A plant growth medium composition and production process thereof is provided. The growth medium composition comprises a coconut coir pith and one or more additives mixed into the coconut coir pith processed into a formed growth medium suitable for facilitating the growth of one or more plants. The production process comprises the steps of cracking, dehusking, and removing the meat from the whole coconut. The coconut coir is then washed and mulched, and an additive mixture is mixed with the coconut coir pith. The coconut coir pith and additive mixture is processed into a desired form, and the additive mixture is applied to the exterior surface thereof. The final product is then packaged before being transported to a horticulturist.

A passive nutrient delivery system for plant growth includes a rooting module having a body portion having a top, a bottom, and a sidewall extending between the top and the bottom. The rooting module further includes a hydrophilic plug, having an opening, in a first portion of the interior of the body portion adjacent the top of the body portion, and a substrate in a second portion of the interior of the body portion between the bottom and the plug. The rooting module further includes an oxygen permeable area in the sidewall of the body portion, a first wicking material extending through the sidewall of the body portion into the interior of the body portion, and a second wicking material extending through the body of the body portion into the interior of the body portion, through the interior of the body portion, and through the opening of the plug. The passive nutrient delivery system also comprises a reservoir wherein a port can receive the removable rooting module.
