Home Vermicomposting Kit

The kit includes the Pro Worm Composter (choose between the 32 L 2-tier model or 48 L 3-tier model, with the option to add an extra 16 L tier), live red Californian worms (100 or 200 units, depending on the option you choose), coconut fiber to prepare the initial bedding, and a beginner's guide to home vermicomposting created by Urban Green Club.

The 100 worms are enough to start in homes that generate few vegetable scraps or to take it slower at the beginning; if you cook daily with lots of vegetables and fruit or want the system to scale up sooner, we recommend the 200-worm option, which will be able to process more waste from the first few weeks.

When used correctly, it does not smell bad: the odor is similar to damp forest soil, because the decomposition carried out by the worms is rapid and occurs in the presence of oxygen. Bad odors and flies usually appear only if it is overfed, there is excess moisture, or non-recommended food is added; this is corrected by reducing the food, adding dry material (cardboard, unprinted paper), and aerating slightly.

Yes, it is designed to also be used indoors as long as it does not receive direct sunlight or rain: the kitchen, laundry room, or a well-ventilated corner are common locations. You can also place it on a sheltered terrace or patio; the key is to keep it in the shade, at a stable temperature, and away from sudden changes.

You can add kitchen vegetable scraps (raw fruits and vegetables, coffee grounds, loose tea leaves, crushed eggshells, small amounts of brown paper and cardboard), always in small pieces and alternating with dry material.

It is advisable to avoid or strictly limit: citrus, onion, garlic, cooked foods, salted or oily foods, bread, and flour.

You must not add: meat, fish, bones, dairy, pet waste, very fatty or saucy scraps, non-organic materials (plastics, aluminum, synthetic fabrics, coal ash, chemically treated waste).

The Pro Worm Composter is designed for low maintenance: simply add vegetable scraps once or twice a week (or whenever you have a small bucket full) and always cover with dry material to balance the moisture. The actual time spent caring for it is usually just a few minutes per week: emptying your scrap bucket, chopping up larger pieces, covering, and closing.

If you are going to be away, simply leave the worm bin with enough moist and dry material; the worms can go several weeks without receiving new scraps as long as the bedding remains moist and aerated. Upon your return, gradually resume adding waste so they can return to their normal pace.

Solid humus does not appear overnight: starting from a small core of worms, the scraps are transformed into humus over several months, depending on the temperature and the amount of worms and waste you generate. The important thing is to see the material darken, become finer, and smell like forest soil: that is the moment to harvest and use it.

In contrast, liquid humus or leachate (the liquid collected in the bottom tray) usually begins to appear much sooner, in the first few weeks of use, when there is already sufficient moisture and decomposition underway. The general recommendation is not to use large quantities of "fresh" leachate directly on edible plants, but rather to recirculate it back into the worm bin itself or, if you use it as fertilizer, always dilute it (approx. 1 part leachate to 10–20 parts water) and apply it to the soil; never use it if it smells bad or is clearly fermented.

You can choose between the 2-tier model (32 L) and the 3-tier model (48 L), and add an extra 16 L tier if you need more capacity over time. These volumes are designed for urban households that generate vegetable waste for 1 to 4 people; if you cook a lot with fruits and vegetables, the 3-tier model offers more room.

The Pro Worm Composter and the rest of the kit's components are covered by Urban Green Club's exchange and return policy: if something does not arrive in good condition or there is a problem with the product, you can manage the issue from the “Refund policy” section of the website. There you will find the updated terms and the steps to request an exchange or return.

Yes. The solid worm castings that you get from the Pro Worm Composter are an organic fertilizer that you can mix with the substrate in your pots or raised beds (between 10 and 20% of the total mix volume) or use as a top layer around your plants to improve structure, water retention, and nutrient availability.

The liquid humus or leachate can also be used, but always with certain precautions: use it diluted (for example, 10% leachate in irrigation water) and apply this mixture every 2–3 weeks to the soil of your pots or garden, avoiding wetting the leaves of leafy crops directly if you have any doubts. Never use leachate that has a bad odor or strange appearance; in that case, it is better to discard it or recirculate it through the vermicomposter so it can continue to mature.
