Mini-Blocks MM40/40 1.5" x 1.5" x 1.5" - strip of 15 - Improved - PRO / unwrapped
PRO simply means they do not come wrapped in the clear plastic outer wrap with a retail sticker and UPC code. The product itself is exactly the same, but costs less.
New Grodan Improved! Improved product at current pricing. New density + new hydrophilic technology = better water distribution and root development. The uniform distribution of water and nutrients throughout the block allows for more efficient use of the entire substrate volume Full saturation of the blocks with no dry spots and improved EC control with less water is achieved in the rootzone due to the uniform, optimized wool resulting in a sustainable water and nutrient use. Improved “re-wettability” able to more easily increase water concentration in the substrate.
NOTE: A full case of these cubes is 150 strips (2,250 Mini-Blocks). If you are looking to purchase full cases, simply order in increments of 150. When you add them to your cart you will see that the price has been changed to reflect the discounted case price.

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.
Grodan Rockwool Mini-Blocks are great choice for rooting cuttings. We recommend soaking them in pH 5.5 water before planting up with seeds or clones. Keep them under a dome to retain moisture and mist if necessary. From here, you can transplant into any growing medium, soil or hydro.
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.
