Flow Through System: How optimum tall of each worm bin?
My worm bins are made from wood material. I follow Pauly's video "Setting up a worm bin using a wooden flow through system" at https://www.wormfarmingrevealed.com/flow-through-worm-bins.html.
I want to ask about how optimum tall is the worm bin?
First, I made it with 9 cm (3.5 inch) tall and after several months, the castings are too much (I think) and too compact. The bin is heavy when I lift.
So, I made a new worm bin with tall about 4 cm (1.5 inch) and I still wait the harvesting time.
Now, I need some help from experienced worm farming like you Pauly and others.
NB: the long and wide of my worm bin are 45cm x 45cm or 18inch x18inch
