The perfect way to root cuttings. Rockwool is a synthetic material that is sterile and absorbs moisture like a sponge, yet allows for good air flow to prevent disease. Simply place the rockwool plugs into a watertight tray and hydrate, then stick your prepared cuttings into the plugs, and cover with a dome to maintain high humidity while the cuttings root.

Includes 98 - 1.5" starter plugs.
