Grodan 2″ Rockwool Mini-Blocks (24-pack)

How the Grodan 2″ Rockwool Mini-Blocks (24-pack) Works:

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 requirements of the plant through 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.

Grodan Delta blocks are the most uniform blocks available on the market. They feature improved grooves at the base to promote better drainage. They are available in a large assortment of sizes and configurations to suit all types of plants. These growing blocks are used for direct sowing or “blocking on” of Macro and Multiblock raised plants. AO 36/40 plugs fit well into the hole sizes provided by the blocks. The blocks can then be placed on top of a slab to provide for a larger growing volume.

Product details:

• Mini-Blocks sit in a tray (flat) without support for easy starting of seeds and cuttings.
• These Mini-Blocks are individually wrapped in white plastic to minimize algae growth.
• Remove wrapping and transplant into any loose media such as Grow-Cubes or coconut fiber or leave wrapping on and set on top of a larger Gro-block.
• Packed in easy tear-away strips, labeled with instructions.
• 2″ x  2″ x  2″ cubes

Product Tips:

Using a garden hose, completely saturate the blocks
with water. After soaking in the water you can begin planting as normal and watch your plants thrive. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.
