A local supplier discontinued selling biodiffuser chambers, and I bought some at a WAY discounted price.
I used some to get rid of gutter run-off water,, but I still had a half dozen,,
I put them in the garden, they are completely filled with leaves,, the same for the upside down 100 gallon tank.
I had plants started (lettuce, spinach, broccoli,, etc,,) and planted the plants in rows, as well as right next to the chamber,,
So far, the ones next to the chambers are growing twice as fast,,,
I would imagine it would need an entire summer drought to dry the soil under the chambers,,
the soil under accumulated leaves is always damp, and full of earthworms,,, :thumbsup:
So, I hope it will be a giant in-garden earthworm casting factory,,,
