Collection: Rockwool

Rockwool is a substrate many growers use in hydroponic operations, but it can be used to start seeds and clones as well!

Due its physical structure, rockwool drains excess water quickly! Yet, it retains small amounts of water near the bottom of the cube! This unique property allows plants to attain adequate hydration while allowing more air to circulate and oxygenate the roots!

Rockwool doesn’t break down or erode over time and can be reused many times.! Boiling or steaming between uses is recommended to kill pathogens!
