Humboldts Secret Base A & B Bundle is the world's best base nutrient system, as it contains a premium signature blend of Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Fulvic Acid, and other essential macronutrients. The combination of Base A & B ensures a complete feed for rapidly growing flowering plants. Our commercial-grade and garden-safe two-part base nutrient system should be used from the beginning of vegetative growth through the end of the flowering cycle. Humboldts Secret Grow & Bloom is perfectly suited for all growing mediums, including potting soil for indoor plants, hydroponics, coco, and soil cultivation. No more second-guessing! Our 2-Part Base Nutrient System is safe and easy to use. We recommend using Base A and Base B in equal parts at a rate between 5-14 ml/gallon for optimal results. You'll be happy to know that our product is not only suitable for garden plants, but for indoor plants as well! Although our Base A & B Nutrient System will provide all of the essential nutrients for growth and increased plant production, for maximum results, you can use it with our signature Golden Tree product.
