Here are some pics of my latest pit-style tunnel greenhouse, which is around 80' long x 17' wide and has a 4' deep pit. The planting areas have been dug out an additional 2', so from the perspective of the plants, they have an 11.5' ceiling.
It's still very much a work in progress, with a lot to get done before cold weather gets here. Eventually there will be 3 fish pools totaling around 12,000 gallons of water, and I'll plumb the filters so that the poop sludge will drain down into the planting areas to feed/water the bananas.
Here's what the bananas looked like when I moved them in:
Below are a few pics from when I was building it. This time, instead of doing all of the digging by hand with a shovel and wheelbarrow as I had done with my pond and other tunnels, I rented a Bobcat. After the 1st day, I thought, "Eh, that's enough help, I'll just do the rest by hand." Which might have been an okay idea if I hadn't then decided to keep digging and make it twice as big as I had intended when I started.
Here's what the trench looked like after using the Bobcat on the first day:
Then after some hand-digging:
Then after more hand-digging (and more and more and...)
