Kickstart your garden with Mycelium’s Seed Starter Coco Coir Brick, a premium OMRI-certified organic growing medium designed specifically for seed germination and root development. Unlike traditional potting mixes, our finely textured coco coir ensures optimal aeration, moisture retention, and drainage, creating the perfect foundation for healthy, vigorous seedlings. Expanding 8-10 times its original size with just 8-10 gallons of water, this 10 lb brick transforms into a fluffy, well-balanced medium that supports strong root growth and disease resistance. It provides a clean, chemical-free environment for young plants to flourish. Ideal for vegetables, herbs, flowers, and microgreens, Mycelium’s coco coir seed starter can be used alone or blended with compost, perlite, or worm castings for a customized planting mix. Whether you're growing in seed trays, starter pots, or hydroponic systems, this sustainable, renewable alternative to peat moss ensures optimal seedling success from day one.
