Subpod is an in-ground worm farm, the first ever of its kind! Above ground compost systems are often difficult to maintain and attract pests. Worm farms that are above ground also fail when they get too hot or cold – but not Subpod. Subpod sits 90% below the soil level in your garden, so the compost worms that live inside can come and go freely (nourishing the soil directly). The soil insulates your compost and protects your worms from harsh weather, so you can keep composting no matter the season!

We designed Subpod to deal with all the common issues associated with traditional compost systems:

- It’s aerobic, using odourless microbes to speed up the composting process

- The ventilation panels keep it smell-free with fresh air

- It’s pest-proof and lockable (great if you deal with raccoons)

- It doubles as a garden seat, subtly hidden amongst your plants

Yes! Being underground is what makes Subpod different from other compost systems. The soil provides insulation and a way for worms and microbes to explore your garden and feed your plants.

Above ground compost systems struggle to keep worms and microbes comfortable, and even alive, in summer and winter – but underground they're safe and happy (which is the secret to good compost).

You can compost a much bigger variety of materials in Subpod than in other worm farm systems! See the full list below:

FOOD WASTE
Most food waste can be composted in Subpod without worry. Fruit and vegetable scraps, eggshells (crush them first), coffee grounds, used tea leaves, spoiled plant-based milks, grains, pastas, breads, nuts (and their shells), seeds, pits, husks and so on. Small amounts of meat, seafood, dairy foods, citrus, onion and garlic may also be added. Subpod can also process spicy herbs, peppers and oils but it’s best to introduce these slowly in small amounts at first, and only once your worms are fully established (after around three months).

PAPER & CARD
Most scrap paper and cardboard can be added to Subpod, as long as it’s not laminated or super glossy. Again, the smaller the pieces, the better. Junk mail, office paper, bills, envelopes (no plastic windows), post-it notes. Paper plates, tissues, egg cartons, paper cupcake liners, baking paper, even card and paper packaging is fine.

NATURAL FIBRES
Cotton wool balls and pads, tampons, toilet paper cores and even natural latex condoms and gloves can go into Subpod. Old clothing, face washers, napkins, tablecloths and very old towels can be used as long as they are made from natural fibres like cotton, tencel, linen, hemp or wool (no polyester, nylon, acrylic or blends) – just shred them into small pieces first. Washer and dryer lint is okay too, as long as it comes only from clothing made from natural fibres.

WOOD AND BAMBOO
Sawdust (no paint) is great. Toothpicks, disposable wood, bamboo and bioplastic cutlery and crockery can be composted, along with dead matches, bamboo skewers, garden prunings (cut 'em up small), and charcoal from the fireplace – as long as you wash off the ash which is too alkaline for Subpod.

HUMAN AND ANIMAL WASTE
Human hair and nail trimmings, used facial tissue, used cotton bandages and sanitary items can all be composted in Subpod, as long as they are made from 100% natural fibres. Pet hair of all kinds is fine, along with soiled newspaper and hay cage liners and faeces from vegetarian pets and livestock (rabbits, guinea pigs, hamsters, cows and horses). Dog and cat faeces are NOT suitable for Subpod if you’re eating the plants growing around it. But fine if you want to have a separate one for this purpose.

NOT COMPOSTABLE
You cannot compost non-organics such as plastic, tin cans, cigarettes, building waste, toxic waste, glass, or any other similar materials in Subpod.

One fully functioning Subpod can compost 15kg (30lbs) of food waste a week! The average family generates roughly 7.2kg of food waste a week, so Subpod can handle about double the waste your family should need it to.

It can take 1 - 3 months for the worm population inside your Subpod to build enough for it to compost at peak levels. It’s also possible to optimise your Subpod to compost even more waste by incorporating biochar into your system – but that's a little advanced.

We recommend Subpod sizes depending on how many people are in your household:

1-3 people = 1 x Subpod Mini

4-8 people = 1 x Subpod Classic

8+ people = 2 x Subpod Classic

Yes! Subpod is a vermi-composting system, which means it relies on compost worms to break down your food waste. Without compost worms, Subpod can't do its job.

We recommend buying worms for your Subpod locally if possible, but you can also find them online. If you need more information on how to buy worms, Read this blog!

Unfortunately, no. But we do have a few tips though!

• Try to purchase worms locally. Worms always seem to be happier if they don’t have to be shipped for miles across the country.
• Get a diversity of worms. There are 3 main types: Red Wigglers, Night Crawlers and Tigers. Each is better suited to different environments and temperatures, so it’s helpful to get all three.
• Jump on to our growhub community and see if there’s a local Subpodder that will give you some worms. Make a friend and score some worms at the same time!

• When you add your food scraps and carbon material to the Subpod, you'll need to mix them through using an aerator. This takes a few minutes each time you feed the worms.
• If the soil surrounding Subpod settles and starts to reveal the Subpod wormholes (beneath the airflow panels), more soil (and mulch) needs to be added to cover the holes.
• Otherwise, just keep feeding your worms and keep the blanket moist when you are adding more food.

Yes! Subpod can be installed directly into the ground. Subpods work the same planted directly in the ground as they do in a raised bed, however we find that raised beds are just that much easier to access and use Subpod.
