B-52 gives the plant a massive energy boost by increasing its metabolism. It also increases nutrient uptake by providing naturally occurring hormones and vitamins that the plant wouldn't otherwise get from anywhere else. Regardless of the growing medium used, whether soil or hydroponic, B-52 always works. Whether added to the nutrient tank as a foliar spray or dissolved in water, B-52 can and should be used throughout the plant's life cycle, from seedling or cutting to harvest.
