Product description
Supreme CalMag 5 L – calcium-magnesium plant nutrient additive for soft and RO water
Growing on reverse osmosis or very soft tap water means your plants start with almost no calcium or magnesium in the tank. Supreme CalMag fixes that at the source: you bring your base water up first, then add your normal nutrients, and the Ca/Mg balance stays right from cutting to harvest.
How far 5 L goes
For normal use you add 0.1–0.5 ml per litre until the water reaches EC 0.4 mS/cm. At those doses, 5 L is enough for 10,000 to 50,000 L of water. Even if your plants need the higher dose of 0.5–1 ml/L for a while, the can lasts several cycles in one or two tents.
Dosing routine
Fill your can or reservoir with RO or soft water, add CalMag in small steps and measure until the meter shows 0.4. Note how many ml that took for your volume; next time you can dose straight away. Then add base nutrients and additives as usual.
Safety
This product causes serious eye damage (H318). Wear eye protection and gloves when you pour or measure, and rinse thoroughly with water if it splashes.
