@tarazkp summoned me and I'd like to say I appeared like a genie, but it might be more like a bad smell...

There are a few communities based around homesteading and off grid living. Some are busier than others. The homesteaders one is run by @jacobpeacock who is himself a bonafide off gridder. Most of the activity tends to be at the @naturalmedicine community, which incorporates homesteading as many of those interested in natural medicine are also homesteaders anyway. I write up a weekly curation newsletter for that community and there is a gardening specific channel in their discord. There is also an agricultural mindset (I think that's what it's called) community.
