Grower’s Edge Block Covers

Grower’s Edge Block Covers block light from your growing media—which helps reduce algae.

Rockwool is a growing medium made of basalt melted back into lava and poured into a spinner in a process similar to making cotton candy. As a growing medium, rockwool has been in use for more than 40 years and is one of the most commonly used substrates in hydroponic productions across the world thanks to its inert properties, sterile start, and unique water-holding capacity.

Keeping the light off the rockwool will prevent algae growth on the rockwool. Any place in the system where nutrient solution exists, you need to exclude light as much as possible.
