Dutch Pro Silica 1L — Von Liebig's Silicon Supplement

Dutch Pro Silica 1L — Von Liebig's Silicon Plant Strengthener

A proper silicic acid supplement from Dutch Pro's premium range — uses silicon to strengthen stems, boost nutrient absorption, train plants to handle stress, and improve resistance against bacterial and fungal diseases. A foundational additive used by growers who treat plant health as the foundation of yield.

Why growers choose Dutch Pro Silica:

• Silicic acid formulation — bioavailable silicon that plants actually absorb, not just elemental silica
• Stronger stems and cell walls — supports heavy flowering plants, prevents stem breakage under bud weight
• Better nutrient absorption — silicon improves uptake of the other nutrients you're already feeding
• Stress resistance — plants handle heat, water stress, and environmental fluctuation better when silicon-fed
• Disease resistance — particularly useful against powdery mildew and common root zone fungi
• Promotes root development — healthier rooting leads to better overall plant performance

Who it's not for:

Silicic acid raises pH — check your solution pH after adding, adjust down as needed. Not a base nutrient; use alongside a full feeding programme. For similar benefits at more-concentrated dilution ratios, Aptus Regulator (1:6666) offers better value per litre. Best integrated with a full Dutch Pro feeding schedule for consistency.
