  • Perlite – an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. Perlite has excellent “wicking” action yet doesn’t absorb water giving the plants roots plenty of oxygen. Commonly used in a mixture with vermiculite or Coco Peat, but can also be mixed into finer grading of composted pine bark to give the medium excellent aeration and drainage capability. It is an organic agricultural material and is listed as such by the Organic Materials Review Institute (https://www.omri.org/).
  • Composted pine bark – It’s important that you know where the raw materials used in your compost comes from. It ensures the elimination of harmful contaminants and pathogens being introduced into your growing system. Urbz recommends the use of composted pine bark sourced from Bark Unlimited Organics. Our speciality mix comprises of a 60% ratio of 8mm graded composted pine bark, mixed with a 40% ratio of perlite. This mix is definitely suited to the more traditional “organic” gardener who enjoys interacting with earth when planting.



The growing of plants in nutrient solutions, with/without sand, or other inert media, to provide support to the plant. All of the nutrition required by the plants comes from water soluble nutrients in place of the soil.


Hydroponics has proved to have several advantages over soil gardening;

  • Fewer Pesticides – While pests are not completely absent in hydroponics systems, the closed, controlled environment eliminates many of the pesticides that are often necessary to keep bugs from destroying plants. This means less poison on plants, in rivers, and more importantly, on the food we eat.
  • The growth rate on a hydroponic plant is 30-50 percent faster than a soil plant, grown under the same conditions.
  • Greater yield.
  • Hydroponic gardening uses considerably less water than normal soil gardening.
  • Since hydroponic gardening systems use no topsoil, topsoil erosion isn’t even an issue.
