Product Information

Perlite, an expanded form of amorphous volcanic glass derived from naturally occurring siliceous rock and processed at high temperatures to yield a lightweight, porous aggregate, offers unparalleled advantages as a growing medium in hydroponics where it revolutionises soilless cultivation for both commercial and home growers.

Its key properties include sterility and freedom from pathogens, a pH-neutral profile (typically 6.5 to 7.5), exceptional absorbency that retains up to four times its weight in water while ensuring superior drainage and aeration for optimal root zone oxygenation, and a unique capillary action that draws nutrient-enriched water from reservoirs precisely at the rate required by plants, thereby eliminating risks of overwatering or underwatering that could lead to root rot, nutrient imbalances, or stunted growth. This precision fosters accelerated plant development, enhanced root expansion and robust disease resistance.

Perlite's versatility shines when blended with coco coir or living soil, where it enhances drainage, prevents compaction, and promotes healthy microbial activity for even more resilient and productive organic growing environments.
