Small greywater system: a step-by-step guide of how to set up a small greywater system.


At the moment I have two blogs. This is my 10+ year gardening blog but I've also set up a permaculture/solarpunk blog on the new blogging site, Plume. Hopefully once Plume develops more features I'll be able to move off Google, and to there, permanently!

  Small greywater system: a step-by-step guide of how to set up a small greywater system.

With greywater harvesting, you are trying to recycle dirty water, which you may then use in the garden. A greywater system filters and recycles water from when you have been washing up the dishes, taking a shower or bath, or doing the laundry. The system described here is just for greywater from washing up.  Read more

Describing solarpunk: for those new to solarpunk, or looking for ways to describe it

This has been cross-posted from my Plume Solarpunk blog.


If you are new to solarpunk as I am, it might help to have some descriptions of what solarpunk means. So here are a few that I have found helpful, with a link to the full articles where I found them.
 
These aren't dictionary-style definitions. I rather like that solarpunk is still fluid in the descriptions that people have used. Some have a more environmental or artistic focus, others come from anarchist thinking and some combine all three. All describe a more hopeful future, something I find both exciting and comforting.

Descriptions of Solarpunk
*Solarpunk is a literary movement, a hashtag, a flag, and a statement of intent about the future we hope to create. It is an imagining wherein all humans live in balance with our finite environment, where local communities thrive, diversity is embraced, and the world is a beautiful green utopia. Source: Solarpunk wants to save the world

*Solarpunks cherish nature, progress and science; the individual and the community. They believe in a world that is green, colourful, and bright. It can be described as a literary genre, an aesthetic, or a movement. The key points are: an emphasis on renewable energy, especially solar power; a demand for technology and society to re-centre around sustainability, longevity, and balance; a focus on decentralisation, community activism, social justice and civic empowerment; a recognition that economic, social, and ecological injustices are all deeply inter-connected. Source: Sunbeam City's wiki

*Solarpunk is about finding ways to make life more wonderful for us right now, and more importantly for the generations that follow us – i.e., extending human life at the species level, rather than individually. Our future must involve repurposing and creating new things from what we already have (instead of 20th century “destroy it all and build something completely different” modernism). Source: Solarpunk: Notes toward a manifesto

*Solarpunk is a reaction to climate change, inequality, and our cultural obsession with dystopian futures. We want a world where people thrive through energy independence, local resilience, and sound infrastructure…The vision is not about back-to-the-earth survivalism, because solarpunks embrace the responsible use of new technologies like synthetic biology and sensor networks. And it’s not utopian, because the solarpunk future is one that is both high-tech and gritty, and — more importantly — one that we can actually achieve. Source: What is Solarpunk?

*Solarpunks believe that a better world is possible and we can build it in the shell of the old using direct action and mutual aid. We believe in producing for people, not profits in decentralized cooperative workplaces and replacing oppressive power structures with community-level direct democracy. Source: Toot on Mastodon by socalledunitedstates

*Solarpunk is a rebellion against the structural pessimism in our late visions of how the future will be. Not to say it replaces pessimism with Pollyanna-ish optimism, but with a cautious hopefulness and a daring to tease out the positive potentials in bad situations. Hope that perhaps the grounds of an apocalypse (revelation) might also contain the seeds of something better; something more ecological, liberatory, egalitarian, and vibrant than what came before, if we work hard at cultivating those seeds. Source: What is Solarpunk?

*Solarpunk aims to transform science fiction into science action. An emerging aesthetic sensibility undergirds and drives this impulse. As a genre style, Solarpunk’s visual representation is distinctly architectural and infrastructural: while many bloggers emphasize the importance of the “local,” it is necessarily global in concept. Awareness of planetary-scale environmental destruction is precisely where it derives a sense of urgency. In the face of perceived crisis, Solarpunk demands constructive, instructive fictions. Fictions that are not shy about their intended feasibility. Source: Is Ornamenting Solar Panels a Crime?

*We’re solarpunks because the only other options are denial or despair. Source: Solarpunk: Notes toward a manifesto

*You may ask what exactly is meant to be “punk” about what a cynic might see as the lovechild of hippies and futurists. After all, isn’t punk meant to denote anger and rage at the “the system”, as well as black leather and spikey hair? Punk is more of an ethos than a specific set of signifiers, implying rebellion against, and negation of, the dominant paradigm and everything repressive about it. So in that sense, in a world being torn apart by a planetary system based on avarice and power-lust and ecocide, solarpunk might be the most “punk” movement of all. Source: What is Solarpunk?

*What differentiates a solarpunk from an ecosexual, or an ecofeminist technopagan, or an eco-afrofuturist or even a permaculturist? Or, indeed, other colourfully clad, politically oriented utopian movements? Similarities abound, but the focus on the cultural change that will necessarily accompany the full transition to renewable energy is the defining feature of solarpunk. Source: Explainer: ‘solarpunk’, or how to be an optimistic radical

*The solarpunk environmental movement is for anyone who’s digitally inclined but unafraid of dirt. Think post-apocalyptic hacker aesthetics, but with a sunnier disposition. Source: What You Can Learn From the Solarpunk Movement

I don't see this as a static blogpost. If you come across any other descriptions of solarpunk you feel should be included, please let me know in the comments and I'll add it to the list!

Seed viability: will my packet of old seeds still germinate?

L-R: Broad bean, Fennel and Pumpkin seeds

This is an update of a 2015 post. I've done some new searching for seed viability info and have found two more. So I've added those, tidied up the post, and fixed some broken links.

It's the time of year (in the Northern hemisphere) when everyone starts going through the shiny seed catalogues and then get tempted by all the new varieties. Before you do that, it's worth checking whether the seeds you already have are still viable, that is, that they are alive and still able to germinate.

I've cross-checked my previous Seed Viability spreadsheet with any new ones I could find, and have now added Grow your Heirlooms and Fedco Seeds (both from the US) to the list. As you can see, it's not an exact science! It's also important to note that even with the viability ranges listed, seeds can often either fall short of expected viability, or be viable for a much longer period. Much can depend on how they are stored. John Harrison offered some useful advice:
As you probably know, viability is very subject to storage conditions. Consistent, cool and dry being the best. Don't fall for the 'frozen keep forever' - the seed banks like the huge one in Norway (Svalbard) prepare the seeds very carefully before they go to the minus 20 store deep underground - ready to replenish the earth after the asteroid hits or whatever. Just freezing will kill off most seeds as the water in them forms ice crystals that rupture the cell membranes. Incidentally I've sown courgette seeds 7 years past the date on the unopened packet and got 100% germination! Obviously the old car's glovebox was the perfect place...
So view the figures as a guideline. And if you have the time and energy, don't be afraid to experiment with 'out of date' seeds.
