Question 1

What to do with worms that have gone down into the sump/ bottom section?

Accepted Answer

Sometimes some of your worms migrate to the sump which is mostly more distressing for you than them to be honest. They do explore their surroundings and they are usually fine in there as long as the liquid is draining reasonably regularly. The reason they go down to the sump on occasion isn’t really known – in winter it’s possible they are heading down there to keep warm as in their natural environment they do burrow deeper to below where the ground is frozen. Either way generally this isn’t a concern. If it is a real problem add some crumpled up newspaper and leave the tap open.

Question 2

My worms are eating the moisture mat, is this okay?

Accepted Answer

Your moisture mat is just there to encourage your worms to work in the surface of the waste and as it is biodegradable the worms will eventually eat it. If the moisture mat is disintegrating quickly you can add more waste.

Question 3

How does Subpod differ from other worm composting systems?

Accepted Answer

It allows you to compost directly in your garden allowing the worms and microbes to distribute nutrients into the soil.

Because you’re composting in the soil, your system is insulated → which means you can compost in a variety of climates

Subpod sits 90% below ground, which deters pests and predators

The worms are able to move freely between the Subpod module and the surrounding garden which creates a worm friendly environment.

The Subpod has a unique modular design, which allows multiple systems to be installed in one bed and cater to larger volumes of waste.

Question 4

How much food waste can be processed in Subpod?

Accepted Answer

Once your worm population builds up you can feed your Subpod 30L (7.9 gal.) or 15kgs (34 lb) of food waste per week.

Question 5

What are the dimensions/specifications and capacity of the Subpod?

Accepted Answer

The external dimensions are: 750mm (29.5 in.) L x 450mm (17.7 in.) W x 430mm (16.9 in.) H, including the lid. The internal dimensions are: 710mm (28 in.) L x 410mm (16.1in.) W x 290mm (11.5 in.) H below the soil level.

A total internal volume of 115L, (30 gallons), which gives a total composting volume of 84L (22 gallons) due to the soil level and air flow area at the top.

Question 6

Does Subpod need any maintenance?

Accepted Answer

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.

Question 7

How many worms do I need per Subpod?

Accepted Answer

You'll need a minimum of 1000 worms, but 2000 is better. If you really want to kick start your Subpod, you can add up to 4000 worms.

Question 8

What material do you recommend for the worm bedding in the Subpod?

Accepted Answer

The ideal material for worm bedding is coconut coir. It holds water very well, which keeps the worms moist, can be a food supply for your worms and is also a good carbon source. Dried bricks are easily purchased in the gardening section of garden stores such as Bunnings and Home Depot.

If fine and coarse forms are available, choose the fine.

Follow the directions on the pack to pre-soak the coir with water until it has fully swelled and is uniformly damp, but not dripping wet. The worms can be directly added on top of this pre-moistened bedding.

To save money, shredded (non-glossy) paper or newspaper is another option, but not as ideal for initially setting up bedding as it clumps together when wet. Any carbon material can be used as long as it is damp.

Question 9

Does my food waste need to be broken up into small pieces before adding to the Subpod?

Accepted Answer

You don’t need to chop everything up small for the worms, but it does speed up the process so your food will break down even faster.

Composting will still take place in the warm, moist environment if you put in larger chunks. The worms will just wait until the microbes have softened up the more resistant pieces.

Remember to use the aerator when you add food so larger chunks are sent below the surface to break down, rather than drying out.

Question 10

How and when to harvest the compost/castings?

Accepted Answer

After 2-3 months or when your Subpod is full, you can harvest your Subpod compost.
