Advanced Nutrients Sensi One Bloom is the first powdered concentrate specifically designed for dichotomous short day flowering plants. Sensi One Bloom has been thoroughly field tested and that field testing has produced a 1 part powdered nutrient that gives consistent heavy yields. Extensive research (weekly tissue samples) has produced a product that has the exact and precise ratios of macronutrients and micronutrients. Sensi One Bloom uses nutrient components that are not found in any other 1 part powdered nutrient. Our research and development team found that these additional components make an enormous difference on how your plants will bloom during the flowering cycle, compared to the other 1 part powdered nutrients.
