Grodan® A-OK Starter Plugs™, 2" Square Shaped Plugs, Shrink Wrapped (50 Plugs/Sheet)

A-OK Starter Plugs, 50 Plugs Per Sheet, Shrink Wrapped

A-Ok Starter Plugs™ are for starting seeds and rooting cuttings prior to plugging into larger stonewool Gro-Blocks (growing blocks).

Highlights

• Grodan plugs are designed for fast, uniform propagation of cannabis cuttings and seedlings, resulting in maximum plant quality and easy handling.
• Grodan A-OK plugs are designed for seed and cutting propagation prior to “blocking on” into larger growing blocks.
• The V-shape design of the plug discourages tangling of roots between the plugs in the A-OK plug sheet.
• A’OK plugs come in a sheet that fits a standard 10×20 flat.
• Square-shaped plugs are connected at the top to form a sheet that fits a 10/20 tray. Plugs with a tapered bottom are ideal for transplanting cannabis crops in hydroponic systems.

What is Stonewool?

Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. 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 graduated sizes. Seedlings started in cubes 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.
