Know before you buy

Myco-tone is a blend of beneficial fungi that colonize the root system. This helps plants absorb more water and nutrients, which leads to stronger, more resilient root development.
No, this product is entirely organic and free from synthetic fertilizers or harsh chemicals. It relies on natural amendments like earthworm castings to provide nutrients to your plants.
While it is excellent for potting and transplanting, it is best used for established plants. For delicate seed starting, you may prefer a finer, lighter seed-starting mix to ensure optimal germination.
