The Vivosun 11 lb Compressed Coco Coir Block does the same job in one step. A single 11.8\" × 11.8\" × 5.9\" block expands into 18 gallons of loose, ready-to-mix growing medium, about eight times the output of a standard 1.4 lb brick.\u003c\/p\u003e\n\u003cp\u003eThe Vivosun 11 lb block is made from natural coconut husk fiber and rinsed multiple times with fresh water for balanced pH and low EC, which helps prevent salt buildup in the root zone. Its porous fiber structure drains freely and keeps roots oxygenated while holding water and nutrients within reach. That makes it a reliable base for bulk potting mixes, as well as an amendment that loosens heavy clay soil and improves drainage across garden beds.\u003c\/p\u003e\n\u003cp\u003eExpanding the block takes 9–11 gallons of water and a container large enough for the full 18 gallons. Once expanded, mix in organic fertilizer and buffer with a cal-mag solution before planting. Compressed, it stores in a fraction of the space of bagged media, so you can keep it on hand until the next bed refresh, transplant, or grow cycle.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin: 20px 0;\"\u003e\n  \u003cvideo src=\"https:\/\/cdn.shopify.com\/videos\/c\/o\/v\/5698a37317184ab188cb61d7fd5e2b20.mp4\" style=\"width: 100%;
