I have leftovers like coffee grounds, egg shells and fruit and vegetable trimmings. Then there is the daily junk mail or paper I have shredded. If it is not plastic, metal, glass, meat products or believe it or not citrus rinds (too slow),then in it goes.
If you have ever done composting outside, then you know it is an outside project. Outside requires the correct amount of moisture, many days of heat, labor to mix and the waiting. Now the worm composting is self contained and the worms do the labor of turning and digesting into compost. The optimal temps are 45 f and 85 f. that can mean indoors in Winter. No smell. I mild weather the worm factory is on the deck, north side under the overhang. Imagine any plastic box in the sun or rain. The worms don't ask for much. It is the extremes that do them in.
The stacking allows the worms to work their way up looking for food and leaving behind the compost for you. The bottom tray becomes the first one to empty and rotate up to the top to be the empty to fill again with the scraps and paper.
The worms used are Eisenia Fetida (red wigglers) this variety is not going to cross breed. If you are thinking about the 'free worms outside', here's the deal, out side they are used to sun and they won't stay in the bins. They will expand their numbers to accommodate the volume of food you supply and slow down their numbers when you slow on the feeding. Start slowly and you'll be fine, remember they are doing most of the work. Think of this like a pet project, but you won't need to walk this one or have a neighbor do chores while you are away. When you are ready for worms, you will most likely order by mail ( check out the free directory www. findworms.com ) first, have the worm factory in your possession. It will arrive via UPS, in a few days.
From start to finish, the recycled food to finished compost will be a few months the first time around, after that, once a month you will be the master of worm composting. Compost shrinks, you have about two inches of black gold Actually, you can take the credit but it is the worms doing the magic.
The worms are looking for bacteria to process, the particles are digested thru the "gizzard" and the outcome is a black crumbly mix ready to mix into the soil. This is so special, it only needs about 1part worm compost to 10 parts soil. Than you have started the microbes in the soil And the soil can heal itself. That's a huge topic.
So are you still tossing stuff in the dumpster? Could it be so easy? The worm factory comes with directions on the lid and written booklet including pictures.
I have referred to compost. Perhaps you have also heard of castings and worm tea. Here's the difference, compost is the process of organic mater going back to the earth. Castings would be more finished, at least 6 months old and probably some egg cocoons. The worm tea most people are referring to is the extra moisture, leachate that falls by gravity to a tray and spout. You could use this diluted on plants, like fertilizer. True Worm tea is bubbled with an aquarium bubbler and water for about 72 hours and then sprayed on plants and soil, it is superrich in the natural nutrients for plants and soil, organic in every way.

Practical, self sorting worms eating your garbage, it is easy and endless fun. You will be paying yourself with the best soil and doing you part healing the earth of the polluting we have all manufactured.
