Question 1

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 2

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 3

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 4

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 5

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. To do this, feed only one compost bay until all the worms migrate to that side. You can then scoop out your finished compost from the other bay after two weeks, and begin the process again. Unlike other compost systems, you don’t need a resting period to collect your compost. By alternating bays, you can keep feeding your system as you collect your compost.

Question 6

How to look after my Subpod in extreme heat?

Accepted Answer

The Subpod lid is insulated to keep out direct heat from the sun, but if you live in an extremely hot climate, we recommend installing your Subpod in a shady location to prevent overheating or build a shade structure to protect it in the heat of the day. Keeping the worm blanket wet/moist will also help to keep your Subpod cool.

Question 7

Why does my Subpod smell?

Accepted Answer

If your Subpod smells, it indicates that food is rotting before the worms can eat it or there is not enough oxygen in the system.

In most cases, adding more carbon should balance your Subpod out

Add carbon sources such as shredded newspaper or cardboard, coconut peat, wood shavings, dry leaves or sawdust each time you feed your Subpod, along with a handful of biochar.

Have you been using your aerator? Each time you add your food waste make sure you use the compost aerator to mix the scaps thoroughly whilst also adding oxygen to the Subpod, which creates a healthy, fresh-smelling aerobic environment.

Question 8

What can you not put in a worm compost bin?

Accepted Answer

Do not put intensely spicy foods into your worm composter, such as ginger or an excessive amount of citruses, as well as milk products, meat products, bones, oils, lard and other fats.

Question 9

How long does it take worms to compost?

Accepted Answer

Creating quality composts takes approximately 2-3 months. It mainly depends on the number of earthworms and the quality of 'food'. Creating quality composts takes approximately 2-3 months. It mainly depends on the number of earthworms and the quality of 'food'.

Question 10

What do I do about waste shrinkage in the lower trays of the wormery?

Accepted Answer

It is important to maintain the level of waste in the lower trays of the wormery as the waste is reducing. If the level drops too much then it makes if difficult for the worms to access the levels above.
