Mineral calcium & magnesium granules for autoflowering plants

Strong plants start with the right supply of calcium and magnesium

POWERCALMAG was developed specifically for the needs of modern autoflowering plants. The high-quality combination of natural calcium carbonate and magnesium carbonate supports stable plant development, strong cell structures and optimal photosynthesis throughout the entire life cycle.

Calcium and magnesium requirements increase significantly, particularly under powerful LED lighting or in fast-growing plants. POWERCALMAG helps prevent deficiency symptoms and optimize nutrient uptake.

Why POWERCALMAG?

✅ Provides valuable calcium and magnesium from natural sources

✅ Supports strong cell structures and stable plants

✅ Promotes healthy photosynthesis

✅ Optimizes the calcium-to-magnesium ratio in the growing medium

✅ Slow and continuous release

✅ Easy to apply by mixing in, top dressing or repotting

✅ Ideal for autoflowering plants

✅ Perfectly suited to soil and pre-fertilized growing media

✅ Suitable for AutoPot and other passive watering systems. POWERCALMAG is applied directly to the growing medium and supports a continuous supply of calcium and magnesium without putting a strain on the water reservoir.

The perfect addition to POWERMIX

For maximum results, we recommend combining it with POWERMIX.

While POWERMIX supplies the plant with essential primary nutrients, POWERCALMAG specifically provides calcium and magnesium for balanced plant nutrition.

The combination supports:

• strong roots
• stable plant structures
• improved nutrient uptake
• healthy leaf development
• maximum performance during vegetative growth and flowering

POWERMIX + POWERCALMAG = the ideal basic nutrition for autoflowering plants.

Application options

Mixing into the growing medium

Mix in evenly at a rate of 20–30 g per 11 litres of growing medium.

Top dressing

Spread 5–10 g over the surface of an 11-litre pot and water in afterwards.

When repotting

Work 10–20 g into every 11 litres of fresh growing medium.
