Jack's Elementals® Calcium Chloride Dihydrate 1lb

Jack's Elementals™ Calcium Chloride Dihydrate -- Soluble Calcium Supplement

Jack's Elementals™ Calcium Chloride Dihydrate is a highly pure, rapidly soluble calcium source formulated for use in hydroponic and soil growing environments where calcium supplementation is required. Calcium is a critical secondary macronutrient that plays an essential role in cell wall formation, cell division, enzyme activation, and the structural integrity of plant tissue. Calcium deficiency is one of the most common nutrient imbalances encountered in indoor growing environments, particularly in rapidly growing plants with high metabolic demands.

The dihydrate form of calcium chloride dissolves quickly and completely in water, making it an ideal precision supplement for growers who need to fine-tune their calcium levels in nutrient solutions without introducing unwanted companion ions from less pure calcium sources.

Key Features & Benefits

• High Solubility: Dissolves rapidly and completely in water, providing immediate calcium availability without sedimentation or system clogging.
• Targeted Calcium Supplementation: Provides a direct source of calcium ions for rapid correction of deficiency symptoms including tip burn, blossom end rot, and distorted new growth.
• Cell Wall & Structural Support: Calcium is fundamental to the formation of pectin cross-links in plant cell walls, supporting firm, structurally sound tissue.
• Enzyme Activation: Calcium acts as a cofactor for numerous plant enzymes and is involved in cell signaling pathways.
• Precision Dosing -- 1lb Format: Ideal for growers who need precise, measured supplementation rather than bulk quantities.

Who Should Use This

Jack's Elementals™ Calcium Chloride Dihydrate is ideal for hydroponic growers who build their own custom nutrient formulas and need a high-purity calcium source, as well as soil growers experiencing calcium deficiency symptoms during vigorous vegetative growth or early flowering.

Compatibility

Compatible with most hydroponic nutrient formulas. Note that calcium chloride introduces chloride ions alongside calcium -- growers with chloride-sensitive crops should consider this when calculating total chloride load. Avoid mixing concentrated calcium chloride solutions directly with concentrated sulfate or phosphate solutions to prevent precipitation.

Frequently Asked Questions

What are the signs of calcium deficiency in plants?

Common calcium deficiency symptoms include tip burn on leaves, necrotic leaf margins on young leaves, distorted or cupped new growth, blossom end rot in fruiting crops, and soft or weak stem tissue. Deficiency typically appears first on the youngest, fastest-growing plant parts.

How does Calcium Chloride Dihydrate differ from calcium nitrate?

Calcium Chloride Dihydrate provides calcium alongside chloride ions, while calcium nitrate provides calcium alongside nitrate (nitrogen). If additional nitrogen is not desirable in your feeding program, calcium chloride is the preferred option for targeted calcium correction.

Can I use this product in soil as well as hydroponics?

Yes -- Calcium Chloride Dihydrate can be dissolved in water and applied as a soil drench or foliar spray in soil-based growing environments. Start with low application rates and adjust based on plant response.

How do I measure and dissolve this product correctly?

Measure by weight for precision, then dissolve in a measured volume of water before adding to your reservoir or nutrient solution. Always add the dissolved solution to a diluted nutrient tank rather than concentrated stock solutions.
