*** there are 98 pieces in a shrink wrapped package called a “flat” (fits perfect in the 10×20 trays)
A-Ok Starter Plugs™ are for starting seeds and rooting cuttings prior to plugging into larger Gro-Blocks™ or potted soil.
The 1.5” size fits perfectly in the Gro-Smart tray as well as all Grodan pre-drilled Gro-Blocks. One advantage of using the Gro-Smart tray is that it elevates the plugs above the waterline and ensures good airflow around the plugs. A-Ok plugs come labeled with instructions in a shrink-wrapped package that fits a standard 10 x 20 tray (flat).
Enjoy complete control over plant growth and nutrient systems with our Grodan Starter Plugs. Made from molten rock spun into cotton candy-like fibers and then compressed into blocks. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in sheets of 98 plugs. Seedlings started in plugs are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.
