Reusing LECA

One of the many advantages of LECA, though it takes energy to mass produce and sell, is that it's a reusable medium. If your LECA's previous inhabitant was a healthy, disease- and pest-free plant, it needs nothing more than a good rinse to properly prepare it for re-use.

If the LECA is moldy, or had a root-rotted or pest-infested plant potted in it, there are some additional steps you might want to take before re-using the medium. Different methods of sterilizing LECA include:

- Sun Sterilization

- Hydrogren Peroxide

- Bleach

- Boiling

- and my current favorite for small amounts, the microwave. Click here to see how.
