HY-GEN Cocopeat
Raw coir can make a tricky start to a coco grow. Straight from the husk it carries sodium and potassium on its exchange sites, and an unbuffered batch will pull calcium and magnesium out of your feed to replace them. HY-GEN Cocopeat deals with that before it reaches you. It's a 100% natural coir growing medium buffered with calcium and magnesium. The buffering conditions the fibre and clears out nuisance elements such as sodium, and the medium is pH stabilised to hold steady conditions around the root zone.
Why does buffering matter so much? Coir has a high cation exchange capacity. Its fibres hold onto positively charged nutrients and trade them with the solution around the roots. Load those sites with calcium and magnesium up front and the medium stops competing with your plants for them. Skip that step and calcium and magnesium shortages can turn up even when the feed is mixed right, because the coir takes its share first.
HY-GEN source their cocopeat from some of the world's largest coconut producers. Their chemist and owner developed the buffering process after reviewing internationally certified methods, and HY-GEN say each batch is regularly laboratory tested against the analysis printed on the bag, the same way the analysis is listed on every bottle of their nutrients.
In the pot it holds plenty of water, keeps a good share of air space and drains freely. It's low in salt, with no harmful chemicals added. It also naturally contains Trichoderma, a fungus that colonises the root zone, and HY-GEN say its presence helps protect against pathogens such as Pythium. That's a welcome extra. Pythium is a water mould behind a lot of root rot and damping off, and it does best in wet, warm, poorly aerated media.
It's made to work with soluble coco-specific nutrients. HY-GEN pair it with their own HY-GEN Coco Grow and Coco Bloom two-part formula and with the Cornucopia CocoGrow and CocoBloom single-part formula. HY-GEN pitch it at everyone from home gardeners to large-scale commercial growers, across a broad range of crops. Because it has no added harmful chemicals, it also makes good bedding for a worm farm!
