    This keeps composting going all year, right in your kitchen.

      Comments about : Worm Factory®:

      I have been using this for two years now and love it! I previously used homemade tubs to compost with worms and it was messy and a lot of work sorting the worms from my black gold. This system is much easier, neat and cleaner. It will produce as fast as you feed the worms. They are very low maintenance. Sometimes I get busy and do not feed for several weeks and they are just fine! However, production and reproducing of the worms also slow down. I keep in a closet in the garage and in winter use a small heater to keep them warm and happy. Happy worms equals more compost! I do agree with a couple of other reviews regarding the bottom bin. I think the hole should be much smaller to prevent worms going through but will excess liquid, if any, through. I put a thin screen in bottom and seems to be working well. I am purchasing two add on trays today! Getting ready for spring planting!!

        This was expensive but I used a gift certificate so it was a gift for me. I really like it. It is currently outside and I plan to bring it in when the weather gets cool. I hope that it remains clean and not buggy or smelly.

          Comments about : Worm Factory®:

          I've had the Worm Factory for almost a year now. The booklet that comes with the kit is great; it gives a lot of information that I would have had a hard time finding on the internet. Most importantly it describes exactly how to start off- don't just throw a bunch of vegetable scraps and worms in and hope for the best, which is what I would have done left up to my own devices. That situation ends up smelling terrible and doesn't really compost. They recommend mixing the kitchen waste with lots of shredded paper, coir, the perlite-stuff and mineral dust they include in the kit, and either some compost you already have from an outdoor bin, or soil from outside, to introduce more of the decomposing microbes and such.

          I've found that I can put almost any non-meat or dairy food waste in there. Citrus rinds and onions are supposed to be bad, because they're acidic and the worms don't want to go near them. But even those are ok as long as there isn't too much.

          When my compost crock in the kitchen gets filled up, I dump everything into the food processor and chop up and blend it as much as possible. I think that if I have onion scraps in there, blending them with lots of other stuff, it doesn't have a negative effect.

          Initially, I underestimated the amount of "bedding" material needed. Now I add a few handfuls of shredded paper on top every time I add the kitchen waste. I use brown paper bags and the newsprint-paper that's often used in shipping. I always seem to have enough, but if I end up needed more, I'll try trash-picking the newspaper recycling bin.

          Regarding some the unfavorable reviews- one reviewer mentioned the capacity is not enough to take on the amount of kitchen waste their family generates, while another didn't think he and his wife were generating enough food for the worms. I think the benefit of the stacking system is that its capacity is quite elastic- you could just have one tray, or if you are using all 4 of the included trays, you can buy more. I've seen pictures online of this composter with 10+ trays stacked on it.

          I'm a household of one, and I travel frequently during the week, so I don't consistently generate kitchen waste to feed the worms, but that hasn't been an issue. I can say that if you go a month without adding any new worm food, they won't mind. I currently have all 4 trays in use. The bottom 2 are probably finished, and I typically leave them there until I plan to use them.

          I do agree with the review of GadgetGrandma- there should be a layer of some kind at the bottom to keep everything in there. The recessed based below the bottom tray ends up filled with worm casting, and worms. This seems to be where the very best stuff is. Its purpose is to allow excess water to flow out. When it gets clogged up, it doesn't work as well as it could. When you start the first tray, you line the bottom with newsprint to prevent this, and then eventually you put another tray on top of that, without that liner. When the bottom tray is done, obviously that newsprint has composted, and the 2nd tray now becomes the bottom. I'm thinking of building a frame of the same dimension and stretching either a fine screen or hardware cloth to serve as a barrier- something that would allow liquid through but not worms or their casting.

          One problem with worm castings as opposed to traditional outdoor compost, which has nothing to do with this product, is that it doesn't get hot enough to kill seeds. I used some as a part of a seed-starting mix this early spring, and I was getting a lot of things shooting up that were NOT the seeds I was trying to germinate. When I used the worm castings as a top dressing on containers of herbs, and I had a miniature forest of tomato, pepper, cucumber and cantaloupe seedlings.

          I looked online and this is a common problem with worm castings and seems to be inevitable. The consensus seems to be that we need to just not put seeds in there. It was suggested that the finished castings could be heated to reach the temperature needed to kill seeds, while others discouraged this because it would kill beneficial life.

          After seeing how many seedlings (weeds) I was getting, I tried heating the next batch in a low oven until the compost thermometer in the center registered 170 F for a few hours. My logic was that traditional outdoor compost reaches that temperature, so that can't be too destructive to the final product. That batch didn't have any weeds. This was not a well controlled experiment; I'm not sure if I just didn't have seeds in that batch to begin with. Batch 1 might have come from July-September, and the following batch might have been generated during a time when the seasonal vegetables were less seed-y. I will try deliberately adding seeds to a tray, and do a more controlled experiment in the future.

            This was really easy to set up. I just went to my compost pile and filled up one of the bins to get started,added worms & made sure it was moist enough, and that was it! The video is easy to understand, and great information about composting is included! I can not wait until it is time to harvest!

              Have not had the unit long enough to produce any 'fertilizer'. Much more work and attention required than anticipated. Takes much longer to produce results than anticipated. Chopping the fruit, vegetables etc is time consuming and messy. Wife will not help with any of it. Won't allow in the house. Have it in garage. With just the two of us at home, not sure we will have enough food scraps to sustain the wormies. Wish I never purchased it .

                I should have done this years ago. New Mexico has poor soil and is very dry. Last year was a total bust and this year I've tried organic for the first time, and so far it's working fine.

                  Comments about : Worm Factory®:

                  I purchased this unit, and while I am a gardener and outside composter with 55 yrs of experience--I am totally new at worm composting. I wish I hadn't waited--and you shouldn't either!

                  This set-up was so easy as it includes a large booklet & a CD plus everything else needed to set it up, maintain it, and harvest compost. The Gardener's Supply folks will answer any other questions/conflicts in info & there are a ton of online resources & videos. I set mine all up including adding some veggie scraps to start breaking down, then a week later I added 1# of composting worms (not your garden variety--instructions will explain why not). They were chomping away the first day and ever since at an unbelievable rate!

                  I've had no escapes (kept a light on for a few nights), no moisture problems, and NO odors and it's in my house right now! I'm in Michigan's Upper Peninsula & it will most likely only be outside 4-5 months a year due to temperatures. Even up close & personal--it just smells like fresh earth/compost. Not even the scraps smell because you bury them under paper/leaves, etc.

                  This updated Worm Factory 360 model is sturdy, the legs are very strong & well designed for support of all trays when filled, and it includes a moisture drain at the extreme bottom if ever needed for even a small amount of drainage (I haven't had any). Materials are heavy duty, the lid wraps fairly tightly (though is not sealed) over the top and down the side edges for more weather tightness & to stop any escapes. I'll probably put a brick on the lid outside as I'm near Lake Michigan and we get a LOT of wind. Read directions regarding weather/outside locations.

                  Seems the manufacturer (not G.S.) "fixed" the couple of minor issues with the previous model like the inset lid--but the incredibly efficient upward moving tray system remains the same and makes the whole process almost automatic.

                  I love it & am having fun with it, kids will be even more enthralled, and you can know that all your kitchen and much of your paper wastes are going into making your own super strength compost! Even if you don't have a garden or balcony planters--any gardening friend will be thrilled to get this very high quality & expensive compost. It's handling the scraps from 3 people right now in the first tray, and I can see it will handle more than that when the worms & tray numbers increase. It's easy to freeze them if you get a bunch of trimmings at once & then pull them out to thaw when you have a lighter week.

                  For me (a retired school secretary) and I think a majority of people--this manufactured bin will be more efficient, much easier to take care of, harvest, have around, and move--than a big, heavy bin you can make yourself even though for less cost! Yes, the cost is an investment--but Gardener's Supply is competitive on price and has sales & free shipping offers all the time. Remember--you almost always get only what you pay for!

                  I always research before buying so looked at many other worm bins and setups, both manufactured & homemade and asked a lot of questions. In my opinion, this is the worm bin to get and the place to get it from!
