Our Premium Ingredients

Rhizophagus irregularis: The Root Enhancer

This beneficial fungus, formerly known as Glomus intraradices, forms a symbiotic relationship with plant roots, vastly improving nutrient and water uptake. It significantly increases the root surface area, aiding in the efficient absorption of phosphorus, a critical nutrient for plant growth and flowering.

Bacillus subtilis: The Protective Warrior

Bacillus subtilis is a well-known probiotic bacteria that offers a dual benefit. It not only enhances nutrient absorption but also protects plants from harmful pathogens. This bacteria strengthens the plant’s immune system, making it more resilient against diseases and environmental stresses.

Trichoderma harzianum: The Growth Stimulator

Trichoderma harzianum is a soil fungus known for its ability to improve soil structure and nutrient availability. It promotes root growth and development, enhances nutrient cycling in the soil, and helps in the decomposition of organic matter, making nutrients more accessible to plants.

Beauveria bassiana: The Natural Guardian

Beauveria bassiana acts as a natural insecticide, targeting various insect pests without harming the plants or beneficial insects. This fungus infects and controls a wide range of insect pests, thereby reducing the need for chemical pesticides and fostering a healthier, more sustainable garden environment.

100% Organic-Based Microbe Food: The Nutrient Booster

This blend of organic matter provides the essential food source for the beneficial microbes in Root Roids. It ensures the longevity and efficacy of the microbes, thereby continuously supporting soil health.
