Global Supply Phosphorus is found in small concentrations but wide distribution in the entire Earth’s crust. However, free phosphorus doesn’t exist on the Earth’s crust, due to it being highly reactive. Mined phosphate fertilizer reserves have been estimated to last at least until the year 2300, with 80% of the global phosphorus supply located in Morocco and Western Sahara. Due to recent global conflicts,...

Coconut coir is a byproduct of the coconut industry, being used for the production of coconut oil, juice, and flesh (or “meat”). These are produced from coconut palm trees. As with most fruits, coconuts contain large amounts of potassium. The coconut husk is essentially a lignin compound, similar to wood, but evolved to be more resilient as it protects the reproductive part of the...

  Coco coir differs from other substrates in many ways, but one big difference is the anion capacity. What does this mean for nitrogen levels in your nutrient solution? The overall level of nitrogen in your nutrient solution should be based on the plant's need for nitrogen, which is dictated by the amount of photon energy received by the leaves. Higher PPFD levels mean...
