Heavy 16 Foliar Spray embodies the brand's philosophy of more science, fewer bottles. This 1-gallon concentrate uses a powerful combination of mineral and natural ingredients in a system that is straightforward to apply and maintain. Applied directly to leaves, it improves overall plant nutrition, corrects calcium and magnesium-based plant disorders, and improves tolerance of abiotic stress like heat and environmental swings.

Foliar feeding delivers nutrients through the leaf surface for rapid uptake, making it an effective way to correct deficiencies quickly while supporting steady growth. The gallon size keeps larger rooms and frequent spray programs stocked without constant reordering.
