I'm using a 5 foot hole and void covered by foil covered foam then 4 feet of dirt and it is porus enough sandy dirt I draw 48-56f constant. 9 inch fan can draw air out of dirt.
I could in the future yes, it goes down from the fan to about 8’ - 8 1/2’ and runs half the length of the greenhouse coming to the exit pipes, it was very simple design with a lot of labor involved lol. Thank you for checking this out!
@@Earthdwellershomestead thank you very much 😁. That's nice. We plan to do it , but it should work for winter and summer, so we plan to put some exits up and other down, and the fans will work according to the season 😀I hope it'll work .. but yes, the work involved seems to be huge 😅hehhe hats off for you 👏🏼👏🏼👏🏼and once again thanks for sharing.
What growing zone are you in? and did this work over the winter? what were the results? im in zone 8B working on an plan to keep a greenhouse over 45 this winter at night.... love the work so far from what i see tho! this is cool
What state do you live in? How hot do you get your greenhouse during the winter? What methods do you use to heat your greenhouse? What information resources can you share?
Northern Illinois, we keep it around 50f all winter with our four main heating resources, compost, passive, wood stove, and geothermal. If you’re looking to do the same I would suggest researching those topics I mentioned, or just keep watching the channel lol thanks for watching!
I dont know much about solar, but have been thinking about energy systems. How long to the little solar panels last, are these easy/cheap to repair? Any estimates on system kW if we assume 10 year lifespan and 4 months of use/yr?
The mini 5-10w panels last at least 4-5 years as we’ve had one running everyday 8-10+ hrs every day! They do corrode a bit if they get wet for long periods but I’ve not had one fail yet. I bought 4-5 of them and they’re all still working. As far as our new 12v waterproof fan we’re using now I got a two pack for 11$ and it’s ran flawlessly on and off for 6 months or so, that’s why I decided to use it for our geothermal. As for our larger solar system we’ve got 200watts worth of panels running to two separate solar controllers and a timer. Not sure what kW measurements. We use the panels year round also, in summer we move water and air, lights and other items we need to plug in. In winter we use it for heating purposes.
I hand dug after building the greenhouse last fall down to about 7-1/2 feet or so Maby a little deeper. If i was goi g through the effort of digging it up I was going as deep as I could get lol.
You betcha… I wish I coulda found some metal to use but this is what I came up with with what we could afford. It’s still holding. If anything moisture is the biggest issue in summer from condensation
Similar material is used by farmers to drain fields, (draining tile); it handles a lot more soil weight, as well as the field being worked by seriously heavy tractors. The diameter is much bigger but probably a different thickness in pie wall
50 degree air is lower than most people set their air con … so yeah, it feels cold… but the goal w plants is to keep them above freezing

Awesome info
Thanks so much for sharing this!!
Glad you found it interesting!
You need to add panels, not batteries. Usually takes 200 watts per battery to keep them topped off when in regular use.
Thank you mister, it´s awesome ... may you show a sketch of the system of tubes under the greenhouse?. thanks

We’ve experimented with many cheap or free ways for heating. Geothermal is very consistent and reliable. We’re in zone 5a/4b thanks for watching!

How deep did you install the tube?

@@Earthdwellershomestead impressive!!!
Speak up
So do you just have one run of pipe buried?
Nice system. Are you worried about the corrugated drain collapsing? Its not very strimg stuff. Ive certainly dug up some that was almost flattened.
