How are worm casts made?

Our process is simple‭, ‬natural‭, ‬and economical‭.‬

Producing worm casts is cycle that we repeat every four weeks‭. ‬In a nutshell‭, ‬we just make sure that our worms are provided with‭ ‬a healthy environment to do what they do best‭.‬

Gro Worm

1. Mixing

We mix worms with organic substrate‭, ‬and place them into trays‭.‬

Gro Worm

2. Feeding

The worms are fed a nutrient-rich organic meal‭, ‬with water‭.‬

Gro Worm

3. Waiting

We wait four weeks for the worms to naturally produce worm casts‭.‬

Gro Worm

4. Separation

The worms are screened‭, ‬and separated from the worm casts‭.‬
