Grotek Solo-Tek Bloom provides optimum nutrient ratios for prolific flowering and fruiting. A one-part bloom fertilizer that is easy to use and highly effective on a range of crops. S Highly effective as a stand-alone fertilizer; the results are even more explosive when used with supplements. Solo-Tek Bloom is a one-part base nutrient that is easy-to-use and highly effective on a range of crops. This concentrated formula was specifically designed to benefit both soil and soilless growing environments, where cation exchange occurs. In a water-based system, the benefit of a common 3-part nutrient is an immediate change in nutrient ratios, giving growers a fast reaction to the plant's needs. However, in media like peat or coco coir, this benefit doesn't have the same impact as nutrients move and bind in the soil or soilless structure, delaying interaction with plant roots. Solo-Tek Grow and Bloom were designed to counteract this, ensuring plants receive the nutrients they need, when they need it. The proprietary Solo-Tek formulations are extremely concentrated and require low application rates. High levels of humic acid ensure increased nutrient availability, and can also support beneficial biology in the soil. The nutrient profile in Solo-Tek Bloom supports flower development and growth, while improving yield. High levels of calcium support strong plant structure and heavy development. Added micronutrients support higher yield, and improved crop quality. Key Features: Enhances nutrient availability Optimized nutrient ratios for flower and fruit development Highly concentrated formula Application Rate:1L makes 500L of solution.
