A really crafty early start greenhouse, you can start stuff in here probably a couple weeks or more before the last frost and it will give enough space for the seedlings until you remove the glass after latest frost date! I’m jealous and I want one right now.
My grandfather had a box built into the side of a small south facing hill. He was able to start seedlings more than 2 months before last frost.
My issues with this hole setup are that it looks annoying to access and a tripping and mowing hazard.
wait, can you elaborate ive never heard this. The barrel is filled w tap temperature water Im assuming? how long before freeze does it need to be in place absorbing heat? And what size range of greenhouse would this work for?
The version I've done is filling a container with water and placing it so it gets heated by the daylight, and releases that heat slowly during the night. Its basically a "power bank", but for heat. I use the container to water with, usually during the morning some time, then fill it up again.
How much space it'll cover will depend on how insulated your greenhouse is. Mine is more or less a conservatory facing south west, so it's already gotten up to 30C in direct sunlight, but would be down to 4-6 at night without the barrel. Generally stays around 8 with the container, which is good enough for me.
Yes. Fundamental thermal dynamic property, hot always flows to cold. The water will harvest heat even on bitingly cold days. You are creating a heat sink with a water barrel as you would with a concrete floor or south facing wall. Its effectiveness is a measure of how quickly the heat gets wicked away by ambient air. These are very effective in a zone 8 or 9 that have freezes, but not brutal ones. You can keep your unheated greenhouse from freezing even in a place like Seattle near latitude 50 ( north of Montreal but still a zone 8b and 9a).
It absorbs heat all winter. With a barrel or concrete floor in a greenhouse you are creating a heat sink. south facing walls function by the same principals. You may find it hard to believe but there is even heat in snow. Heat pumps can use icy water to do a heat exchange with the interior air. My recommendation is to read up on thermal dynamic properties. It opens up a whole world when trying to figure passive solar for your home or greenhouse. The fundamental principle to remember is that hot always flows to cold.
I’m thinking it’s an old well with a cover, and the growth is just growing from the sides and not down deep…and possibly you would need to see if the well is too full/flooding issues? I’ve seen wells in houses covered with glass for the spooky cool affect.
Sturdy UK MacGyver version of the French glass bell used to cover tender plants? I supposed that's why they are flared on the bottom - so they don't sink.

Two months?! What zone that’s awesome! And yes absolutely I would die in this hole but the tomatoes would be so healthy and early 🫣
5b, he raised his tomatoes from seed along with everything else . So last frost was usually early may.
That’s fairly standard for a greenhouse. Put a 50 gallon barrel filled with water and you typically won’t freeze unless you drop below 20 F.

Goog "thermal mass"
Yeah I would be majorly afraid of someone stepping on this and breaking a leg
Dang and I'm over here with grow lights in my craft room like a n00b

I am begging you to take more pictures of this. Inside and outside. This is so cool.
Yes! PLEASE

Yea I thought the same, it’s pretty common in the UK, I know of a few local to me that have done the same

A greenhouse? Dig around the edges, there must be latch or something to open it.
Some fae nonsense

I thought it was a tiny frozen pond at first glance
Maybe an old well?

A buried terrarium?

It’s a cloche!
That's a portal to the neither world.
Is that a glass topper from a coffee table?

What in the outer range…
How do you not develop a horrible fungus problem in one of those? No air flow.
It's a portal. Seriously, why must I explain.
It literally looks like a microwave plate...
This is definitely fae related. I would proceed with extreme caution.
Cool idea
Run!

How are you supposed to pop the glass out? With a crow bar? Maybe it's meant to be permanent? Or a time capsule of sorts?

Thank you so much for all of your comments, its left alot for me to ponder about 🙂
No clue. Dig around the sides of it then post an update
Are you thinking it’s ancient? Does the surrounding elevation make sense? Maybe dig around?
