Jack's® Nutrients FeED 12-4-16 RO Pure Water Fertilizer

Jack's® Nutrients FeED 12-4-16 RO is a specially crafted one-part nutrient blend that caters to the needs of crops grown in very low alkalinity waters, such as reverse osmosis (RO) water, rainwater, and distilled water. This unique formula is designed for growers who prioritize purity and require a nutrient solution that is compatible with such water sources.

One of the key features of this formula is its ability to minimize pH crash. When using low alkalinity waters, maintaining a stable pH level can be challenging. However, this innovative formula is created using innovative raw materials that effectively mitigate pH fluctuations. This helps ensure that your plants receive a consistent and optimal pH environment, promoting healthy and vigorous growth.

Beyond its pH stabilizing properties, it is meticulously formulated to provide all the essential nutrients that plants require for robust growth. With a balanced composition featuring 12% nitrogen, 14% phosphorus, and 16% potassium, this nutrient blend supplies the necessary elements to support various plant functions, including root development, foliage growth, and overall plant vitality.
