HESI Hydro Bloom contains a higher concentration of phosphorus and potassium components compared to Hydro Growth. Plants have an increased need for phosphorus as well as potassium in the flowering phase in order to create strong and healthy flowers. During the first half of the bloom, this need is satisfied for 100% by HESI Hydro Bloom. In the second half of the flowering phase, HESI PK 13/14 is added together with HESI Hydro Bloom in order to fulfill the needs entirely. HESI Hydro Bloom contains a mix of vital substances that is particularly geared to the flowering phase. Composition: NPK 3 4 5 nitrogen 3.0% N, phosphorus 3.9% P2O5, potassium 5.1% K2O and other: magnesium, calcium, sulphate trace elements: iron, manganese, zinc, copper in EDTA-chelated form, boron, molybdenum plus vitamins B1, B2, B6, plant sugars and amino acids.
