About This

• FROM 1 BRICK, GET 5-6 POUNDS: Just add water — this compressed coir brick expands into fluffy potting mix for seed starting, vegetables, herbs, containers, raised beds, and mushroom substrate. Stores compact, plants huge.
• PROFESSIONAL-GRADE, NOT GENERIC: Triple-washed to flush plant-killing sodium, then calcium-buffered to prevent Ca/Mg lockout. Most expanding coir bricks skip these steps — Myco Coco gives you the cleanest expanding substrate on the shelf.
• RHP CERTIFIED — THE GOLD STANDARD: RHP is the Netherlands certification verifying coir is free of pathogens, weed seeds, and excess salts at every stage. Under 5% of retail coir carries it. Your seedlings and mushrooms deserve it.
• PEAT-FREE, 100% RENEWABLE: Coir is a byproduct of coconut harvest — no peat bogs disturbed, fully biodegradable. Balanced pH (5.8–6.5), low EC, and OMRI-eligible inputs make it as gentle on your garden as it is on the planet.
• MYCOLOGIST-MADE: North Spore grows USDA-certified organic mushroom growing supplies in Portland, ME. The strictest substrate standard in horticulture now grows your tomatoes, herbs, and houseplants — backed by our Grow With Confidence guarantee.
