Just reused industrial food grade shipping containers for a 4 foot raised vertical hugelkultur mound. I molded the outer walls into pockets with a heat gun and chunks of 2x4. Inside is a mixture of old birch, compost and top soil that was ordered. Also 2 of them container a 2 foot clay olla, but I plan to water them from the roof...
Very cool! I can get non potable IBCs for next to nothing, I think they would work fine for something like this.
I have been thinking about making ibc's into sub irrigated planter, your way with increased planting space and also prevent root bound issues.
I've seen individuals use those center pieces you have in there, as active vermipost tubes, throw in some screen, so worms don't migrate into the soil, and toss in bedding worms and food scrap. The vermipost leaches into the soil. If thats not what your already doing. I really like this design, especially the direct roof watering, how do you plan on controlling the water flow? This could be great for urban settings, imagine native flower cubes, where rainwater gardens have no soil, or not far enough away from foundations.
I'd second the idea of in-situ vermicomposting, that would make them into really useful units for people without gardens.
I also think they could be made self-watering pretty easily. Just scale this kind of thing up: https://www.youtube.com/watch?v=-t9gfWhZLEo a 200-300 litre water reservoir at the bottom would make these really hassle free.
Great job, Tim. Those are impressive cubes. I'm glad it was you, and not me, filling those up!
You might want to think about roof water coming from composite tiles. Here's a link that has gathered info from various sources. Might be safer to run it through a reed bed system first, or compost with it. Those tiles are always breaking down in the sun, and if all the water goes into those containers, whatever is coming off the roof will collect in them.
Everything I've read in the past says it should only be used for landscape, not edibles.
I enclosed 3 of the cubes in a small greenhouse along the side of the house. They all got extremely dry because the clay I used could not weep water as intended and the hugelkultur core was too fresh to hold water well. I eventually put a drip line to each cube and then everything was great again. Here is a few photos but there will be many more this spring.
An elephant? An actual elephant. Into the apartment. How is the floor still here. Hold this tiny ad:
