Customer Questions & Answers

I would like to know if the chambers are able to be disassembled, such to carry it easily. The containers seem to be too big .

Could you please send some photos of a composter not assembled?
Asked by: Mariale
The chambers can be disassembled, but it's very time consuming... and then you'll have to assemble it again, which is no quick task. If you're transporting the unit, your best bet is just to take the legs off and move the whole thing.

Can I compost cooked oat meal leftovers and cooked lentils? How can I check my compost is working?

Hello, I have only had this since Sunday- for 3 days and I can see the compost is not happening. It is not heating up and it is starting to look like rotting food. I added dried leaves to the kitchen scraps. I also added the organic compost starter that I purchased. Please, any advice would be helpful. I need this to work! It is only attracting flies so far!
Asked by: Teo
I hear you--composting is a skill requiring knowledge, patience & a learning curve. Found this and think is informative, comprehensive, but simple to use. Hope you feel the same. Good Luck!! GENERAL The Tumbling Composter contains a mechanism with rods or fins that mixes and breaks up larger clusters to activate and accelerate the decomposing process. Such composters are able to reach a temperature of more than 140°. In order for compost to be efficient, it requires a correct mixture ratio of "brown" (carbon# and "green" #nitrogen# materials #see LIST OF KEY COMPONENTS FOR GREAT COMPOST#^ Water should be added only when necessary and the tumbler should be turned every other day or so to keep all ingredients, microorganisms, and moisture evenly distributed^ Within a few weeks, your Tumbling Composter will transform your scraps into this natural fertilizer named compost^ COMPOST CAN BE PRODUCED WITH YOUR TUMBLER IN TWO DIFFERENT PROCESSES: 1 The best method: Produce compost in batches, loading up the tumbler until full, and leave it to break down until completed^ When running two tumblers simultaneously, one can start adding waste to the second tumbler and wait for the first to complete its decomposing process^ Refraining from adding more materials to the current batch of working compost will ensure better results^ A batch with new waste materials can then be started when the first is completed^ 2^ Another method is continuous composting, where one adds more and more material, mixing fresh waste into the decomposing process^ When choosing this method with the tumbler, one should stop adding when it the tumbler is almost full, and leave the contents decompose^ Only after being completed can the process be started again^ LIST OF KEY COMPONENTS FOR GREAT COMPOST Decomposing Process – When trying the process for the first time, it may be surprising how many small creatures are participating in decomposition^ This mixture of creatures, which include many insects, bugs, slugs, bacteria, and mushrooms, form what is called a "food web^" Adding a small quantity of soil to this mixture can be used to start the process^ The creatures in the soil will actually contribute and speed up decomposition^ Each and every member of the food web has its own contribution to your compost and it must be left alone to do their job^ If any of the member organisms is removed by using agents such as pesticides, the natural cycle will be disturbed and the compost will be infected by pesticides^ Ingredients - Basic ingredients for composting are: nitrogen, carbon, water and air^ Water and air should be readily available^ Providing the remaining ingredients is somewhat more complicated^ They are actually referred to as "greens" and "browns"#not meaning the color but green = rich in nitrogen, and brown = rich in carbon#^ The "green" ingredients represent the protein for the active creatures, and the "brown" ingredients supplying the energy^ Any plant in your garden can be used to "feed" these creatures^ The tumbling composter should simply be filled with these ingredients and mixed^ Water must be added separately and the whole must be tumbled to add air^ The composter should then be left alone, to let the decomposing process take place^ Nitrogen / Carbon Ratio - The ideal mix is 3/4"brown" and 1/4"green" ingredients by volume^ Such a good mixture of "brown" and "green" ingredients will ensure for the mass to maintain the appropriate quantity of humidity and air, and fasten the decomposing process^ An increased amount of nitrogen will generate a heavy mass, which will slow down the decomposing process^ Then may be the right time to add more "brown" ingredients! Nitrogen-"Green" ingredients range from lawn clippings, green leaves, manures to garden trimmings and are ideal sources of nitrogen for composting^ The same can be said of kitchen waste, such as vegetable and fruit leftovers, which also generate nitrogen^ Kitchen wastes are usually kept in a plastic container under the sink^ Before using them as ingredients for the composter, cut up the larger pieces before use^ Carbon - "Brown" garden ingredients such as dry leaves, twigs, or hay provide the carbon part of the mixture and will ensure a lighter and aerated compost^ Carbon is best provided by using dry leaves^ Dry leaves can be collected, shredded, and stored to be used all year round^ If the mixture gets too wet or contains too much nitrogen, add dry leaves^ #Refer to BASIC NITROGEN / CARBON CHART for more detailed information#^ Water - A common mistake during the composting process is neglecting humidity^ The compost should remain humid all along the process^ About 50% humidity is acceptable^ How can we make sure that such humidity is achieved? One can simply open the compost tumbler, grab and squeeze a handful of material in your hand; if a few drops of water are released, it is most probably humid enough, if not, water should be added by inserting a hose deep into the mixture so that not just the upper layer will get wet^ Let excess water drain out through the ventilation bores^ The mixture should remain humid, but not wet^ Air – All creatures and mushrooms in the compost mixture need oxygen during the process^ If the mixture is too dense or get too humid, the air supply into the mixture is prevented and the laboring creatures will probably be exterminated^ The process will slow down and a nauseating stink will start^ To prevent this and fasten the process, the tumbler must be rotated every second day or so^ This would also be a good time to add shredded leaves from the stock pile^ Preventing moisture can also be achieved by opening the composter lid for a few hours^ Don't be afraid to make mistakes during the process, you will learn from experience^ It would be a good idea to write down these experiences and keep some records; they might come in useful in the end! Refer to TROUBLESHOOTING for more detailed information^ NOTE: The decomposing process has a lot to do with the surface area the tiny creatures have to operate on^ The best results are achieved when individual pieces in the decomposing mixture are kept small^ Cut or shred larger ingredients into smaller pieces^ A lawn mower can be used to shred dry leaves when no shredder is available^ MATERIAL CARBON/NITROGEN INFO Table scraps Nitrogen Add with dry carbon items^ Fruit & vegetable scraps Nitrogen Add with dry carbon items^ Chicken/rabbit manure Nitrogen Excellent compost 'activator', use in moderation^ Coffee grounds Nitrogen Filters may also be included^ Tea leaves Nitrogen Loose or in bags^ Grass clippings Nitrogen Add in thin layers so they don't mat into clumps and putrefy^ Garden plants Nitrogen Use disease-free plants only^ Lawn & garden weeds Nitrogen Use only weeds which have not gone to seed^ Flowers, cuttings Nitrogen Chop up any long woody stems^ Seaweed and kelp Nitrogen Rinse first; good source for trace minerals^ Eggshells Neutral Best when crushed^ Leaves Carbon Leaves break down faster when shredded^ Straw or hay Carbon Straw is best; hay #with seeds# is less ideal^ Pine needles Carbon Acidic; use in moderate amounts^ Wood ash Carbon Only use ash from clean materials; sprinkle lightly^ Cardboard Carbon Shred material to avoid matting^ Corn cobs, stalks Carbon Slow to decompose; best if chopped up^ Dryer lint Carbon Best if from natural fibers^ Wood chips Carbon High carbon content can overwhelm, and shut down, an otherwise good compost batch; use sparingly^ Sawdust Carbon High carbon content can overwhelm, and shut down, an otherwise good compost batch; use sparingly^ Be sure sawdust is clean, with no machine oil or chain oil residues from cutting equipment^ Do not use sawdust from painted or treated lumber^ AVOID ADDING THESE INGREDIENTS TO THECOMPOST MIXTURE: Meat, fish, fats and bones - These could ferment or putrefy, causing odors, and attracting flies, rodents or other animals that can be pests^ Other foods like dairy products, sauces, salad dressing, and cooking oil – These can ferment or putrefy, causing odors, and attracting flies, rodents or other pests^ Paper products – They may contain chemicals that are bad for your compost^ These should be recycled Ashes -Wood ashes maybe very useful but in small quantities^ Never add BBQ grill ashes directly into the compost mixture^ Dog and cat feces – May cause a risk of adding diseases! Moderate amounts of chicken, horse, cow, and rabbit manure may be fine^ Perpetual weeds that have turned to seed or diseased plants – Not to be used as they can spread with the compost^ Any cooked or canned foods that contain salt - Salt kills the little creatures that do the composting in your mixture^ Important: Do not add any part of the Black Walnut tree; it contains a chemical that may inhibit the composting process^ TROUBLESHOOTING Odor Too much nitrogen=Mix in "brown" material and rotate tumbler Too much moisture=Lack of oxygen The Mixture Does Not Heat=Up Lack of nitrogen Mix in "brown" material and rotate tumbler Lack of oxygen=Rotate tumbler Lack of humidity=Humidify mix Too much humidity=Mix in "brown" material and rotate tumbler Particle size is too large Cut or grind materials Attracts Animals/Pests=Mixture contains bones, meat, or fatty foods, or animal manure AVOID ADDINGTHESE MATERIALS TOTHE MIXTURE. #See AVOID ADDING THESE MATERIALS TO THE MIXTURE# For more info: Search for online & open the instruction for miracle gro tumbling composter TC100 instruction manual.pdf [however you can get it to open]

It's holding up beautifully and works really well once you get past the learning curve of composting. My biggest tips for this particular composter are that compost starter is your friend, and so is the SUN. Heat breaks things down faster, so putting this black beast in the sun really speeds up the composting process. The first couple of years I had it in a shady spot and it was sloooooooooooooooooow going. Like, it took ages to get anything out of it. But now I have it in a sunny location, add a little water regularly (I live in a warm, dry climate), and now we're in business. The "weeks" claim is still a bit optimistic, but a couple months and you've got something. Criticisms? It can be a little difficult to turn, especially when fully loaded. Some sort of handle that protrudes would be easier than the depressions for grip. And the depressions, if not hosed out regularly, become bustling nurseries for pods of black widow eggs in my area. All in all, though, I love this thing, and it remains the longest running, most fun science experiment in our family.

Rated 5 out of 5 by from Correct website for instructions The link for the detailed assembly instructions is broken as of the time of this review 4.9.17. I did find them here I am a 41 yr old female with fibromyalgia and was able to assemble this by myself in about 90 minutes. You need a Flathead screw driver and a wrench. You only need the wrench on the stand. First assemble the stand. Then move onto the panels. The 2 side octagon panels have 8 edges and one edge has 7 holes. This edge is where your door goes and you must add the door panel very last! So start moving counter clockwise adding panels. Just add a panel, put in all the screws, making sure the little tabs are in place and the center divider is in place. Then continue working counter clockwise until you get to the door panel. Very simple, just a little tedious with 56 small screws. Excited to get started composting. I looked at some various little containers to keep kitchen scraps in until I'm ready to take out to my composter but decided just to keep a plastic container in the freezer to add them to. That's my tip! This composter is a bit small but I'm an amateur. I will start with this and if I find it's too​ small can always upgrade. I think this will work quite well. Bigger isn't always better! This one will be manageable for me to use and turn by myself.

Rated 4 out of 5 by from Not bad Bought this dual chamber composter last fall. First time composting. Took about an hour to assemble . I added greens and browns. One chamber got full pretty quick. Within a week, i was able to add more to it. Winter was approaching so composting wasn't happening fast enough. Started filling second chamber. Ran out of brown leaves to add and started adding shredded newspapers, egg carton and cardboard. Both sides were now completely full with composting almost to a halt with freezing temperatures around. Composter was left alone for the winter. Unable to turn unit around, as access to it was impossible with the backyard having three feet of snow. It was just a few weeks ago that I took a look inside the unit and found that each chamber had half amount of compost. Nice dark brown of compost had formed but the cardboard and newspaper had not really disintegrated. It was just a lump of wet newspaper. I'm hoping as the weather warms up, decomposition speeds up. Not sure if I would add newspaper to this composter. It is hard to turn the heavier it gets, so I would most likely half fill one side, before starting the other. Overall, nice composter. Seems to do the trick at a great price.

Rated 4 out of 5 by from No Assembly Instructions are Included After assembling this composter, it appears to be very sound. HOWEVER... there's no assembly guide included. I'm not a moron, but I'd like to have some direction on how to put this thing together. Instead of having instructions in front of you, you're directed to a guide online. The manufacturer is assuming that your laptop or desktop will be in the general vicinity of where you're assembling the item. THEN... when you actually access the guide, it's incomplete. It directs you to install four nuts and bolts per panel. WRONG. That's the four nuts and bolts ON THE SIDES. When you're assembling this, be sure to add the nuts and bolts that attach each panel to the other. It'll save you time, and you won't have to bring a second person into the process when reaching deep into the well with a wrench in one hand and screwdriver in the other.

It has fallen apart breaking at the point where the bar attaches to the stand. The plastic around the bar broke it could not handle the weight. I only put kitchen waste for a family of two, not a lot. The dual chamber style is a good idea but the manufacturer needs to reinforce the area around the bar that the unit turns on. I think 3 years is not a good record for little amount that I use it.

It's small, but the two bin, tumbler makes a good idea. My complaint is with really poor construction directions. The enclosed directions are worthless. Company directs you to a webpage. These directions are barely better. Illustrations and step by step are not inclusive enough or clear enough. The final statement [sic] "If you get to the last panel and it doesn't fit you installed incorrectly, take it apart and do it the other way." REALLY? How about better directions?!

Rated 4 out of 5 by from Great little unit Firit; its 's "SUPPOSED" to leak; thats how rain water gets out. Many people use this TEA for new plants. Next, if its slimy and wet you need more dry material. Basicly its 2 to 1 of green/kitchen scraps to dry material IE leaves, dried grass ect. You should layer, leaves, wet, garbage, wet, some garden soil to add micro organisms, then more dry grass/ or leaves. FINALY dampen. YOU SHOULD ONLY DAMPEN EACH LAYER. It heats up in a few days and you rotate "one turn", every few days add kitchen scraps and then a layer of dead stuff, in the summer sprinkle with some water, and rotate ONCE every couple of days. If it smells or gets slimy its too wet and you need more dry material. After about teo weeks move it to the finished side and use a little between layers of garbage and dry leaves/grass as a starter.

Rated 4 out of 5 by from Easy Assembly/ Nice look...productivity info to come later After months of debating and deliberating, and getting approval from my wife once she heard from someone else about composting, I finally purchased this Composter. It was easy to assemble after reviewing the instructions and following the video on YIMBY website. It's very light weight and easy to move, and I don't think that's due to me being 6'3" 315lbs. I've already placed it in my backyard and added material. Don't be ashamed if you need help as my arms are longer which made it easier for me to carry. The reviews certainly helped, and I added the compost starter, also available at HD to help out. It even has a nice look to it. Also I took the other reviewers advice and sprayed the legs and metals with Rust inhibitors. I choose Rust-o-leum. The door is a bit smaller, but it should be easy to manage.
