I been doing this for a couple years now.
Finally getting around to posting.
Worm are a great way to convert organic matter into fertilizer.
I'm using two types mainly African night crawlers and Red Wrigglers.
These are the Africans:
They have their own house too
The inside
And outside 20 of these 1.5 m concrete rings.
They eat mostly coffee shelling and chopped up palm fronds which we get free.
They also get watermelon and whatever veggies aren't quite up to snuff for the market.
When we prepare a bin we mix in a solution of fresh cow shit. This is chock full of enzymes which helps break down cellulose in the palm fronds making it easier for the worms to eat.
Pics of the finished product later.
