Product Description

Color: Green

Worm composting is an incredibly efficient way to convert kitchen scraps, junk mail and cardboard into nutrient-rich compost for your garden. Master gardeners agree that compost produced by worms will produce the best results and help your plants thrive. The Worm Factory's unique stackable, multi-tray design makes it the most efficient worm bin composter around. Worms begin eating waste in the lowest tray, and then migrate upward as food sources in that tray are exhausted. By allowing worms to migrate upward, the worms separate themselves from the finished compost that is ready for the garden. Besides the worm castings that are produced through this process, the Worm Factory also produces a second type of compost. As waste is broken down, moisture filters through your Worm Factory, taking nutrient-rich particles with it. This liquid fertilizer, know as leachate is gathered in the special collection tray of the Worm Factory and can easily be drained from the spigot. Simply add a handful of worms and your organic waste to the bottom tray. The worms will start processing the food. Once the bottom tray is filled add another tray. The worms migrate upward to the newest food source leaving the bottom tray full of nutrient rich compost. As waste is broken down, moisture filters through the system taking nutrient-rich particles with it. You can drain organic liquid fertilizer right from the spigot. It's compact square design gives the Worm Factory the smallest footprint of all worm composters. The Worm Factory's tray stacking system allows it to hold the largest capacity of compost in the smallest amount of space, making it the perfect composter for anyone with space limitations. The Worm Factory is simple to operate. When full, each tray weighs only 12.5 pounds making lifting and arranging trays effortless. The included 38-page instruction manual and instructional DVD makes setup fast and easy and gives tips on how to best manage your Worm Factory composter year-round.

I got my first worm factory about 3 months ago. I am a Guatemalan biologist, but even though I live in the mountain area of Quiche in Guatemala and work in rural development with the local families, the apartment I rent is in a town and it does not have green areas. I was concerned because I produce one bucket of kitchen leftovers per week. I had been donating my organic bucket to someone else's compost pile, but I wanted to do recycling myself. I went into Amazon in Internet and this was my first online purchase ever. I was lucky that a person flew into my country from the United States and brought it with him. It is expensive if you want it shipped, at least for me.
The Worm Factory is very simple to assemble. The booklet is very clear. I bought the worms from a man who is doing organic farming nearby and uses a huge wooden box he built himself, which is about 15 feet long, 6 feet wide and 1.5 feet tall. He is using the manure of his cows to feed the worms and he has hundreds of thousands of worms. Anyway, my worms came with a lot of cow dung but they immediately loved the box, and worked perfectly for the first month with my kitchen leftovers. I was concerned because I had not told my landlady that I would be introducing worms into my place. I did put a little sign on the worm factory that said: "Science experiment, do not touch". I did not have to worry: They are not noisy, they do not escape, and best of all, they are not smelly. I found out the worms love the vegetable leftovers from my juicer machine because those are really finely chopped. They take a lot longer to work through a banana peel. If I let the leftovers "age" about a week, they work a lot better. I was happy to see a lot of dark earth produced in a short time.

This bin looks good in the kitchen, is more than easy to use and my worms are very happy in it. It has large trays so you can keep using it for a good while before paying it any attention (like removing completed compost). The bottom collects "worm tea" which your plants will love and the lid keeps uglies out of sight but is well ventilated for the worms. And it's true: no flies, no stink, nada. Honestly, I will probably buy another one soon (there's always more waste to be wormed!).

I have had worm farms before, but this is the easiest way to actually seperate the food from the castings. You use a system of trays, intially placing the food in the bottom tray, and the tray above it is mostly fiberous material. Then you stop feeding them on the lower tray and then start adding food to the tray up above, and then adding another more fiberous tray.

This system eliminates the feeding the worms in one spot and then pulling out the castings, trying to leave all of the worms in there you can. I like that the worms have more mobility so just in case your feeding area is too wet they can move around. I also like there is lots of air in this system so everything doesn't get too wet.

The tray system was easy to put together, it took only a few minutes. It also comes with your initial bedding of coconut husks. Ideally you will want to put your farm into place, and wet down your bedding, and then get your worms. There are instructions on the top of the lid of the bin to tell you what to feed your worms with, and a great guide that also comes with the bin. I highly recommend this worm bin.

My kids (age 10 and 14) and I have enjoyed the worm composter a lot over the past couple of months. We initially purchased 1,500 worms--each tray can hold up to 3,000. It really does not have any mess or odor, we have no fruit flies, no problems. However, there were a few things that we weren't prepared for when we got it. One is that I had planned to keep the composter outside, but soon learned that the worms can't survive all year round outdoors, even in the heat of summer, so we had to find a place in the house for it. Second, the worms work more slowly than we expected: it takes about 3 months to produce your first bin of finished compost, and food garbage is only a part of what you are supposed to mix in the worm tray. You also must add shredded paper, dead leaves, etc. in addition to vegetable peels and food garbage. This means that with a family of four, we produce a lot more food waste than is actually eaten by the worms. I had envisioned composting our morning coffee grounds, apple cores, and refrigerator "science projects" every single day -- but I am still throwing out a lot of kitchen scraps that I had thought at first, would not go to waste. So I am seriously thinking of purchasing a second worm composter. If I had known this in advance I might have gone with the bigger model right from the start.

update to review below:
After a year...about 3 months ago I finally harvested my bottom tray of compost. I didn't before because there were still lots of worms in it so I figured there was still food in that tray. But I felt like I waited long enough so I put it on the top of the stack and left the lid off and waited about half a day, checking it every hour - the worms at the top would crawl down but I had to keep harvesting the top layer and revealing a new layer to get the worms to keep crawling down. Once they are covered they will stop crawling down so you have to keep exposing them to sunlight. Once I started to harvest the compost I was amazed at how densely packed it was. It was really really rich and heavy soil. It felt like soil that had been smooshed down and compacted.

Also I have now started to more aggressively compost so I put All my scraps in there. Even if it means starting another level. Just remember to put a good ratio of paper and shells in it or they will just rot and attract flies. Putting all my food waste in it has attracted more flies and it smells worse. But I have been putting all my paper from paper shedder in it and now the worms are going to town. They are working fast and moving up to the next tray. I have seen a whole tray of food get processed by the worms in a month and before it took 5 month to achieve that. Just make sure that you are watching them and making sure they are still happy.

Old review still has good tips:
I bought this last July at the Cal State Fair so it's been 6 months. I now have one fully processed tray of compost and one in the works.
