How much worm castings should I include in a substrate mix?
We typically recommend making worm castings around 10% of an overall substrate mix to provide a healthy dose of nutrients whilst maintaining a balanced profile.
How to use worm castings?
The easiest way to use worm castings is to simply mix them directly into your substrate before adding to your terrarium. Alternatively, they can be sprinkled on top of the substrate/soil and any watering action will pull through the nutrients.
Do worm castings smell?
Nope! These castings smell completely inoffensive
Are worm castings a suitable substrate on their own?
No, pure worm castings are not a suitable substrate medium on their own. They’re prone to compaction and lack the drainage and aeration qualities of a balanced mix.
