Mills Vitalize — Bio-Silicon Plant Strengthener

Mills Vitalize — High-Absorption Bio-Silicon Plant Strengthener

Mills Vitalize is a premium silicic acid supplement in a revolutionary bio-silicon form — easier for plants to absorb than conventional silicon products. Silicon strengthens the plant's immune system, thickens cell walls, and increases harvest size and quality. Used throughout grow and bloom as a foundational supplement.

Why growers choose Mills Vitalize:

• Revolutionary bio-silicon form — more bioavailable than traditional potassium silicate formulations
• High concentration — small doses deliver significant silicon, good value per litre
• Strengthens the plant's immune system — better pest and disease resistance, less fungal vulnerability
• Thickens cell walls — stronger stems, thicker leaves, better support for heavy flowers
• Increases harvest size and quality — the cumulative effect of stronger, healthier plants
• Works in hydro, coco and soil — universal silicon supplementation

Who it's not for:

Silicic acid can raise pH — check your solution pH after adding Vitalize, adjust down if needed. Not a base nutrient; use alongside a complete feeding programme. For similar benefits at lower cost, Aptus Regulator offers pure silicic acid at a more concentrated ratio (1:6666). Best integrated with a full Mills feeding schedule for consistency.
