Patentkali® – Kalimagnesia with Potassium, Magnesium & Sulfur

Application and dosage of Kalimagnesia

Kalimagnesia is mixed in small amounts into the substrate or applied as a top dressing. Use only when there is a corresponding nutrient requirement.

Dosage at a glance

• Base mix and re-amending: 0.25–0.5 g per litre of substrate
• Top dressing: Lightly work in and water 0.25 g per litre of pot volume

How much you need

• 10 litre of substrate: 2.5–5 g
• 50 litre of substrate: 12.5–25 g
• 100 litre of substrate: 25–50 g

This is sufficient 500 g for approx. 1,000–2,000 litres and 1 kg for approx. 2,000–4,000 litres Substrate.

Step by step

1. Weigh the amount carefully – a precision scale helps with small quantities.
2. Mix evenly into the substrate or lightly work into the surface when top dressing.
3. Water in afterwards.
4. Observe the plants for a few weeks before adding more.

How quickly does Kalimagnesia work?

Potassium, magnesium and sulfur are present in water-soluble sulfate form and are therefore comparatively quickly available. This makes Kalimagnesia suitable for targeted supplementation – and overdosing must be strictly avoided.

Important notes

• Use only when there is a corresponding nutrient requirement.
• Do not combine uncontrollably with other potassium, magnesium or sulfur sources.
• Avoid overdosing.
• Official advisory recommendations take precedence.

Composition and analysis

CannaSelection Kalimagnesia is a concentrated mineral source of potassium, magnesium and sulphur.

Key figures

• Total potassium oxide (K₂O): 30 %
• Magnesium oxide (MgO): 10 %
• Sulfur trioxide (SO₃): 42.5 % (equivalent to 17 % sulphur)

What do these values mean?

30 % K₂O corresponds roughly to 25 % elemental potassium; 10 % MgO corresponds roughly to 6 % magnesium. The sulphur is present as sulphate: 42.5 % SO₃ corresponds to 17 % elemental sulphur.

Because all three nutrients are water-soluble in sulphate form, they are quickly available to plants. Therefore, it is best to apply sparingly and top up if needed.

The information corresponds to the labelling on the packaging. The information on the packaging is binding.

When is Kalimagnesia the right choice?

Kalimagnesia is suitable when …

• you want to specifically supplement potassium and magnesium during flowering,
• your Living Soil requires a concentrated potassium source in addition to organic sources,
• you want to cover potassium, magnesium and sulphur in one product.

Kalimagnesia is not suitable when …

• your soil is already well supplied with potassium and magnesium,
• you are already using several potassium- or magnesium-rich raw materials,
• you want to supplement nitrogen or phosphorus – other raw materials are more suitable then.

Kalimagnesia, Epsom salts, Kelp or Neem?

• Kalimagnesia (this product): Potassium, magnesium and sulphur, water-soluble in sulphate form.
• Epsom salts: Magnesium and sulphur without potassium – if only magnesium is missing.
• Kelp meal: plant-based potassium source (2.0 % K₂O) with organically bound nitrogen.
• Neem seed cake: organic NPK fertiliser 5+1+2.5 for basic nutrients.

Our tip: Use Kalimagnesia as a targeted supplement and combine it with active soil life, for example with MicroBio+. In top dressing during flowering, apply thinly and work in lightly.
