Grodan A-OK Starter Plugs - 1.5 Inch (98 Plugs)

Grodan A-OK Starter Plugs - 1.5 Inch are stone wool starter plugs for starting seedlings and rooting stem cuttings, built for uniform propagation. This is clean propagation media that supports consistent early rooting and even starts across a batch.

These starter plugs are built around homogeneity and reliability, so each plug behaves predictably during the most sensitive stage of growth. The finely woven stone wool creates a perfect environment for young roots, helping roots develop evenly through the plug. With uniform germination as the goal, the material structure is designed to support uniform seedling results and stronger early plant consistency.

Each plug is made with uniform density, firmness and fibrous structure to help keep conditions consistent from plug to plug. That uniform density, firmness and fibrous structure supports even distribution of water, nutrients and pH-value through the plug, which can have a beneficial effect on germination results and initial crop development. When you want fewer weak starters and less variability, this level of consistency is the point.

Grodan A-OK Starter Plugs are also designed for smooth handling in real propagation workflows. The shape and firmness support automatic or manual processing, which makes large batches easier to manage with less disruption. A tapered bottom for improved transplanting helps the plug move forward cleanly into the next stage without losing its structure.

These starter plugs are suited to hydroponic systems where uniform starts and clean handling matter most. They’re a good fit for growers who want reliable propagation, strong early rooting, and more consistent seedlings or cuttings without changing their overall propagation approach.
