Buystar Extra ACID is the innovative line of fertigation that arises from an accurate and constant search for new solutions to market demands, increasingly attentive to the quality of the formulations and environmental sustainability. The products of the Buystar Extra ACID line are characterized by raw materials of extreme purity and acid pH. In addition, they are distinguished by the ability to reduce the amount of bicarbonate ions present in the nutrient solution and to increase exponentially the amount of nutrients absorbed. Finally, the presence of RyZea, the natural activator of plant metabolism, enriches the formulations of components capable of stimulating the growth and development of the plant, ensuring high yields and increasing resistance to adversity.
