Skyhigh Cal Mag Grow & Bloom Calcium & Magnesium Supplement

Support stronger growth, healthier development, and heavier harvests with Skyhigh Cal Mag Grow & Bloom, available from Holland Horticulture. Developed using advanced plant-derived calcium technology, this premium calcium and magnesium supplement delivers highly bioavailable nutrients that help prevent deficiencies while supporting vigorous growth and exceptional flowering performance.

Advanced Calcium & Magnesium Nutrition

Skyhigh Cal Mag products are designed to provide essential calcium and magnesium in forms that are easier for plants to absorb and utilise. Calcium supports strong cell wall development, nutrient transport, and root health, while magnesium plays a critical role in chlorophyll production and photosynthesis.

Together, these nutrients help maintain healthy plant growth, improve nutrient uptake, and maximise crop performance throughout the entire growing cycle.

Skyhigh Cal Mag Grow

Cal Mag Grow has been specifically formulated to support plants during the vegetative stage. Using a unique stabilised amine nitrogen source, this innovative formula requires significantly less energy for plants to process compared to conventional nitrate-based products.

This efficient nitrogen source promotes compact growth, shorter internodal spacing, and a more uniform canopy structure. Improved canopy development helps maximise light penetration and encourages stronger overall plant performance.

• Supports vigorous vegetative growth
• Improves root development and nutrient uptake
• Promotes tighter internodal spacing
• Encourages uniform canopy formation
• Enhances flower site initiation

Skyhigh Cal Mag Bloom

Cal Mag Bloom is a specialised flowering formula designed to maximise nutrient mobility and support heavy flower development. Plant-derived calcium is combined with synergistic boron to improve nutrient transport throughout the plant, helping to reduce deficiencies and improve flowering performance.

Unlike traditional calcium and magnesium supplements, Cal Mag Bloom is nitrate-free and enriched with amino acids, plant extracts, surfactants, and phenolic compounds. These ingredients work together to promote bulk formation, increase flower density, and enhance secondary metabolite production.

The result is improved flavour, aroma, resin production, and crop quality while supporting faster maturation and healthier flowering plants.

• Plant-derived calcium for superior bioavailability
• Added boron for enhanced nutrient movement
• Nitrate-free flowering formula
• Supports flower density and bulk development
• Enhances flavour, aroma and crop quality

Anti-Stress Plant Protection

Skyhigh Cal Mag Bloom contains antioxidant and anti-stress compounds that help plants cope with environmental pressures including intense lighting and UV exposure. These protective ingredients support healthier plant development while encouraging clean, high-quality harvests.
