Super Coarse Perlite
Perlite is a lightweight and porous volcanic glass that is expanded by heating .In gardening and horticulture, perlite is valued for its ability to improve soil drainage and aeration. This is making it an excellent choice for plant growth.
Perlite advantages
- Its sterile nature makes it highly suitable for starting seeds. There is little risk of root rot or damping off.
- Naturally contains minerals needed for plant growth.
- A non-toxic substance that doesn’t require rinsing like some other growing media does prior to use.
- Neutral pH doesn’t need to be adjusted, nor will it adjust the overall pH when mixed with other components.
- It can be used alone or mixed with other media to create potting mixes.
- Great for seedling germination or plant propagation as the particles allow for plants to be pulled from the perlite without damage to the root systems when it’s time for transplanting.
- Reusable year after year since it doesn’t decompose.
