The Sensi Bloom A+B Pro 10 kg basic food from Advanced Nutrients is specially developed for hydroponic systems such as aeroponics, drip irrigation, NFT, ebb & flow or deep water culture. Unlike conventional fertilizers, the Sensi Professional Series offers precise micronutrient ratios for each growth phase of the plants. During growth, plants absorb more calcium, iron, manganese and boron, while they require less nitrogen, potassium, zinc and phosphorus. In the flowering phase, the needs change, with plants taking up more nitrogen, potassium and zinc. The series continuously supplies easily available nutrients thanks to three forms of chelated iron and urea for acidic rhizosphere. The dosage table can be found in the photo gallery or the attached files. This set contains 10 kg of component A and 10 kg of component B.
