Introducing the Grodan Stone Wool A-OK Plugs 1.5"x1.5", renowned for their homogeneity and reliability. These plugs are the ideal foundation for automated processing, uniform germination, and a high success rate when pricking out.
Each plug boasts a uniform density, firmness, and fibrous structure. This uniformity extends to the distribution of water, nutrients, and pH-value throughout the plug, which significantly contributes to successful germination results.
Grodan plugs are not only homogeneous but also flexible and reliable. Their predominantly vertical fibrous structure gives the plugs excellent resilience. One practical advantage when pricking out is that the plug retains its shape, ensuring good contact with the block and promoting fast root growth.
An ideal balance between small and large pores in the stone wool of the plug ensures an optimum air-to-water ratio. This balance, coupled with the fibrous structure, facilitates an even distribution of feedwater throughout the plug.
In essence, the Grodan Stone Wool A-OK Plugs 1.5"x1.5" deliver homogeneity, flexibility, shape retention, and firmness that together provide the foundation for the optimal germination process and a uniform sowing result.
These A-OK Starter Plugs are perfect for starting seeds and rooting cuttings prior to plugging into larger Gro-Blocks. They come labeled with instructions in a shrink-wrapped sheet that fits a standard 10 x 20 tray (flat).
