Most coco based products are washed in salt water so removing those salts is paramount. Make sure to rinse it several times. Also, keep in mind that coco is inert and used by hydroponics growers for just this reason. So, this means that you have to add nutrients to it or to your feeding solution. Most hydroponics growers pre-charge the coco with a Cal-Mag and fertilizer, letting it dry out a bit before transplanting.
