SUPERthrive is a well-known plant supplement brand trusted by growers and gardeners for supporting healthier roots, stronger plants and improved recovery during periods of stress. Originally developed in 1940, SUPERthrive's vitamin and kelp-based formula has become a popular addition to growing programmes around the world.

Unlike traditional NPK fertilisers, SUPERthrive is designed as a plant health supplement that works alongside your existing nutrient programme. It is commonly used during transplanting, propagation and periods when plants need additional support. Suitable for indoor gardens, hydroponic systems and container-grown plants, SUPERthrive provides a simple way to complement a complete growing setup.
