Grodan A-OK Starter Plugs

Grodan A-OK Starter Plugs are stonewool propagation plugs engineered for seed germination and cutting propagation. Each plug measures 1.4in x 1.4in x 1.6in and arrives with a pre-cut planting hole, so seeds and cuttings can be set without additional preparation. The stonewool matrix holds a balanced ratio of air to water, giving young roots consistent moisture and oxygen through the establishment phase.

These plugs ship loose in the case rather than as connected sheets, which lets operators fill trays at whatever density a crop requires and pull individual plugs without tearing a sheet apart. The 1.5in square footprint drops into standard 10in x 20in propagation trays, and the tapered bottom guides roots downward for clean, uniform transplanting into Grodan Gro-Blocks or other stonewool substrates.
