Vulkastrat® 2-5

Vulkastrat is a pure mineral substrate made of pumice, zeolite and lava in grain fractions of 2-8 mm. Zeolites are natural ion exchangers, i.e. minerals that can absorb and release substances. Therefore, no organic substances are required when using zeolites. Due to their high exchange capacity, zeolites fulfil a similar function to humus and clay in natural soils. In addition to good nutrient storage, the mixedin high-quality zeolites ensure a stable pH

value and odorless water.

The benefits of Vulkastrat 2-5

• Substrate for houseplants
• Ideal for container plantings up to 50 cm pot diameter
• High water storage capacity of over 35% by volume
• Optimum air pore volume of over 25% by volume
• Weight approx. 950 kg per m³
• Permanent structural stability due to high grain strength
• Good water storage and optimum air pore volume at the same time
• Particularly suitable for water-storing systems
• Substrate is reusable
• Zeolites store nutrients that are released to the plant as required

Application of Vulkastrat 2-5

Vulkastrat has a good water storage capacity and a high nutrient storage capacity. The substrate is approx. 25% heavier than Vulkaponic and can also be used for indoor greening. Due to its higher weight, it provides plants with a less developed root system with special support in the substrate structure. Also suitable as a hydroponic substrate and for all water-storing systems. When repotting, please note: Remove any loose material from the plants, place them in Vulkastrat at the same height and water well.

Our substrates are always unfertilized; we recommend using our KLANZ Vulkapower Orange fertilizer once or twice a year.
