RedRock Stonewool Starter Plugs

RedRock Stonewool Starter Plugs are a classic, trusted option for easily starting seeds and rooting clones. These lightweight and convenient plugs are great for growers looking for simple, reliable performance for early cultivation in both home grows and larger commercial setups. Crafted from high-quality stonewool fibers, they provide excellent water retention and aeration that creates the perfect environment for vigorous early root growth. With a fibrous structure, they evenly hold moisture while allowing excess water to drain — making them beneficial for healthy development and preventing root rot. Compatible with most hydroponic and soilless systems, they provide stable pH levels and promote healthy, stress-free transitions from propagation to veg growth. For growers interested in an expanded clay aggregate alternative, the RedRock Starter Block is a clean option that offers precise control.
