Living off the grid – whether by choice or by chance – is all about efficiency. You need to learn to make the most of your land, your water, and even your food waste. That’s where worm composting comes in. Worm composting makes use of mealworms and earthworms to create a valuable soil additive called vermicompost. This “worm tea” is made up of the worm’s waste as your compost exits the worms’ “tail”, called a “worm casting”. The worm tea that worm compositing generates is a very effective fertilizer, and is perfect for greenhouses and potted plants.

Before we get too far with this: don’t drink the worm tea.

That said, let’s go over a basic list of the materials you’ll need to make your own, DIY worm composting solution:

Worm Composting

Worm Composting | Step 1

spout added to compost bucket

Install the faucet/water valve into the bottom of one of the buckets. This is where the worm tea will come out, so you want it fairly low to make the job of extracting the tea easier.

Worm Composting | Step 2

holes being drilled into bucket

Remove the handles, then drill a number of holes into the bottom of the 3x buckets that do NOT have a water valve. Once the worm composting is actually happening, the tea will drop down from layer to layer through these holes, so they should be relatively small. Smaller holes are better for the tea, but take longer to make and are a bit more high maintenance, since they can clog.

Worm Composting | Step 3

measuring inside of bucket

Draw a line 8″ from the bottom of the 3 buckets you drilled into. That’s the fill line, and approximates the same 1:3 proportions of the “minimum cavities” left in pre-manufactured worm composting kits.
