          Speedy Process: Twin Chamber Rotating Compost Bin 35 gallons

          Twin Chamber Rotating Compost Bin 35 gallons
          Twin Chamber Rotating Compost Bin 35 gallons
          Pros
          • Take around 14 days for a new usable soil-enriching compost pile – rotary construction & adjustable air vents
          • Provide a constant compost source to use all-year-round - twin-chamber design
          • Easy to load compost ingredients & protective against outdoor elements and animals - tightly locking slide-aside doors
          Cons
          • Wish the doors were smoother to open/close
          • Instructions are a bit unclear
          • Difficult to put together

          The Twin Chamber Rotating Compost Bin is able to not only hold the largest amount of compost (up to 37 gallons) but also speed up the composting progress.

          In fact, it only takes around 14 days to make a whole new soil-enriching compost pile that is usable – something that the traditional design needs at least 4 weeks.

          The twin-chamber design, on the other hand, allows you to make two separate compost batches at different decomposition levels. In other words, you’re completely on the proactive sides in creating a constant compost source to use all-year-round.

          For each chamber, there’s a tightly locking slide-aside door that keeps everything well protected against outdoor elements and animals. The openings are also wide enough to easily load your compost ingredients. Very convenient!

          Another notable feature about this product is its adjustable air vents, meaning that you can easily adjust them to the desired size based on specific composting stages.

          How To Choose The Best Small Outdoor Compost Bin?

          Types

          There are many types of compost bins to choose from, but below are some of the most suitable types for using outdoor.

          • Manual composters: they are small and affordable, but require manual composting, meaning you have to turn over the organic matter yourself.
          • Tumblers: this type is shaped like a canister and you just have to spin the barrel to turn the material inside.
          • Worm composters: these bins rely on compost worms to convert organic matter into fertilizer.

          Size

          The choice of size depends on the amount of compost you want to make, in balance with how much room you have to place the compost bin. Therefore, it’s best to calculate the amount and measure the space before choosing a composter.

          Ventilation

          It takes less time to make compost from organic matter when there is a lot of oxygen flowing in. You should look for a composter with many aeration holes, which reduces the amount of time required for the matter to compost.

          FAQs

          Are compost bins worth it?

          Sure, it’s worth it if you want to make your own nutrient-rich soil for your garden or flower beds. It’s also a great way to save money and take advantage of the discarded material at your home.

          What are the tiny flies in my compost bin?

          The tiny flies that you find in your compost bin are most likely Vinegar flies, which often appear near rotting fruits and compost. They are actually harmless and only feed on the fruit and vegetable waste only.

          Do you need 2 compost bins?

          While this is not a must, you should use at least 2 compost bins, one of which contains decomposing material and the other contains finished compost that you can use immediately.

          Should compost bins be in the sun or shade?

          Either way is fine. Putting the compost bin in the sun speeds up the composting process, but it also makes the pile dry out faster if you’re in a warm climate.

          Do compost bins attract rats?

          Yes, they do. Because rats will see compost bins as a source of food for them.
