What's Included

Humboldt Nutrients Sea Cal


Humboldt Nutrients Sea Cal was designed as a powerful additive for hydroponics and all growing mediums. Sea Cal may be utilized for any type of vegetable, flower, or herb. Sea Cal is a highly concentrated growth enhancer and calcium supplement that offers vital nitrogen and calcium in the specific ratios necessary during early plant development. Calcium is very important during a plant's vegetative and flowering cycle, controlling aspects of cell wall structure and permeability. Calcium is absorbed into a plant through the root tips, but plants are not always able to completely satisfy their need for calcium through their roots. Sea Cal also contains potassium silicate and humic acid. By thickening and strengthening cell walls, potassium silicate protects plants from extreme temperatures, plant stress, harmful fungi and dangerous pathogens. Potassium Silicate is to plant tissue as calcium is to strong bones. With Sea Cal, your garden is less susceptible to plant stress due to temperature. Sea Cal is available in three different size options: 1 gallon, 32 ounces, 16 ounces, and 8 ounces.
