(I wrote this yesterday, and I thought I posted it, but… apparently not? I don’t know how or why it is in my drafts instead.)
Experiments at horticulture school. (No, we didn’t build these, we just looked at them.)
Built out of steel grids, fleece, chainlink fence and zip ties… (and with drip irrigation inside).
It’s a pity I probably won’t come back to that school for a long time and won’t see how well this works.
