Freedom Farms Premium Classic Organic Potting Mix 30L

Freedom Farms Premium Classic Growing Medium - 30L

Ideal for container growing, indoor, greenhouse or outdoor cultivation, especially the cultivation of organic medicinal-grade CBD plants. Perfectly aerated for optimum oxygen exposure. 

The Classic blend is formulated mainly for organic growing and organic nutrients. Compared to the Formula 1 mix, the Classic has a greater cation exchange capacity (CEC), higher active organic matter content, as well as a balanced semi-slow release organic nutrient component. It will also hold water longer than the Formula1 mix. Substrate pH 6.5.

First watering can either be clean water or, for hungrier plants, add a single recommended dose of organic nutrients. The nutrients in the soil should be adequate for about 2 - 6 weeks before additional nutrients are required.

Ideal watering pH for Freedom Farms Craft Soils: Ideal pH 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 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 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.
