The Range
Our soil test kits are designed to unlock the full potential of your garden by identifying exactly what your soil needs. Once you have your personalised soil analysis in hand, you can make targeted, effective choices using our three specialised product ranges. The HERO Range offers premium liquid fertilisers that deliver fast-acting nutrition directly to your plants for a quick boost in growth and vitality. For long-term soil improvement, the CHARGER Range features pelletised fertilisers that provide essential nutrients to support sustained health in your soil. And to fine-tune your results, our Nutrient Supplement Range can be blended with the CHARGER pellets, directly addressing all nutrient deficiencies flagged in your soil report.
Together, these products work in harmony, guided by your soil test, to create a tailored nutrition program for your garden. No more over-fertilising or guessing what’s missing. Just smart, targeted solutions that work with your soil, not against it.
