Cyco Grow A Platinum SeriesCyco Grow A is the first of two parts to make up the base nutrient system for the vegetative growth stage of plant growth.Cyco Platinum Series Grow A is a primary source of pharmaceutical grade nitrates which are vital for leaf growth, the formation of chlorophyll, and nucleic acids which form the very DNA of the plant cells derived from pharmaceutical grade ingredients. Cyco Platinum Series Grow A provides certifiably the cleanest form of this crucial component to plant growth. Grow A is also the primary source of calcium in the vegetative stages. Calcium in Cyco Grow A is derived from pharmaceutical grade calcium nitrate for a source of readily available calcium to form thicker cell walls enabling strong stem, leaf, and stalk formation. Cyco Grow B Platinum SeriesCyco Grow B is the second of the two parts to make up the base nutrient system for the vegetative stage of plant growth.Cyco Platinum Series Grow B is an additional source of pharmaceutical grade nitrates which are vital for leaf growth, the formation of chlorophyll, and nucleic acids which form the very DNA of the plant cells derived from pharmaceutical grade ingredients.Cyco Platinum Series Grow B provides certifiably the cleanest form of this crucial component to plant growth.Grow B is diverse in its makeup in that it also provides sources of potassium, phosphorus, and magnesium completing the vital nutrients needed for plant growth.
