The Worm Guys are trying to develop the Horizontal Flow Through system.

The Worm Guys was Started By Adam Hall and Mark Shaw in 2010 based in Johannesburg South Africa,using Large flow through worm bins to grow Vermicompost. We started off with 3 Kg of worms and have grown them to around 50+ kg and still growing, unfortunately the Flow through bins are quite expensive to build and have turned our attention to try and develop a Horizontal Flow method we first heard about on the Internet in Russia but have never been able to find more detailed method of adding the…

Which worms do you have in your worm farm?

Eisenia fetida, known under various common names such as redworm, and red wigglers, Tiger worms. Theses species of compostworm worm are adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure and cannot live in the earth without a good layer of rotten vegetation.

New Smaller 600 x600mm Home design Flow Through Worm bin

I got fed up with customers who bought Stacking type worm bins loosing interest in Worming because of the effort and time spent harvesting the Vermicast, so we designed a smaller version of our Flow through unit and also improved its design by using steel round bar in place of the Ski rope and using plastic instead of wood for longevity giving the unit up to 5 years life without any need for maintenance.

We are offer the unit for R1700-00 +- $240.00 stocked with worms and already…

Sounds interesting- but anytime I add castings to water (to make tea for instance) they tend to sink. Maybe he dries them alot first?

I'm thrilled to hear about your making them. We have one restaurant here in Honolulu that was willing to have a bin, but I think that's it. Hawaii is way behind on recycling (and just about everything else :-)

Since you're selling them, I wanted to let you know. The fluid that drips out the bottom is called leachate. The tea is made with castings and you have to bubble air through the water to get it to work right. Search those terms and you'll find a lot of info on it. The tea seems to be GREAT for lawns, but I'm in a condo, so I haven't tried it.

Hello Mark!  Wonderful photos, thanks! 

Could you please share more about the "cardboard cakes" you are creating?  I get the cardboard from our local food pantry to prevent it from going in the dumpster and off to the landfill but am having some challenges figuring out an efficient way to use it.  I get it wet, rip it up and use it for bedding and to mix with my feed but it's way too energy intensive.  I've tried a bunch of different ways to get it into smaller pieces as I can't afford a cardboard shredder.  Have thought to providing work opportunities for folks who benefit from such therapeautic activities, i.e. grab, rip, grab, rip:-)

but really like the thought of cardboard cakes and would appreciate learning more.  thanks!

Thanks for the tips on handling the cardboard...i've been keeping my eye out for a cement mixer and this is another good reason to have one.
