Please consider making a dedicated post for that (or any other similar) video if you find it, sounds like it deserves its own place and that way more people might find it.
Managed to find a copy of Sprout Lands, and reading the synopsis I see 'living hedge' mentioned. In season 2 of Clarkson's Farm (Jeremy Clarkson trying to run a farm) there's a match organized where folks make traditional living hedges, something I had never heard of but found fascinating. So thanks for this recommendation, sounds right up my alley.
I'm currently doing a three-bin system for the kitchen scraps and yard waste (with some added horse manure to get things going whenever I fill up a new bin). That one actually gives me some amount of compost I use in said yard again.
Three months ago I also started a wannebe-Johnson-Su like bioreactor, so a cylinder shaped pile of shredded leafs and wood chips. It's only 80~90cm in diameter and roughly 1m high so nowhere close to the actual Johnson-Su design, but it's what I could make with the leafs/wood and the materials I had lying around.
Lastly I've got a very small vermicomposting setup, a bucket with the bottom cut out and some thick wire going back and forth for the bottom. This is more of a small scale continuous flow setup, which I have not harvested yet. Not too sure whether this thing is gonna work out, to be honest.
I've only been on mastodon for a couple of days, but yes it is active, and depending on what you're after it might we worth it. For me, it seems to be a nice mix of keeping up to date with things and people I already know, and at the same time stumble upon (related) things I did not yet knew about.
You will have to put in some effort to follow people/accounts/hashtags, but that's kinda fun. Just try it out!
