I am new to vermicomposting. Our family generates quite a bit of kitchen scraps during the week but we are limited in the amount of space we can use for worm bins. I have a few 8-10 gallon bins and am using one of these for my 1 pound of worms. I am feeding them about 1/2 pound per day but am throwing another 1 to 2 pounds out in the trash. I want to be able to stack these bins one on top of the other to save space but am not sure how.

Does anyone have suggesting or a website with helpful info on vertical composting?
