Can we not just get rid of the traffic instead?

Tried to grow them in our greenhouse and failed. (Scotland)

No idea where to buy them, just pointing they’re quite hard to grow here.

Yeah, we move ours into our glass house over winter. I also made it an insulated jacket out of plasticky padded envelopes and duct tape 😀

It’s come through temperatures of -7C that way. The worms will all go deep and huddle to stay warm.

I’m assuming a worm farm is what we call a wormery in Britain. The main thing about wormeries and bokashi is they can take cooked food waste, that’s not usually advised for composting.

So in part I think it depends what your source material will be.

Our wormery can get a bit whiffy, though it’s not noticeable until you take the lid off to put more stuff in. Still, not sure I’d want it inside. Bokashi seems designed for indoors.

Every couple of weeks during the summer, once a month over the winter. Used to do it weekly, but decided I should probably let it heat up more between turns.

I do it by getting a fork and properly turning and mixing it. Very physically demanding!

I only really have the one 800 litre bin though. I think the let it sit strategy works better when you have 2 or more, just layer well and let nature do the mixing!

Ours go into the recycling. Not sure what they get recycled into. Have a vague memory of them getting shredded and mixed with resin to make insulation boards.

I live in Scotland, so no where near that cold or much snow. But making sure it’s got the minerals to keep microbial growth going should help it generate it’s own heat. We can buy a product called rock dust here, it’s ground up volcanic basalt - side product of quarrying - wide range of minerals in it. Mixing some through before covering it should help.

Another thing that gets it cooking is wood ash, needs to be a pure wood fire obviously. You can also go the extra step and make biochar to mix in - you’ll get some ash with that anyway.

If you live near the coast a bit seaweed is a good addition too.

I try to turn my own compost regularly and it’s gratifying to see the steam rising on a cold day 😁
