Botanicare Cal-Mag Plus - 1 Gal

Calcium and Magnesium Support for Fast-Growing Plants - 1 Gal

Reverse osmosis water and coco coir start with little calcium, and fast-growing plants quickly show the shortfall. This supplement adds calcium, magnesium and iron to your nutrient solution so you can correct and help prevent deficiencies. The guaranteed analysis reads Nitrogen 2.0%, Calcium 3.2%, Magnesium 1.2% and Iron 0.1%.

The 1 Gal bottle suits growers who run a regular indoor schedule and want a steady supply for repeated waterings. Because the label dose is 1 tsp (5 ml) per gallon of water, one bottle covers many reservoir fills.

Key Features & Benefits

• Calcium, magnesium and iron in one bottle — adds the three minerals together instead of dosing them separately.
• Low dose rate — 1 tsp (5 ml) per gallon of water keeps each batch economical.
• Foliar option — can also be applied as a foliar spray at 10 – 15 ml per gallon.
• Fits several systems — used in hydroponic, soil and container setups alongside your preferred nutrient program.

Who Should Use Botanicare Cal-Mag Plus

Growers who water with reverse osmosis water, grow in coco coir, or see signs of calcium and magnesium shortage in fast-growing plants. Home gardeners and licensed commercial operations can both use it within an existing nutrient program.

A: Yes. The label gives a foliar rate of 10 – 15 ml per gallon of water. Mix well before spraying.

Q: Why add calcium and magnesium to reverse osmosis water?
A: Reverse osmosis removes most dissolved minerals, including calcium and magnesium. A supplement restores them so plants have a balanced supply.

Q: What does guaranteed analysis mean?
A: It is the minimum nutrient content the maker states on the label, shown as a percentage. Here it covers nitrogen, calcium, magnesium and iron.
