Grodan A-OK Starter Plugs, 36/40, (1.5 inch x 1.5 inch cubes) sheets of 98 Unwrapped in Bulk FREE SHIPPING
SPECIAL PALLET PRICING (30 sheets in a case with 12 cases on a pallet in Bulk) Grodan A-OK Starter Plugs, 36/40, (1.5 inch x 1.5 inch cubes) sheets of 98 Unwrapped in bulk are engineered specifically for commercial propagation. This premium rockwool grow media is the ideal choice for professional cultivators looking to go wholesale. Each 1.5-inch starter plug is manufactured from molten basalt rock spun into sterile, inert fibers, ensuring a clean, pathogen-free environment for starting seeds and rooting cuttings. The 36/40 size designation provides a larger volume of substrate than smaller plugs, offering an optimal balance of water retention and aeration to encourage rapid root initiation. These sheets of 98 plugs fit seamlessly into a standard 10 x 20 propagation tray (flat). The "unwrapped" design means there are no individual plastic or paper wrappers around each cube, which significantly improves air circulation, prevents localized moisture stagnation, and allows roots to grow freely. This design also ensures that individual plugs can be easily separated by hand from the sheet without requiring any cutting tools. To prevent the plugs from becoming waterlogged, the stone wool structure is designed to retain a consistent 30% air porosity; simply place them in a well-draining tray and avoid standing water. Each plug comes with a pre-formed dibble hole to perfectly position seeds or cuttings. Because raw rockwool has a naturally high pH, it is essential to soak these plugs in a pH-adjusted nutrient solution (ideally 5.5 to 6.0) prior to planting to ensure optimal nutrient uptake. Once your seedlings or clones are established, these versatile plugs can be transplanted directly into soil, coco coir, or larger Grodan Gro-Blocks without transplant shock.
