Cal-Mag™ Plus is a highly fortified calcium, magnesium and iron plant supplement formulated to correct common deficiencies. Supplementing your preferred nutrient program with Cal-Mag™ Plus is strongly recommended when using reverse osmosis water and when growing in coco coir-based medias to compensate for natural calcium draw. Cal-Mag™ Plus can also be applied as a foliar spray to further enhance growth.

Gro-Blocks are similar to a plant container. Need a 3 in pot? Then choose a 3 in Gro-Block. Small plants can be fully grown in our larger Gro-Blocks. Holes are perfect size for any 1.5 in starter plug. Come in packs labeled with instructions. Big Mama is Grodan's largest block ever produced! Big enough to grow a large plant for its entire life. More than twice the amount of wool as our Hugo Block.

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.

A-OK Starter Plugs for starting seeds and rooting of cuttings prior to plugging into the larger Gro-Blocks. A-OK Starter Plugs come labeled with instructions in a shrink-wrapped sheet that fits a standard 10 x 20 tray (flat). Note: Item #713020 is supplied without shrink wrap.
