This blend has no additional nutrients apart from our base amendment mixture. The performance of the Formula1 blend depends on the application of available nutrients in the form of a balanced inorganic nutrient formulation. Application is required with the first watering and subsequent additions according to the plant’s requirement.  A leaching requirement or runoff is necessary with every other nutrient application to avoid salt build-up. Water scheduling for this soil will require more regular watering when opting for fast growth.


  • Ideal for container growing
  • Indoor or Greenhouse cultivation
  • High intensity production with automated fertigation
  • Balanced nutrient solution input essential

Ideal watering pH for Freedom Farms Craft Soils: 5.5 – 6.0

Pure coconut coir has a pH between 5.8 – 6.8. A substrate/soil pH of between 5.5 and 6.5 is ideal for plant nutrient uptake under both organic and inorganic fertiliser regimes. Freedom Farms Coco coir is buffered and charged with natural amendments. The high Calcium content of our amendments maintains the pH in the 6.5-6.8 range and will prevent a decrease in pH (substrate acidification) resulting from fertiliser application or waterings at a low pH. The soil pH is therefore buffered against decreasing pH. On the other hand, an incremental increase in pH resulting from tap water (pH 7-8.5) use can cause the soil pH to increase above the optimal range for nutrient uptake. The soil pH is therefore not buffered against increasing pH caused by using un-pH’d tap water. Watering with a pH of 5.5-6.0 will ensure the pH of the soil remains in the optimal range of 5.5-6.5.
