Perlite as a Hydroponic Grow Medium

Definition: Perlite is a lightweight, porous material that is commonly used as a hydroponic grow medium. It is made from volcanic glass that has been heated to a high temperature, causing it to expand and form small, white, lightweight particles.

Benefits of Using Perlite in Hydroponics

Improved Drainage: Perlite has excellent drainage properties, allowing excess water to drain away quickly. This prevents waterlogged roots and helps maintain optimal oxygen levels in the root zone.

Aeration: The porous nature of perlite provides ample oxygen to the roots, promoting healthy root development and preventing root rot.

Lightweight: Perlite is lightweight, making it easy to handle and transport. It also reduces the overall weight of the hydroponic system, especially when compared to other grow media like rockwool or clay pebbles.
