To Geo thermal or not to Geo thermal?


Zone 4b, will it work? Like actually work?

I know what it’s like to invest time and money into something and have it fail, then convince yourself and the ones around it was all worth and totally awesome. Hahaha.

Is that what geo thermal greenhouses are? I’ve seen videos of folks years later admit that they require supplemental heat, and that winter crops almost always die or struggle, and I’ve seen videos of people who just built them and love them and claim they work exactly as advertised.

Is the expense and time worth the odd winter harvest of spinach? Let’s be honest, I can buy a year’s worth of spinach pretty cheap. Spinach using even on my favourite list. Hahah

Thoughts? We get -40 snaps once in a while with weeks at -30…. Like a big chunk of the map.

Someone talk me into this!! I’ve been daydreaming of how to put one in the hillside in my backyard. Empty winter picture attached to showcase the current emptiness and need for something!

TIA

    My family in northern Missouri (bottom of zone 5 top of 6) dug down 10-12 ft, and buried 2-3ft columns that were connected by pipes that then got filled with pretty small gravel. Then the surrounding the columns is a bunch of sand.

    It’s a glass greenhouse, and they have a fan that blows down into one of those columns, then the air travels through all of them, and pops out in the corner of the greenhouse around IBC water totes and a barrel.

    I’m not sure exactly how many columns or how it’s plumbed under the ground, but I do know it works for them. Solar powers the fan, with backup electric if it runs out. The greenhouse never dips below 36 and they’ve had some really cold winters since I was a kid.

    My cousin has had tomatoes growing while it’s 0 outside.
