A concentrated growth enhancer, Humboldt Nutrients Sea Cal is suitable for any type of vegetable, flower or herb. With a carefully balanced ratio of nitrogen and calcium, use it for hydroponics and all growing medium to aid the early development of the plant. When combined with a complete nutrient feeding schedule, Sea Cal can help ensure maximum flower production, improved plant structure and reward growers with heavy fruit yields. Sea Cal can be used as a root or foliar feed. When used as a spray, calcium can be absorbed efficiently, promoting healthy mould-free leaves. Calcium is very important during the growth and flowering cycle of a plant, controlling aspects of cell wall structure and permeability, enabling the plant to absorb other nutrients effectively. Containing 2% nitrogen and 3% calcium, Sea Cal also contains 0.5% humic acid.
