I had this show up on my YouTube feed today and found it pretty interesting! i didn't get a chance to check out the rest of her videos, but it looks like she has some good ideas for gardening on the cheap and making gardening a little more accessible.
These are cool bc you could technically make these with almost entirely repurposed/thrifted materials. I like that the raised "beds" are still kinda like a container garden so they are still movable if needed. You could also get a chair with wheels to easily move from garden bed to garden bed to weed, water, and harvest. I also like that the run off from the bigger beds can be used to water smaller containers underneath. I think I might try this out on a slightly smaller scale next year!
