search Walapini, as I have never heard the name.
Thanks for posting the video it is great to see it really work. If you build another, you should consider using B-decking instead on roofing for the walls. It is a bit thicker metal and deeper corrugations. They use it under concrete in things like parking structures. Of course it costs a lot more, but you won't have issues with the wall pushing in under soil pressure.
I had been thinking about a lean to greenhouse, with a solid north wall with water barrels to absorb solar energy in the winter day and release heat at night. This is a much more complete design than anything I had considered.
While I will not be building a Walipini, I will be utilizing several of its ideas. This video touched upon several points that will help me both optimize the position and maintenance of my grow beds. Thank you and God Bless.
Great video. Very informative and interesting
You mentioned Espalier with your fruit trees, I highly encourage you to follow that path. The history of Espalier all started because they wanted to train fruit trees against a thick wall that would absorb the heat to keep oranges and other fruits as warm as possible throughout the year in France. The flat designs of Espalier aren't just fancy looking, they're done to keep the plants as close as possible to the wall behind them and benefit the most from that thermal mass.
If you experimented with some hook magnets you could probably find a perfect option to train your plants/trees directly to your water barrels without needing any additional support structures. I haven't seen it done before but they'd be infinitely adjustable in placement and you could find different holding strengths in different magnets.
This has evolved my idea for a thermal type of greenhouse I've been planning for my garden. Some fantastic information and ideas that I'm certain I can incorporate. One idea that I've had looking at your plan, the glass on the North facing roof that you cover with insulation in the winter, what if when you take it down in the summer, you store it in front of the water barrels? My thinking is it solves 2 issues, firstly it further helps deflect any heat from the water barrels, which don't want in the summer, and secondly storage, those panels have to go somewhere during the summer, and I would need an answer for my wife where that would be. I love this, thank you for sharing it with us, is perfect in everyway for what I'm wanting to do, possible Denmark's first Walipini.
I was just thinking he should put some reflectors inside to increase the light, this would also solve that problem 🤓
This is a really informative video. I love seeing the cross section map of the design as well as the tour. Thank you for sharing!
You did a great job explaining the orientation, cheers for that
Excellent, excellent resource. Thank you very much for sharing this. It addresses the real nosebleeds in most greenhouse designs by keeping solar insolation, thermal mass, insulation and ventilation as top priorities and letting them dictate design. Thanks again
Thank you for this tour! I have looking at trying to extend the outside gardening season in Wisconsin. The research in the roof angles, sun exposure and venting were very informative. I have been looking at smaller gardens, digging down so you can stand up inside is brilliant! The comments about the thermal heat from the water barrels below was also helpful. Going to review this video again.
I love the engineering thought and experimentation involved in the project. Definitely something I will try on my own property! Thank you for sharing it!
My grandfather had a sunken lean-too greenhouse in Aberdeen Scotland and used to grow wonderful tomatoes and begonias, as I recall. Not quite as scientific, but it stored heat in the back wall (granite) and insulted with the ground in front - probably 3 to 4 feet high. Possibly a less cold winter (usually) due to the proximity to the sea. Your walipini sounds a good development.
this looks like a very nice and efficient setup for dealing with temperature extremes. Hard winds can be an issue for greenhouses but this one seems fit for the job. Thank you for sharing this with us ... really appreciate it !!
Exemplary and very impressive!
Nice job, well done, farm simple. Looks like if you use did it again a nice addition to the roof would be foil backed insulation for added light bounce from fall to spring.
Perhaps you have already looked at article " Man grows oranges in Nebraska in the winter"
Russ Finch Is The Man!!!!!!!!!!!!!!!!!!!
Excellent video!
I watched it a few years ago. Great idea!
Yes! That was another fascinating work in progress!
Citrus in the snow ❄️
Ingenious! Love the whole idea. I've been in love with passive solar since the 60's, but love your added geothermal ideas. Wish we had room (and $$$) for something like this, but I think I will incorporate some of these principles into my greenhouse plans. I am in NC, so not as much threat of freezing, but we have had below freezing mornings most of the past 6 weeks (Jan & Feb). Thanks so much for this great video!
What a great way to harvest the maximum amount of sun and heat for all seasons!
You describe this SO well! Thank you for sharing! Wonderful job!
I wish I could roll back the clock 60 years back, still it is is exciting to see someone with success.
This was a great video. Thanks for sharing it. I've been wanting to build a bermed greenhouse for a while and you rekindled my enthusiasm with your video. I think this is my next big project for a south-facing slope here at our house. Thanks so much!
well ....u just made what i've been thinking through and about for years ...i had many doubts bout materials to be using ....glad to be able to see your design about this ....nice details with angles of sun hiting barrels by seasons.... wreally nice...
This is great. Plus it’s great to know how to figure it all out! Reminds me of earthships and solar passive. Smart!
Regarding your aphid problems... I live in a flat in the UK and grow a lot on my lovely balcony - vine-tomatoes in pots from macrame-holders along my washing line - but the season isn't long enough for peppers, which I grow indoors in large pots on a windowsill.
I stood smaller pots of mint upon the peppers' soil, amidst the plants, and I ruffle the leaves occasionally - in ''double'' pots, actually, because mint is a very thirsty plant, wildly invasive, and other plants don't like their root oils - so I put the mint's growing and drainage pot inside a solid-bottomed, slightly bigger pot, which does get a bit mucky after a while and needs cleaning... but it drastically reduced the aphids, not completely - they seem to huddle in specific areas now, where i grab them with tissues - but what an improvement.
Thanks for the great video and G-d bless.
Excellent video. Thank you so much.
This is a very good overview! Thanks very much for the detail, diagrams and specifics. The work is excellent!
It is absolutely true that this design is latitude specific. There is no one design per se, and you have to adjust it for not only latitude, but also conditions.
Deserts and semi arid is where this technology can shine year round. There, you can't grow much of anything in the high summer, as temps go over 100F. You'd have to alter it to be able to do serious cooling in that time, using earth tubes extensively, or geothermal cooling, as well as misting.
any way to unchunk and approximate the $investment/spend up front?
This is the GREATEST thing I have ever seen. I'm serious. Starting construction in April.
Are you up north (U.S. or Canada)? Will you be posting your build and grow updates here on YT?
so awesome! this is my favorite design so far, really enjoy you worked the solar battery water barrels in combination with rain water catchment together.
I laughed for a long time after your intro.
Love this video. I've been watching Russ Finches videos for years now preparing me for my future design. You however made this more of a reality for me in that you explain so much of your design. It's different but I like some of your ideas better. Thank you so much for posting. I hope to start constructing my own this year.
Great presentation!
Very clear and concise.
Thank you all.
Ingenuity on a heroic scale. Bravo.
I love the idea....the best part is your info brings to light a way to improve it
Absolutely love it! I am subscribed and can't wait to build my own.I would definitely spend the extra money and make the load bearing and underground walls from reinforced concrete for strength and longevity.....thank you so much for sharing such detailed construction information and also for critiquing your own work. Thank you thank you thank you from Australia
I recommend using ICF insulated concrete forms.
Thank you for your detailed explanation of this structure and its functionality. I’m in awe of it. We live at 7100 ft in elevation and have struggled to determine a good way to establish a garden.
We first learned to garden at that elevation! We lived out east of Colorado Springs, between 7000 and 8000 feet altitude. It was a challenge for sure! We had a friend who was an incredible gardener in the area. He said the key to outdoor gardening was using cool season, fast, growing vegetables. The key to the longer, warmer season vegetables Was some type of greenhouse or other protected structure that could provide supplemental heating when necessary. He had that, and he had amazing tomatoes even in fall! We would’ve loved to pursue the idea of a walipini, but where we lived at the time would’ve required a mountain of expense and paperwork to dig the pit. So we waited until after we moved. But it would definitely be an asset in that climate!
Thank you very much for showing us your design and explaining your reasoning. I really enjoyed the very well structured information! ♥️ We will definitely consider some of the mentioned aspects in designing our grow house.
Какая продуманная конструкция, молодцы!
This is ingenius! We can get minus 5C typically. I have cacti I let dry in the twinwall polycarbonate-roofed greenhouse for the winter but to keep a few other things survive I use a single paraffin burner. I am just about to go out and light it before bed since we expect zero C or lower, tonight.Last year I just covered evry bench with a double layer of newspaper from November until early March, and to be honest I believe that worked better than this current regime is doing. I love how you have thought it all through scientifically. Well done on the whole project! Thanks!
Very good setup design, well thought out.
The winter crops you isn have would fill your walloping hut and have lots of things.
You can literally live off of plant leaf green juicing...And throw carrots in it.
Huge props to you! This is so cool.
Fantastic. Would love to build this someday
Awesome. I'm thinking wood chip/compost heat is easily incorporated with a trench along the back wall and/or roof. Empty the compost trench in early summer. This will allow better cooling in summer, too.
It would not be hard to incorporate a static pile compost outside, maybe on North berm area with coiled PEX built into it and then run that through the Walipini in a loop with small pump that could be turned on and off by thermostat. Give an additional source of heat in depth of winter, use the compost inside and outside on beds in spring, rebuild the pile in summer and fall. I saw a great static pile set up heating tomato beds inside a greenhouse at McEnroe Farms, Amenia, NY USA in 1990 or so.
Incredible presentation, thank you so much for every detail.
A fantastic implementation. I've th5a out a walapini for years and you nailed it. Thank you for your tedious insight as it is greatly appreciated.
that was a great presentation
He said bonne appetite😆..dig a hole and figure it out..I like that..😊
Genious. Instruct mayors and farmers. Congratulations.
Very thoughtful design.
Huge hugelbed love them
Thank you for sharing your work and info. Not sure why UA-cam is so slow to suggest videos on them. They’re great!
Thank you! One of the reasons we are hoping to hit 1000 subscribers soon is because those videos are seemingly able to reach more folks. So please help us spread the word! Thanks for watching.
The most comprehensive presentation on UA-cam. Thank you. A lot of info. I can do this.
Thanks and glad you found it helpful. If you are considering building a walipini, be sure to check out our book, which can be found in the description of the video. It includes far more details and information Then we could put in the video!
That is the most beautiful aloe I've seen!
This is incredible! I am wondering how you keep the water abundant in the winter- don't the gutters fill with snow/ice and stop adding water until the spring melt?
It’s actually easier to keep the barrels full in winter than in summer. As the temperatures cool down, soil evaporation slows tremendously, thereby decreasing the need for water. By December, we only give a light watering about twice a month, and by January it’s only once a month. Our region tends to be very cloudy during the winter, and we also have several warm spells that melt off any ice or snow allowing our barrels to refill.
@@ADifferentWay thank you for the informative and super quick response!
when NASA goes to get the groceries
Thanks so much for sharing your designs. I really appreciate your effort. Great job!
I have known of the walipini for some years now. I believe everyone should have one. I will be putting one together in the near future.
This was a well done, very thorough, well thought out video and awesome explaination of a walipni.
Cheers
I love this. Several concepts I’ve never seen. For example, the cold sink I found totally counterintuitive but fascinating.
Have you considered making the insulating panels on the roof white on the inside? I’m not sure if there’s a reason for them being black, but if not, the white would reflect any light that hit them. Not sure how much more efficient it would be but even simply from a human experience perspective, it might make it feel brighter/bigger.
Thanks for your contribution! =)
You are right, white could definitely have offered some advantages. In this case, we only had black because we bought them used and they were very inexpensive! 😁.
Black absorbs heat.
I was thinking about a lean to greenhouse with the barrels and the north wall painted black to absorb solar energy in the winter and a white or metallic screen to block heat from absorbing in the summer. This design looks much more efficient than anything I had come up with.
@15:40 dog is looking around thinking who is he talking to? 😅😂
The big joke around here is how she somehow manages to get herself into EVERY SINGLE VIDEO! 🤣
Absolutely the best tutorial I've seen! Thank you!
thank you for your service like the video have a great day
With the high cost of wood right now this is only a wish.....
Very informative. Thanks for sharing.
Your Walipini is brillent and a good design, it would even be a good design for a winter house, thanks for the video much appreciated
Incredible planning and design. Thanks for sharing 👍
Well done video, thanks. As you were describing the process and materials I was trying to come up with a cost estimate in my head. I know material costs vary depending on barter and purchasing new, could you provide a rough figure on cost?
Like you said, it really varies with how you source your materials. In our case most of the lumber was rough cut, from our own woods, on our personal Lumbermill. The barrels were sourced used for $5 each. The topsoil was left over from a friend, so our main expense was the twin wall poly carbonate glazing, which ran us around $2600. We also had to pay to dig the trench, but we packaged that in with other excavation work we were doing at the time. So it probably cost us around $800 or so. Then there was hardware and just some miscellaneous items. I think our grand total actually spent was around $4000. If we had had to buy all the lumber, it would’ve been at least twice that. Hope that helps.
@@ADifferentWay That does help, thanks. I hope others appreciate the detail that you provided and thought provoking comments.
@@ADifferentWay if and when you do this again do you anticipate cost savings?
Now that I know it works and more than pays for itself, I would actually invest more. Additions would be a footer for the tanks, a cement front wall, and a subterranean air flow section to utilize more ground temperature stabilization. I think a combination of this and Rush Finch's design (Greenhouse in the Snow) would be ideal.
What exactly would you do differently if you had to do it over again?
First, a really well reinforced front wall. We knew when we started this project, that we would eventually wish we had done that, but we intentionally built this as kind of a prototype and cut cost in that area. Another thing we would do is add far more ventilation pipes underneath the grow bed to circulate air better. We don’t have good enough airflow in the heat of summer to cool it. We would also invest in better topsoil for the garden. We got what we were told was topsoil but wound up being black clay that has been a curse ever since. Finally, we would put an actual footer under all the barrels, as we have issues with them settling and tilting, and we have to reset A couple each year.
I wondered if another eaves trough along the south side would have kept the water from draining down the panels and making the dirt in front collapse. Also, is the size of the walkway imperative? Could it be built to accommodate a wheelchair’s width and height for a seated person to work in the beds?
Because the roof is angled to the back, water does not spill off the front. Our particular issue is the fact it is located only about 8 feet from our driveway, which is consistent pressure, and the 8 feet in between is heavy clay soils that become water-logged at times. As stated, we knew this would eventually be an issue, but our goal was to build a prototype that would last about 10 years. The walkway could easily be made to suit a wheelchair. Just be aware that the wider it is, the more the square footage increases, and that in turn increases the air space that must be heated and cooled. Depending on your zone, this could be used to your benefit, or could require a little creativity! You could decrease the height of the grow bed by raising the level of the board path, but still allow for a good cold sink and good air flow.
Ever since we got it dumped, and realized how much clay was in it, we have been working to amend it. We add compost, sand, and other amendments about twice a year when we prepare to replant. We have added thousands of worms. We grow lots of root crops to help break it up, as well as use our broadfork. The soil in the walipini is some of the best we have. It's just a process, as you say, that can take years. We still find "chunks" of clay each time we start planting, though!
Super videó információ .Köszönöm szépen. Jó EGÉSZSÉGET KÍVÁNOK.
Excellent project and even better presentation, thank you very much for sharing your knowledge and experience with us!
What is your growing zone?
We are on the northern edge of 5b.
Wow that’s impressive. No supplemental heat.
Good thing "they "dont teach this in schools or we would be free ,the government biggest fear is fertile ag land and people who know how to use it.smart brother!!!👍
I teach this. California elementary school. Been part of the curriculum here since I was a kid. Catch the hell up, America.
Hey, excellent video. Thank you.
Kind of a way to get around shed/ outbuilding height restrictions. I'd never have thought you could have a two storey garden shed.
Thank you for the video! I had heard of the walapini and some of it's benefits, but you definitely shed new light and presented some great tech aspects. I'm looking forward to trying it out here in Oregon. All the best to you and yours!
Impressive water system! Thanks for sharing your experience. 👍
Well I'm just in the process of building my first greenhouse conventional style then I come across this, makes so much sense
Back to the drawing board
Great idea and if I had the room in my Toronto city garden, this would be the project I would tackle. Well done and thanks for sharing.
So impressed with your project! Well done.
