🌿 WATER-SOLUBLE CALCIUM (WCA)

A KNF-Inspired, Organic Calcium Solution for Healthier, Stronger Plants

Water-Soluble Calcium (WCA) is a fast-acting, bioavailable calcium supplement designed to support plant structure, nutrient uptake, and overall vitality.

Made popular by Korean Natural Farming (KNF), this organic, chloride-free, and nitrate-free formulation is crafted through a natural chelation process that combines calcium carbonate with acetic acid and water. It provides an immediate source of calcium while also delivering organic acids and a trace amount of boron, further enhancing plant development.

🌱 WHY USE WATER-SOLUBLE CALCIUM?

Strengthens Plant Cell Walls
Improves fruit and vegetable structure, reducing issues like blossom end rot.
Boosts Nutrient Uptake
Calcium enhances the absorption of potassium and magnesium, supporting overall plant health.
Supports Fruit & Seed Development
Boron plays a key role in pollination, fruit set, and reproductive success.
Organic & KNF-Approved
A natural alternative to calcium chloride and calcium nitrate, ensuring a safer, more sustainable approach to plant nutrition.

🍅 IDEAL FOR FRUITS & VEGETABLES

This fast-absorbing calcium blend is particularly beneficial for crops such as:

Tomatoes, Peppers & Cucumbers
Helps prevent blossom end rot and strengthens fruit structure.
Berries & Orchards
Improves fruit quality, shelf life, and resistance to environmental stress.

🌿 PERFECT FOR CANNABIS CULTIVATION

Maximizes Nutrient Uptake
Essential for proper magnesium and potassium absorption, preventing nutrient lockout.
Strengthens Cell Walls
Promotes resilient, disease-resistant plants with better structural integrity.
Increases Yields
Encourages vigorous root growth and stronger plant development, leading to higher-quality cannabis.
Enhances Smoking Quality
Proper calcium levels contribute to a cleaner, smoother burn, helping produce the white ash that signals a well-cured, high-quality cannabis product.

🌾 HOW TO USE

Foliar Spray
Mix 10–20 mL per litre of water. Apply in the early morning or late evening to avoid direct light.
Recommended application: 1–4 litres per acre.
Soil Drench
Mix 5–10 mL per litre of water and apply to saturate the soil around the plant's drip line.
Recommended application: 1–4 litres per acre.
Blossom End Rot Prevention
Apply every 7 days during periods of rapid growth or heavy rainfall. Otherwise, apply bi-weekly or monthly as needed.
