Standard Grade
Recommended for use in medium/soft water areas, where the background alkalinity (bicarbonate content) is between 50 & 150 mg/litre.
Extra Grade
An acid mix containing Urea Phosphate. Recommended for use in hard water areas (bicarbonate content of +150 mg/litre), as the acid stock solution helps improve trace element availability and helps prevent blockage of dripper nozzles. Also reduces expensive acid dosing.
High Nitrate Grade
Recommended for use in very soft water areas (bicarbonate content of 0-50 mg/litre); especially for seedlings, young plants and Ammonium sensitive sp. such as Antirrhinum, Begonia, Impatiens, Petunia, Poinsettia, and St.Paulia.
The high level of Nitrate-N increases Calcium and dry matter accumulation giving stronger healthier plants than where a high proportion of Nitrogen is in the Ammonium form.
