Jack's Professional 15-5-15 Cal-Mag Lx

Brand: Jack's

Jack's Professional is JR Peters' water-soluble range for commercial growers - over 60 stock formulas developed through years of testing in their own laboratory and commercial facilities. They are concentrated powders built for high-output powder injector systems, and formulated to go into true solution so the nutrients stay available rather than dropping out in the stock tank.

Jack's Professional 15-5-15 Cal-Mag Lx is carries supplemental calcium and magnesium for crops or water sources short on both, supplied at a 15-5-15 analysis.

The LX system carries a peat-lite micronutrient package balanced across the whole product line, so a consistent micronutrient level is supplied even when products are tank-mixed or rotated.
