Super phosphoric acid is produced from phosphates by reacting with sulphuric acid. The acid is reacted with alkaline salts to produce purified phosphates. Plants need phosphorus and phosphorus-containing compounds as they play a vital role in photosynthesis. Super phosphoric acid also aids in root development and helps increase the uptake of iron, nitrogen and potassium. Cyco XL used in the early stages of growth (not recommended before week 3) of a plant's growth stage will help with the uptake of the above mentioned elements and increase root growth rapidly. Any increase in root growth will increase the amount of root hairs on your plant to allow for more absorption of water and nutrients.
