Grow Pharm - Coco Coir Blocks 5kg 60 - 70 Litres each


Coco Coir (pronunciation: /?k???/ - coyercomes from coconuts! It is an inert medium, meaning that you have the freedom to decide exactly what goes into it. Grow Pharm strongly recommends using a Cal-Mag with your coco to avoid deficiencies and to stabilize your pH. We also recommend that you check your pH often when using this medium, as it tends to trend up as the substrate dries. 

Grow Pharm Coco Coir is a high quality, low sodium growing medium is an environmentally friendly alternative to sphagnum peat moss and is exclusively distributed in Canada by MegaMass. When hydrated with water, bricks, and blocks rapidly expand which saves you time and effort. They can be exclusively used by themselves, blended together or mixed with expanded clay pellets, perlite or topsoil. The product will biodegrade, returning to the earth in three years.

Better still, you can run it through a chipper and amend your soil with it. Incredibly strong, it makes a better candidate for use with enzyme products that convert roots to biomass.
