Where can I find a wooden shelter for my Wormery?
I have a plastic-O-Worms Worm Farm is working well, most the time. The problem is that during heavy rains sometimes it gets wet, and is written in the winter in a can of worms froze very cold and many were killed. Someone I know calculated that one receives wooden cabins (a bit like small scales) fixed in order to maintain the weater Wormery and isolation of the harsh climate. However, I can not seem to find online. Who knows where I can get one in the UK?
I, not everyone who made and will be sold for this purpose belongs. I propose that only the construction of its own. Or just always a piece of wood as big as the tip, and put it in before a big storm comes. I was not going all the time – unless you also add the water itself. In winter, put straw around them. That was enough to get the worms live through insulation is a very cold weather.
