The Harvest Company Coco Coir

Buffering with calcium nitrate replaces the naturally occurring sodium in raw coconut coir with calcium. This process stabilizes the medium's chemistry, preventing nutrient lockout and ensuring your plants can effectively absorb the fertilizers you provide.

Each compressed brick expands to approximately 2.5 cubic feet of ready-to-use growing medium when hydrated. This makes it a space-efficient option for storage before you are ready to start your project.

Yes, because the coir is triple-washed and steamed to ensure sterility, it is safe for use as reptile bedding. Its natural moisture retention also helps maintain the humidity levels required for many tropical terrarium species.

Absolutely. Its pH-neutral profile and excellent air-to-water ratio make it an ideal substrate for hydroponic systems. It provides the necessary structure for root development while allowing for precise nutrient control.

While the fiber structure is designed to maintain excellent aeration on its own, you can certainly mix it with perlite or vermiculite if you prefer extra drainage. For most container gardening applications, however, it performs perfectly well straight out of the bag.
