Pro-Grow Rockdust is an ancient mineral-laden volcanic rockdust, rich in nutrients to boost soil and compost whilst capturing carbon and it is sourced only from Pro-Grow Rockdust approved quarries.   PREMIUM GRADE Pro-Grow Rockdust is screened to a particle size of 0-2mm and is packaged in 500g Shaker Tubes, 10kg Printed Bags and 0.5t and 1t bulk bags.   STANDARD GRADE Pro-Grow Rockdust is screened to a particle size of 0-4mm and is available in 0.5t and 1t bulk bags only.   

This carbon capture product is based on research published by Newcastle University.

• As a 100% natural, mineral laden top dressing for soil obtained as a by-product of quarrying, Pro-Grow Rockdust is rich in macro and micro nutrients to remineralise your soil.
• 1 part by weight of Pro-Grow Rockdust can capture up to 25% by weight of the greenhouse gas Carbon dioxide (CO2).
• Via a process called “Enhanced Weathering”, CO2 is taken out of the biological cycle and locked away into the geological cycle for thousands of years.
• The nutrients in Pro-Grow Rockdust boosts the soil biology that then makes the minerals in the rockdust, and those already in the soil, more bioavailable to the plants.
• When composting, Pro-Grow Rockdust works as an activator to boost the soil biology and it also provides carbon to help balance the high nitrogen in grass cuttings, fruit & vegetable peel.
• By gardening with Pro-Grow Rockdust you are helping to combat climate change whilst improving your soil.
