This is good advice.
My worry is that this hydroponics setup probably costs a lot and requires continual upkeep and volunteer labor. Thinking about it, I guess when I say "remains communist" I mean that there exists a community body that is responsible for it, plans for its upkeep (& replacement cost & expansion, etc) and calls forth the volunteer labor to run it. I fear without that ethic the project could devolve into a plain old business.
I don't want to be an individual who goes around soliciting funds and volunteers for a social project, only to have it end up as a rug-pull-transition to becoming a private business.
Advice on community organizing idea, keeping it communist.
I live in a small Canadian village that imports most of it's leafy greens from the US. They're neither fresh nor cheap, and with Trump's new tariffs, people might be willing to consider alternatives.
Here is an idea for a turn-key hydroponic operation I feel could be implemented where I live: https://www.thegrowcer.ca/featured-farmers/filling-a-community-need-valemount-learning-society
I'm looking for advice on structuring/education/outreach for building a new community organization around this idea while ensuring the organization is and remains thoroughly communist.
I assume from your phrasing you mean to say that "some industrialists will prefer human labour over cheaper machines". (But you could instead have meant to say that "in society, there will always be a role for human labour").
I think this proposition is false (in the long run) due to the the profit-maximization logic of capitalism. Even if some industrialists prefer human labour, in the long run they'd eventually be out-competed by those that didn't. But yes, machines cost a lot upfront which could delay the switchover (possibly even beyond the sunset of the industry!).
I think the "Rate of profit falls" theory doesn't matter. Assume it's true: machines lower the rate of profit. But, capitalists can't (as a group) decide not to use machines. Without control of private assets (e.g. capital) the capitalists cease to be, and become a purely rentier class again. It would no longer be capitalism but feudalism. I don't believe capitalists have the power (or desire) to cause such a transition.
