What is it?

Soft rock phosphate (SRP) is a mineral powder phosphate source, that provides a long lasting, slow release source of phosphate that can be applied in a variety of ways. It can be top-dressed, mixed into your soil or even used as a 'spike'.
 

What are the benefits?

SRP does not leach nutrients over time. Furthermore SRP is also a great mineral to increase the tilth and improve overall structure of the soil.  SRP has an abundant source of trace elements, which assist your plants to grow and function at their optimal activity. With 9% Phosphorus 25% Silica and 19% Calcium you have three of the major elements needed for a fast and productive flower period, allowing your plants to reach their full potential.
 

How do I apply?

We recommend a rate of 1.5 cups per 75L of growing medium for a first application and another 1/4 cup each subsequent cycle depending on your nutrient demands.
