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]

Tumbling Composter with Two Chambers for Efficient Batch Composting is rated 4.3 out of 5 by 356.
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.

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 5 out of 5 by from Did my research before buying, GREAT! I did my research before buying this, and I hope you're doing the same. Don't just buy things on a whim expecting it to be guaranteed to satisfy!! Do your homework, so that you know in the end your finished product will be great! I put this thing together all by myself in one hour with a beading pair of pliers, and a cheap (practically twisted) flat head screw driver. The instructions are worthless, so don't even pay attention to it, just use it as a guide for the contents. Check out this video on YouTube which helped a lot. Lay out all your screws/nuts & pieces, and bundle the ones that are the same. Make sure when you're building the actual barrel that you are making sure all the pieces lock into each other. The panel with the sliding door has a different piece that fits into a specific side. Find that first before you start. If you will be using the partition to create two chambers, be sure to put that in BEFORE you finish adding the last three panels. I hand tightened everything while building, then went back and tool tightened them to secure(in case I made a mistake and had to take anything apart). I also took into consideration the rusting of the screws since I live in Hawaii(being surrounded by salt water makes EVERYTHING rust), so I used a spar urethane by Helmsman/Minwax I had on hand to paint each screw front & BACK. Now onto the actual composting. You need to AGAIN do your homework on composting. Don't think that all you're going to do is throw your waste in there and it'll pop out like magic! There's a specific ratio of carbon(straw, dried leaves, paper, etc) to nitrogen(hay, kitchen scraps, weeds/grass, greens), airflow, and water in order for decomposition to work. If your ratio is off, you'll get a sludgy, stinky mess! It should never stink, but smell almost sweet like wet alfalfa. Your compost should also be creating its own heat as well, so on cold days there should be warmth coming from your tumbler. If there's no self heat, your ratios are off!! You may want to buy Compost Starter from Home Depot to give your compost a jump start on the decomposition process....or a handful of already composted material is just as efficient. Also, try your hardest NOT to fill the tumbler to the top, 3/4 is great. You need heavy tumbling to help break everything down. If you're looking for quantity, buy another tumbler, or a different brand that will hold more. DO NOT ADD WORMS OR BENEFICIAL BUGS! They will die in the decomposition process with all that heat and constant tumbling! Add those later, outside of the bin. The convenience of this tumbler is to fill one side, then start the opposite side. Once you fill one side CORRECTLY, do not add more things to it, otherwise it'll take longer. Also make sure you crumble everything as small as possible! The tumbler was meant for fast composting, but that can't be achieved unless you help it out with the breakdown process. Crush your leaves, finely chop all your kitchen scraps, break your branches as small as possible, soak your cardboard/paper to soften it, etc. If using manure, be sure to dry it out well before adding to your compost. Manure needs to be aged thoroughly before adding to plants, otherwise it'll burn their roots. Dry it out for a month before adding to your compost pile, and be sure to add appropriate carbon ratios to balance it out. Manure is high in nitrogen, so a good balance is 3 parts carbon to every part manure. Once your compost is thoroughly decomposed and ready for use, you can leave it in and scoop out what you need. If you want to lay it all in your garden bed, follow these instructions: Allow your compost to dry out completely by opening all vent holes and leaving the sliding door open on that side. Wet compost will stick to the sides and not fall out easily. Place a tray or tarp under the tumbler and vigorously shake it to loosen anything from the insides. Spin your tumbler so the door faces the tray/tarp underneath, and now using the door as a "lock," slide it open through the legs to hold the tumbler in place. Now just bang the sides and all your compost will come flowing out.

Rated 1 out of 5 by from NOT Durable, Impractical Design Yes, it's a pain to assemble but the finished product is ideal for small urban households who don't produce a lot of waste and are looking to keep it off the ground and away from urban critters. These are the reasons I purchased this composter but the cheap materials and poor design have made me regret the purchase completely. Reasons to avoid this product: 1. The plastic around the center turning point ripped under the weight in the bin, despite the fact that I tried to keep both chambers equally full. This resulted in leaking compost goop and an uneven spin. The rip also caused the chamber to only be able to sit in a way that caused the rip to worsen over time. By the second summer, this thing was completely broken and useless. 2. The chambers are stupidly difficult to empty: you cannot turn the chamber to have the opening completely upside down because then you cannot reach in and scoop anything out. Also, there are so many plastic flanges in the actual chamber that it's hard to scoop without hitting them, making emptying this thing only possible by one small scoop at a time. 3. The plastic expanded/contracted in weather changes, making sliding the door either way difficult, usually resulting in pulling too hard and taking the entire door off then fighting to get it back into place in its slots. If you live anywhere with varying temperatures and/or wet weather, avoid this thing - it cannot handle the weight of the compost without breaking, let alone stand up to various seasons. It's cheap garbage that doesn't last!

Rated 5 out of 5 by from Best Composte Bin Ever I've had many compost bins, i.e. wire fencing, homemade with plastic garbage cans, tall rectangular with bottom slots for getting the "Black Gold" out. By far this tumbler is the BEST. Easy to put together, works very fast, heats up nicely. My first was two years ago. This year getting rid of the rectangular one and purchasing a second tumbler.

Rated 1 out of 5 by from Worst composter I agree with several of the other reviewers. I have had this composter for two years now. It took hours to put together and needed additional parts, etc., to actually make it fit and work. When filled, it leaks and creates slimy sludge that requires a lot of dry material to absorb. It also smells like a sewer most of the time. Once cured, you end up with big balls of dirt clods. That's after you wrestle the material out of the bin by hand, which is hard to do because of all the bumps and things inside the bin. The price was good and that was the only thing that it has going for it. Wish I had not purchased it.

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.
