B.A.C. CalMag V2.0, 5L

Essential Calcium and Magnesium Supplementation for Indoor Growing

B.A.C. CalMag V2.0 is a premium calcium, magnesium, and iron supplement specifically formulated for hydroponic and soilless cultivation systems. This advanced nutrient solution addresses one of the most common deficiencies in indoor growing - calcium and magnesium shortages that can severely impact plant health, yield quality, and overall crop performance. Whether you're growing in coco coir, rockwool, or running hydroponic systems with soft water or reverse osmosis water, CalMag V2.0 ensures your plants receive the essential secondary nutrients they need for robust development.

Key Features and Benefits

This carefully balanced formulation delivers calcium, magnesium, and iron in optimal ratios that plants can readily absorb and utilize. The inclusion of natural amino acids and trace elements enhances nutrient uptake and improves overall plant metabolism, making it an indispensable tool for serious indoor cultivators.

• High-quality calcium (5.0%) and magnesium (12.0%) blend prevents common deficiencies in hydroponic systems
• Iron DTPA chelation ensures maximum bioavailability and prevents iron lockout
• Natural amino acids boost nutrient uptake and improve plant stress resistance
• Compatible with all growing media including coco coir, rockwool, and hydroponic systems
• Essential for reverse osmosis and soft water applications where minerals are depleted
• Can be used throughout entire growth cycle from seedling to harvest
• Prevents blossom end rot in fruiting plants and improves cell wall strength

Application and Usage Guidelines

B.A.C. CalMag V2.0 is particularly valuable when using reverse osmosis water, which lacks the natural minerals that plants require. Always add CalMag V2.0 first to your reservoir before introducing base nutrients, allowing for proper mixing and pH stabilization. The standard dosage of 1ml per liter provides an excellent starting point, though experienced growers may adjust based on specific plant needs and growing conditions.

For optimal results when using RO water, add CalMag V2.0 first, mix thoroughly, then proceed with your regular hydroponic nutrient program. This product can be applied with every watering, making it ideal for both drain-to-waste and recirculating hydroponic systems. Always shake well before use and store above 8°C to maintain product stability.

Perfect for Professional and Hobbyist Growers

This supplement is ideal for hydroponic enthusiasts, commercial growers using soft water sources, and anyone growing in inert media that doesn't naturally provide calcium and magnesium. It's particularly beneficial for growers experiencing issues like interveinal chlorosis, stunted growth, or poor flower development - all classic signs of calcium and magnesium deficiency.

CalMag V2.0 pairs exceptionally well with complete hydroponic nutrient lines and works synergistically with root stimulators and beneficial microorganisms. For comprehensive growing guidance, check our detailed articles on choosing the right fertilizers and hydroponic growing for beginners.
