In a cold climate like ours that only gets 100 frost free days a year, it is essential to have effective and affordable food storage systems. Of course fridges & freezers do exist, but root cellars present you with the opportunity to store even more food for less money as you're no longer paying for external energy inputs. And as your gardens get bigger (like ours) you will inevitably need more space for all your delicious pickles, ferments, jams, sauces, and root crops!
This root cellar in particular is exciting because Rob designed it with earth tubes! These tubes run for 250 underground and will naturally heat and cool the root cellar with the goal of keeping the internal temperature and humidity levels in the right zone.
How have you designed YOUR root cellar? Let us know in the comments down below!

Thank you so much for this!!! My dad has unused culvert materials just hanging around and will do a Cobb floor! Wouldn't have thought of this otherwise, so grateful for all the wealth of knowledge you all share 😊👍🌱

@davidrn2473 2 года назад

I am concerned about mold (growing) in the Earth Tubes. I found a new heat exchanger at an auction, retail $1500, bought for $10, (I don't believe anyone knew what it was!) my plan is to use solid earth tubes, and have them go thru the heat exchanger to reduce any risks of mold or bacteria entering.

@matthewkentdavila 3 года назад

install it upside down. NOw you've got a roof and humidity will wick up from the open earth floor

@shackehlicious4687 Год назад

Hi, do you have an update on how it did through the winter?

@seek2find 3 года назад

How do you know how long to make the earth tubes so that they can change the temperature from -40 deg C to +3 deg C by the time it gets to the root cellar?

@amybergman7277 9 месяцев назад

Same question! :)

@fiendeng 3 года назад

easy passive fix for air movement. a large diameter black PVC (2-4") ran vertically high above the seller roof to heat in the Sun and allow warm air to rise , thus pulling cold air in. I'm sure minimal cfm but better than none. add more pipes if one isnt enough. OR construct a pop can heater to move air 😁✌️ excited to see this baby finished

@davidhick4303 3 года назад

Was going to suggest the same thing. Black vertical pipe in the direct sun for a passive solar vent. The only trouble might be the height needed to draw air through his intake piping which is fairly lengthy.

@Isaacmantx 3 года назад

another solution is something similar to what is used in a solar dehydrator... An vertical airtight box with black metal separated from poly greenhouse panels by a few inches facing south with a stovepipe at the top. It would use convective heat to supply the draft, and you could still vary the input air with a manual valve on the intake side. only adjustment needed is cubic inches of draft producing space versus the resistance of the existing soil plumbing.

@sacwriter7400 3 года назад

@@davidhick4303 If the height of the black pipe has to be too long to create enough of a draft, then why not just extend it down through the floor and into the root cellar by a few feet? It's the temperature differential that causes the draft, and the farther down into the cellar the cooler the temperature. You can also increase the temperature in the topside black pipe by putting it in an upright three sided gutter like box, lined with polished metal, and with the open side covered with clear plastic and facing the sun. It's the same principle as a solar oven.

@RockinBarBRanch Год назад

Yes, thank you for the idea as I have a rather large culvert that I will now drag out of the creek, someone else failed attempt to cross a creek

@BearMeat4Dinner Год назад

I think you should build a house or a building around it. It hides it and protects it. Great idea and a great project to take on. Thanks for sharing it with all of us!.

@donnabbb3298 2 года назад

I would recommend stairs rather than a ladder. When hauling jars and vegetables in and out of the root cellar, stairs will make this easier and safer than trying to climb a ladder when carrying breakables.

@007travelbug 2 года назад

Or a dumbwaiter or lift of some sort..? Agreed walking with boxes of jars while climbing a ladder no way!

@007travelbug 2 года назад

What depth do the earth tubes have to be to be effective..(In Ontario here) .. is it based on depth below frostline etc? 4 tubes? How far apart? Thx

@JaredLettau 3 года назад

Are the earth tubes a closed loop (exchanging gases/heat entirely underground) or do they draw in fresh air from distant surface (normalizing temp underground) flushing out gasses?

@nickkitchener6155 3 года назад

Will a black metal chimney work to create a thermal draught similar to how outhouse ventilation works?

@darkhorseeuc 2 года назад

This is exactly what I was thinking. A black pipe extending up a structure (like the greenhouse in the background) heats up in the sun, warms the air inside and convection creates a draft; another earth tube replaces the vacuum in the cellar.

Hi Rob, thank you for your never ending inspiration with you video's and books. As we're living in radon area in the middle of France, do you have a suggestion how to use air tubes in the ground without the risk of radon buildup in the space and the stored food? Thank you, groet, Thijs

@frankenstein3163 Год назад

Nice. What is you summer highs and for how many days ? And did you ever get around to doing it ?

@Patsy-mt3nd 9 месяцев назад

Why don’t you put a ladder Vader in. Takes up a lot less room it’s a lot easier to go up and down by pushing a button. We used to use that invaders to roof houses that was they weren’t that expensive. You could always have the stairs to and the ladder that are running up along it.

@VanillaAttila 3 года назад

What if the water table rises or there's flooding, will the perforated pipes ever draw water into the cellar?

@bountywoodsfarm8594 3 года назад

I think the perforated pipe would be sloped away from the cellar and eventually drain in a low spot if there were one available. So it would also function as a drain to prevent flooding.

@cortneynichols8537 2 года назад

$500 is not "basically for free". I love the concept but $500 is a lot of money for some people (especially those of us trying to have more food security). I'm not at all trying to be rude but just please understand that when you say that it makes everything you do seem unattainable for those who can't afford it.

@leonardorser3455 Год назад

@peterellis4262 3 года назад

It's nice to be able to refer to $500 as "free" and to casually speak of spending thousands of dollars as affordable and cost effective. Tells me more than I wanted to know about your target audience, and I'm saddened by it.

@VergePermaculture 3 года назад

Hi Peter! Thank you for your comment. In consideration of the retail value of a tank like this while also keeping in mind the should-be cost of delivery, $500 is truly dirt cheep, and indeed, basically free. The additional resources required to support the construction of the tank are in fact quite affordable when considered holistically. Consider the savings if you are largely growing your own produce and you have space over the winter to store your root crops and preserves, not needing to spend money on fuel for travel and money on fresh produce over the winter that has been shipped an average of 2,000km to arrive at our grocery stores. The ongoing and long term energy savings through designing this root cellar to be heated + cooled passively. The peace of mind you feel knowing in the instance of supply chain disruption you, your family, and your community may have food security. I do agree with you, this root cellar could not be built for $0. If your budget is tight there are many great DIY root cellar designs out there to fit your needs that I would encourage you to learn more about.

@peterellis4262 3 года назад

@@VergePermaculture I understand all of that Rob. I guess you're just choosing to ignore my point. Not everyone has the resources you're taking for granted here. I expect you've heard some of the discussion that Permaculture is becoming a privileged white person's hobby. Talking about this kind of root cellar construction as being very affordable falls right in line with that criticism and that's probably working out pretty well as a business plan, but it's not very good for Permaculture as a movement to redesign the world.
