Want to take your soil from depleted to thriving? The Pro Soil Enhancer Bundle is your all-in-one solution to revitalise lawns, gardens, and crops, naturally. With Activ8Mate, Quantum H, and Stimulizer, this bundle delivers a powerful combination of organic nutrients, humic acids, and bio-stimulants that detoxify soil, feed beneficial microbes, and boost plant growth from the roots up. Whether you’re growing lush turf, vibrant veggies, or resilient trees, this is the foundation for a greener, healthier landscape, all year round.
What's inside the Pro Soil Enhancer Bundle:
Activ8mate – Liquid Fertiliser & Inoculant
Stabilises nutrients in the soil for long-term availability and balanced plant growth.
Quantum H – Premium Humic Acid Solution
Improves soil structure and nutrient cycling while detoxifying residues.
Stimulizer – Super Concentrate Bio-Stimulant
Enhances nutrient uptake, microbial activity and overall plant performance.
The science behind the Pro Soil Enhancer Bundle is centred on rebuilding soil function by targeting the three key limitations in most soils, nutrient lock-up, low microbial activity, and poor structure, all at once. This bundle combines Activ8Mate, Quantum H, and Stimulizer to create a highly efficient soil–plant system where nutrients are not just added, but actively unlocked, stabilised, and cycled.
Together, these products shift the soil from a depleted medium into a biologically active system where nutrients are continuously recycled, uptake is maximised, and plant growth is both stronger and more resilient over time.

First time owning lawn. Gave the team at plant doctor a ring and they supplied me with a wealth of information. Products turned up quickly.
Will definitely be getting more 8 weeks difference been using stimulizer, activ8mate, soil wetter, seaweed secrets and champion fertiliser. Was super fast delivery.
Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
