Buying Guide for Compost Bin for Garden and Outdoor
Type of Composters
One of the most important decisions to make while selecting a compost bin is the type of composter you need. Generally, there are three types of composters available in the market. A brief detail of each type is given below.
Batch Composters
Batch composters are suitable for gardeners who want to do composting in a single phase rather than an ongoing process. In batch composters, all the materials are added in a fixed ratio, and then the composting process starts. Batch composters need regular attention. You need to turn it in daily, mix the contents with a pitchfork, and check moisture levels. Batch composters help in creating compost faster as compared to other types. A good batch composter bin will typically 2-3 months to make the compost ready. While one batch is going on, you can use compost bins or make open piles to collect your organic waste.
Continuous Composters
If you want to compost regularly, a continuous composter is one you need. In this composter, you keep on adding waste from above, and the ready compost settles down to the bottom of the bin, which can be removed with the help of openings at the bottom of the bin. They are sealed with a lid, which helps in keeping the rodents and insects away from the waste. It also keeps the smell sealed in the bin.
Worm Bins
Worm bins use worms for composting purposes. Some people also use worm bins as indoor composting bins. The worms help in smell elimination as they consume the bacteria before they can smell. Worm bins come in different capacities to house worms, and the speed of composting depends on the number of worms a bin can accommodate.
Design
The design of the bin matters a lot. You must select a bin that has an effective air inflow, a proper lid that seals the entry of rodents and insects, stops smell from escaping, and keeps rainwater away from the bin because excessive moisture can destroy and slow down the composting process. If you are selecting a tumbler, you should check the rotating mechanism. The lid of the bin should be large enough for you to throw in the waste and shuffle it around once in a while.
Size
When you talk about the size of the composter, a couple of things play a part in it: the size of your lawn and the volume of waste you generate. If the size of your lawn is small and you have a small waste generation, you can select a small bin. On the contrary, if you have a big lawn and other plants around your house, you will need a larger bin. If you produce huge quantities of organic waste, you will still need a larger bin for composting.
Material
Material directly impacts the durability of your bin. Plastic bins are cheap as compared to metal bins but are not durable as compared to metal ones. Plastic bins can also retain some odors. Metal bins are heavier in weight.

Tips for Better Results
Some people find their composting bins too wet or smelly. That may be due to various reasons. Follow the tips below for better results.
Ratio
