Doesn’t smell at all when closed, and there's only minimal odor when the lid is off.

The Original Vermihut Plus 5-Tray Worm Composter is a solid choice for anyone looking to start vermicomposting, whether indoors or outdoors. One of its primary strengths is its size and design; with five trays and the option to add more, you can efficiently compost a substantial amount of food waste, making it great for families or avid gardeners. The dark green HDPE material is durable and sustainable, ensuring that it can withstand various weather conditions if used outdoors.

Ventilation is another highlight thanks to the innovative M-board feature, which enhances air flow for better composting efficiency. The V-board and air-vented lid help control odors and moisture, addressing common concerns for users. Additionally, the included accessories, such as the coconut coir and worm food magnet, are thoughtful additions that enhance the experience for beginners.

On the downside, the 12-pound weight might make it a bit cumbersome to move around, especially when full. Some users might find that a larger capacity would better suit their composting needs. While the product comes with technical support, not everyone may require this assistance, which can be seen as an unnecessary feature for those who are already experienced with worm bins. The Vermihut Plus is designed for users who are serious about composting. If you're looking for something more basic or smaller, this might feel a bit too advanced. This composter is a strong contender in the worm-bin category, particularly for environmentally conscious individuals looking to recycle food waste effectively.

An ideal size and quality for personal use, making it easy to manage and bring worms indoors during winter.

The Vermihut Plus Worm Composter is a versatile option for those new to vermicomposting, offering a sustainable design suitable for both indoor and outdoor use. The bin comes with five trays initially, and more can be added, providing flexibility in capacity for varying composting needs. Its HDPE material is both durable and light, weighing just over 12 pounds, making it relatively easy to move around as needed.

A standout feature is the M-board, which enhances airflow, promoting efficient composting while ensuring that the worms remain healthy. The V-board, combined with coconut fiber components, helps manage odors and moisture, making it more convenient for indoor use without worrying about unpleasant smells. The inclusion of 'shoes' prevents pests from entering, a thoughtful design detail that protects your compost. The all-in-one base and liquid tray simplify setup by reducing the number of parts that need assembling, making it easier for beginners to start composting right away.

However, at 33 inches in height, it might be cumbersome for those with limited space or who prefer a more compact system.

It is particularly beneficial for environmentally-conscious users who wish to engage in sustainable practices without the complexity of traditional composting methods.

Buying Guide for the Best Worm Bins

Choosing the right worm bin is essential for successful composting and ensuring that your worms thrive. Worm bins come in various sizes, materials, and designs, and selecting the right one depends on your specific needs and circumstances. Here are some key specifications to consider when choosing a worm bin, along with explanations to help you make an informed decision.
SizeThe size of the worm bin is crucial because it determines how much waste you can compost and how many worms you can keep. Small bins are suitable for individuals or small households with limited kitchen waste, while larger bins are better for families or those with more organic waste. To choose the right size, consider the amount of food scraps you generate weekly. A general rule of thumb is that one square foot of surface area can handle about one pound of food waste per week.
MaterialWorm bins can be made from various materials, including plastic, wood, and metal. Plastic bins are lightweight, durable, and easy to clean, making them a popular choice for beginners. Wooden bins are more breathable, which can help regulate moisture levels, but they may require more maintenance to prevent rot. Metal bins are less common and can be prone to rust. Choose a material that fits your maintenance preferences and the environment where the bin will be placed.
VentilationProper ventilation is essential for maintaining a healthy worm bin environment. Worms need oxygen to survive, and good airflow helps prevent odors and mold growth. Bins with built-in ventilation holes or systems are ideal, but you can also create your own by drilling holes in a plastic bin. Ensure that the bin has enough ventilation to keep the contents aerated without drying out the bedding.
DrainageDrainage is important to prevent excess moisture from accumulating in the worm bin, which can lead to anaerobic conditions and harm the worms. Look for bins with a drainage system or the ability to add one, such as a spigot or holes at the bottom. If you choose a bin without built-in drainage, you can manage moisture levels by adding absorbent bedding materials like shredded paper or cardboard.
DesignWorm bin designs vary, with some featuring stackable trays, continuous flow systems, or simple single-compartment setups. Stackable trays allow for easy harvesting of finished compost, as worms migrate upward to new trays. Continuous flow systems have a mesh bottom that allows castings to fall into a collection tray below. Single-compartment bins are straightforward but may require more effort to separate worms from compost. Choose a design that matches your composting goals and how much effort you're willing to put into maintenance.
LocationConsider where you will place your worm bin, as this can influence your choice. Indoor bins should be compact and discreet, with good odor control. Outdoor bins need to be durable and able to withstand weather conditions. If you plan to keep the bin in a garage or basement, ensure it can handle temperature fluctuations. Choose a bin that fits the space you have available and the conditions it will be exposed to.
