NPK Industries RAW Calcium/Mag - 25 lb

Water Soluble Calcium and Magnesium for Steady Feeding - 25 lb

Calcium and magnesium shortfalls slow growth, and heavy correction can leave media salty. RAW Calcium/Mag combines calcium nitrate and magnesium sulfate in a water soluble formulation with a balanced ratio of the two elements, so you can prevent or treat deficiencies without building up salts in the media. It runs at low dilution rates, so a little goes a long way.

The 25 lb unit suits growers who feed regularly and want a stand-alone supplement on hand. It fits indoor growers running recurring feeding schedules and commercial rooms that mix their own recipe solutions.

Key Features & Benefits

• Calcium nitrate and magnesium sulfate — two sources of calcium and magnesium in one water soluble powder.
• Balanced ratio — designed so it does not leave the media salty.
• Low dilution rates — a small amount treats a reservoir, which stretches the 25 lb unit.
• Stand-alone supplement — adds calcium and magnesium without replacing your base nutrients.
• Works with feeding programs — suits hydroponic systems and soil-based cultivation.

Who Should Use NPK RAW Calcium/Mag

Use it if you grow in hydroponic systems or soil and need to prevent or correct calcium and magnesium deficiencies, or if you build custom recipe solutions and want a dedicated calcium and magnesium input.
