Opis

SI Star is an organically sourced silica powder designed to strengthen plants in all growth stages. It reinforces cell walls, ensures strong stems and branches, and increases resistance to drought, heat, pests, and diseases. The result is healthy, vigorous plants with improved development and higher yields.

SI Star can be mixed into the substrate during sowing or planting, or applied around existing plants and lightly worked into the soil.

Why Choose SI Star – Organic Silica

Strengthens plant structure

Silicon strengthens cell walls and improves the mechanical strength of plants. Stems and branches become firmer, more stable, and better able to support heavier fruits and abundant flowers.

Increases resistance to stress and diseases

SI Star helps plants better withstand heat, drought, pest attacks, and diseases. Thanks to strengthened cell structure, plants are less susceptible to damage and recover more quickly.

Improves overall vitality and growth

With the addition of silicon, plants use nutrients more efficiently, retain moisture better, and develop a stronger root system. This leads to healthy, vigorous, and balanced growth.

Easy application and rich mineral composition

SI Star can be mixed into the substrate during sowing or planting, or sprinkled around existing plants and lightly worked into the soil. In addition to silicon, it also contains iron, calcium, magnesium, phosphorus, copper, zinc, and manganese, further supporting healthy growth and overall plant vitality.

  • Mixing with substrate: Add 30–50 g of SI Star powder per 10 l of substrate (soil or coco) and mix well.
  • Top dressing on the soil surface: Apply 80–100 g of SI Star per m². Repeat once per month.
  • Watering: Add 5 g of SI Star per 1 l of water and water the plants. Repeat once per week for best results.
