Boca Hydro Tomato Cal
Highly Soluble Sugar Cane-Derived Nitrogen and Calcium
for Tomatoes, Peppers & Vegetable Gardens
Boca Hydro Tomato Cal is a premium liquid calcium and nitrogen supplement formulated for tomatoes, peppers and other high-demand flowering and fruiting crops. At the center of the formula is a highly soluble, sugar cane-derived calcium source designed to disperse readily in water and provide calcium in a form that can be efficiently delivered throughout a feeding program.
Unlike calcium sources that depend on slow mineral dissolution in the soil, Tomato Cal is already formulated as a liquid concentrate. This makes it especially useful when growers need a convenient source of calcium for fertigation, soil drenches, container plants, coco coir and foliar feeding programs.
The formula supplies 16% Calcium together with 11% Nitrogen, plus magnesium, boron and zinc. This combination supports vigorous plant growth, healthy new tissue, strong cell development, chlorophyll production, flowering, fruit set and uniform fruit development.
Tomato Cal is especially useful during periods of rapid vegetative growth, flowering and early fruit development when calcium demand can increase dramatically.
Highly Soluble Calcium for Rapidly Growing Plants
Calcium is essential to plant growth, but simply having calcium present in the soil does not always mean the plant can obtain enough of it. Many traditional calcium materials dissolve slowly or depend heavily on soil chemistry, moisture and pH before meaningful amounts become available.
Boca Hydro Tomato Cal is designed to overcome that limitation with a concentrated liquid source of highly soluble calcium.
Because the calcium is already dispersed in a liquid formulation, Tomato Cal can be mixed directly into irrigation water and distributed throughout the active root zone. This is especially valuable for fast-growing crops with high calcium demand.
High solubility makes Tomato Cal an excellent choice for:
- Tomatoes producing rapidly expanding fruit
- Peppers during flowering and fruit development
- Eggplant, cucumber, squash and melons
- Container-grown vegetables
- Coco coir and soilless growing media
- Raised beds and intensive vegetable gardens
- Fertigation and drip irrigation programs
- Plants showing increased calcium demand during rapid growth
Why Calcium Matters
Calcium is a structural nutrient. Plants use it to build and stabilize cell walls and membranes, making it especially important in rapidly expanding leaves, roots, flowers and fruit.
Unlike highly mobile nutrients such as nitrogen or potassium, calcium has limited mobility once deposited within plant tissue. New growth therefore depends heavily on a continuous supply of calcium reaching actively growing tissues.
Maintaining consistent calcium availability helps support:
- Strong cell wall formation
- Healthy growing tips and young leaves
- Firm stems and plant structure
- Normal flower and fruit development
- Uniform fruit formation
- Improved tissue strength
- Healthy root development
Support Against Blossom End Rot
Blossom end rot is closely associated with insufficient calcium reaching rapidly developing fruit tissue. Tomatoes, peppers, eggplants, squash and similar crops can be particularly susceptible when calcium delivery becomes inconsistent.
Environmental conditions can also influence calcium movement. Irregular watering, damaged roots, excessive salinity, rapid growth and extreme heat can all interfere with the plant's ability to move calcium to developing fruit.
Tomato Cal provides a concentrated, highly soluble calcium source that can be incorporated into a consistent irrigation and nutrition program to help maintain calcium availability during the periods when plants need it most.
Naturally Derived from Sugar Cane
Tomato Cal's calcium source is derived from sugar cane-based organic material, giving growers an alternative to conventional mineral-only calcium supplements.
The sugar cane-derived organic components help create a highly soluble liquid formulation that mixes easily into water and can be distributed evenly throughout the root zone.
For growers using soil, potting mixes or coco coir, this provides a convenient way to supplement calcium without depending entirely on slow-release limestone, gypsum or other solid calcium amendments.
The result is a versatile calcium product that combines the convenience of a liquid concentrate with a naturally derived calcium source.
More Than Calcium
Tomato Cal combines calcium with several complementary nutrients important to productive vegetable and fruit crops.
Designed for Heavy-Feeding Fruiting Crops
Tomatoes may be in the name, but Tomato Cal can be used with a wide range of crops that require consistent calcium nutrition.
Ideal for Soil, Containers, Coco & Fertigation
Tomato Cal is designed for flexible application across several growing systems.
Soil Gardens & Raised Beds
Apply through irrigation or as a soil drench to supplement the calcium already present in the soil.
Pots & Containers
Container plants have a limited nutrient reserve and can benefit from regular supplementation throughout periods of active growth.
Coco Coir & Soilless Media
Coco and other soilless substrates contain little natural nutrient reserve, making a consistent calcium supply especially important.
Fertigation & Drip Irrigation
The liquid, water-dispersible formula makes Tomato Cal easy to incorporate into irrigation programs for efficient root-zone delivery.
Foliar Application
Tomato Cal may also be used as a foliar supplement when a targeted foliar application is appropriate. Apply as a fine mist during cooler parts of the day.
General Application Guidelines
Foliar Spray
Maintenance: 1–2 teaspoons per gallon of water
Deficiency Support: 1–1.5 tablespoons per gallon of water
Apply as a fine mist during the early morning or late afternoon. Avoid spraying during excessive heat or intense direct sunlight.
Pots & Containers
Small Pots: 1–1.5 teaspoons per gallon
Medium Pots: 2–3 teaspoons per gallon
Large Pots: 1–1.5 tablespoons per gallon
Soil Drench
Light Feeding: 2–3 tablespoons per 5 gallons of water
Heavy Feeding: 4–5 tablespoons per 5 gallons of water
Fertigation — 1:100 Injector
For an application equivalent to approximately 1 tablespoon of Tomato Cal per gallon of final irrigation water, add 50 fluid ounces of Tomato Cal to the stock tank and bring the total stock volume to 1 gallon. Inject at 1:100.
Application requirements vary with crop, plant size, growth stage, growing media, source water and existing fertility. Begin with the lower rate when introducing the product into a new feeding program.
