Cyco Bloom A Platinum Series Cyco Bloom A is the first of two parts to make up the base nutrient system for the flowering stages of a plants growth. Cyco Platinum Series Bloom A is a primary source of pharmaceutical grade nitrates which are vital for photosynthesis, the making of amino acids, enzymatic formation, and cell division. With pharmaceutical grade ingredients, Cyco Platinum Series Bloom A provides certifiably the cleanest form of this crucial component to plant growth. Bloom A also contains considerable amounts of calcium. Calcium in Cyco Bloom A is derived from pharmaceutical grade calcium nitrate for a source of readily available calcium to form cell walls enabling healthy plants. Cyco Bloom B Platinum Series Cyco Bloom B is the second of the two parts to make up the base nutrient system for the flowering stages of a plants growth. Cyco Platinum Series Bloom B is a primary source of pharmaceutical grade phosphorous and potassium which are vital for photosynthesis. Phosphorus is a vital component in manufacturing adenosine triphosphate, a primary unit of energy manufactured by photosynthesis that is then consumed by the plant to carry out necessary metabolic functions. Bloom B is the primary source of potassium in the Cyco Bloom range which is crucial to sustain plant growth by working to aid in photosynthesis. It also aids in the translocation of sugars throughout the plant and works to reduce unnecessary water loss and wilting.
