Product description

Advanced Hydroponics Silica – highly bioavailable silicon for stronger structure and better resilience

Advanced Hydroponics Silica is a premium additive from the well-known Dutch brand Advanced Hydroponics. It is based on silicon dioxide (SiO₂), also referred to as hydrolyzed silicon, and formulated for high bioavailability. This means plants can absorb and utilize it efficiently, supporting a sturdier structure and more consistent performance.

Why silicon matters

Silicon plays an important role in plant health. It can help strengthen cell walls and the plant’s outer protective layer, supporting natural resilience against stress factors. Silicon may also support the uptake of other nutrients, contributing to better energy management, more active root function and overall vigor.

Flexible and easy to use

Advanced Silica is versatile and can be used in the nutrient solution or as a foliar spray. Its practical application makes it suitable for both beginners and experienced growers and easy to integrate into most feeding programs.

Application and dosage

Use from the vegetative stage into flowering, typically up to around week 5/6 of bloom. Can be added to irrigation water or sprayed directly onto leaves. Recommended dosage: 0.1 ml per liter of nutrient solution.

Note: Adjust to your setup and schedule. For foliar use, apply as a fine mist and choose appropriate conditions.

Grow Island recommendation

Advanced Hydroponics Silica is a smart addition if you want stronger plant structure and more stability throughout the cycle, especially when building a solid foundation from early veg.
