Hesilicio
More Than Just a Booster
Plants need more than just water and nutrients – they need power to withstand everyday challenges. Whether drought, pests, or fluctuating temperatures. That is why we are proud to add a brand new product to our range: Hesilicio. This new booster contains silicon and has been specially developed to strengthen the health and resilience of your plants.
What is Hesilicio?
Silicon is an essential element that plays a key role in the strength, growth, and resilience of plants. However, plants cannot absorb pure silicon in its raw form as it is solid. It must first be available as orthosilicic acid – a soluble form of silicon.
Hesilicio contains 3% orthosilicic acid in a colloidal form, making it easy for plants to take up through both roots and leaves. This highly effective booster supports stronger cell walls, improved nutrient absorption, and increased resistance against stress, pests, and diseases.
Highlights:
🧱 Stronger cell walls in leaves and roots
🛡️ Increases resistance to drought and infections
💪 Improves nutrient uptake
💧 0,5 ml per 1 liter of water
👉 Less is okay – but do not exceed this amount. Rather apply more often.
Add to irrigation water every 2–4 weeks, adjusting to the concentration and the plant’s needs.
Apply either through watering or as a foliar spray.
Compatible with all Hesi fertilizers and boosters.
- 3% orthosilicic acid (SiO₂ / SiO₃) in colloidal form – the silicon particles are stably dispersed in the liquid and can be absorbed especially effectively through roots and leaves.
Hesilicio is available in the following sizes:
- 50 ml
- 100 ml
- 250 ml
- 500 ml
- 1000 ml
- 2500 ml
DID YOU KNOW?
In nature, silicon is found in sand and rocks, but in a form that plants can hardly absorb. Through the slow weathering of these minerals, small amounts are released as orthosilicic acid – the only form of silicon plants can actually take up.
