I bought a property that has a green house on it. I recently discovered that at one point there were a few others on it. On two of the sites there are these deep holes dug into the ground, within the greenhouse. They are probably 5 ft deep, and 18” diameter. There are two at the corners and then 2 in the middle of the opposite side. (One at the north west corner, one at the north east corner, two on the south side in the center) on both sites. They appear to run from the north holes, south, and from the south holes, north. Possibly connecting? For what possible purpose? In a greenhouse newbie. Any suggestions or areas to look would be appreciated.

Possibly exhaust/air vents for geothermal heating
If there is a set bottom, it might be a dry well, a place to collect water to prevent pooling of water or flooding in the area.
Possibly a GAHT system. Ground Air Heat Transfer. Very good system for regulating temperature.
As said before this is a vent. If the greenhouse was being used I think there would be a grate lid there. Honestly an awesome find. I have been looking into building a green house on and off for the past few years. I don’t rebemeber why but in my notes it is marked as “must have”… I wish I wrote exactly why 🤣

Might be a previously undiscovered observation and escape tunnel system likely placed by aliens…or… a Geothermal system used for greenhouse temperature management. Definitely looks like one or the other. I’m going with tunnels for aliens 👽
Not sure but the first hole looks like it’s full of snakes
