Thrive Alive B-1 Green (1 L)
Natural Tonic for Tranplants
Keeping plants healthy through all stages of growth requires consistent nutrition and support, and a balanced plant tonic can help boost resilience while encouraging vigorous growth. Thrive Alive B-1 Green is a preventative and restorative formula enriched with vitamins and nutrients derived from sea kelp, making it suitable for use throughout the plant’s life cycle.
This versatile tonic works in both hydroponic and soil-based systems, delivering a steady supply of nutrients to support rooting, vegetative growth, and recovery from stress. Its sea kelp base provides natural compounds that promote root development, increase tolerance to environmental challenges, and enhance overall plant vitality. It’s especially useful for reducing transplant shock—simply soak roots before planting to help seedlings and transplants establish quickly.
Thrive Alive B-1 Green can be applied as a foliar spray for rapid nutrient absorption or used as a root soak during transplanting. Gentle yet effective, it’s easy to incorporate into your regular feeding schedule and is compatible with a wide range of growing setups.
