Hesi Hesilicio – a powerful silicon booster that strengthens plant structure, increases stress resistance and enhances nutrient uptake for healthier, stronger, high-performing crops.
Hesi Hesilicio is a concentrated silicon booster based on stable orthosilicic acid (3%), designed to strengthen plants at every stage of growth. Silicon reinforces cell wall structure, improves the rigidity of leaves and stems, and increases resistance to stress factors such as temperature fluctuations, high light intensity, humidity, and pathogen pressure. As a result, plants grow healthier, become more stable, and make better use of supplied nutrients.
Hesilicio works both in the aerial parts of the plant and within the root system. It improves water transport, supports nutrient uptake, and boosts the plant’s natural resilience. It performs effectively in soil, coco, and hydroponic systems, making it a convenient and efficient addition to any standard feeding program.
Key benefits of using Hesi Hesilicio:• strengthens cell walls and increases overall plant durability
• improves resistance to heat stress, drought, disease, and strong LED/HPS lighting
• stabilizes stems, reducing breakage during the flowering phase
• supports root development and enhances nutrient absorption
• works in all growing media and mixes easily with any fertilizer line
Benefits for your grow
Plants handle difficult conditions more easily and recover faster from stress, while stronger stems ensure stability during flowering when bud weight is highest. Improved water management makes plants less prone to wilting, and enhanced resistance to disease and environmental stress leads to a more reliable and healthier harvest. Hesilicio is a simple and effective way to improve crop condition without needing major changes to your nutrient schedule.
How to dose Hesi Hesilicio?
Use 0.5 ml per 1 liter of water, typically once a week depending on plant needs. It can be applied both as a watering solution and as a foliar spray. Shake well before use, and always add the concentrate to water — never the other way around.
Hesi Hesilicio is suitable for use in any growing medium.
