Give your plants a head start on producing better flowers by providing them with Phosphorus and Potassium from the beginning of the bloom phase. This will ensure that they have healthy roots, vigorous growth, sturdy stems and stalks, and an increased production of flowers. Start feeding your plants with Bud Blood Powder as soon as you switch to 12-hour lighting to give them the necessary P and K for a successful bloom phase and take your growing to the next level. Professional growers have reported achieving an entire extra harvest per year by using Bud Blood Powder.
