Aptus Regulator — High-Concentration Silicic Acid

Aptus Regulator — High-Concentration Silicic Acid Plant Supplement

One of the most concentrated silicic acid formulations on the market, Aptus Regulator at 1:6666 dilution delivers usable silicon directly to the plant. Silicon builds stronger cell walls, boosts chlorophyll levels, and makes plants far more resistant to heat, water and salt stress — plus pests and disease. A quiet secret weapon in many top-tier grow rooms.

Why growers choose Aptus Regulator:

• 1:6666 dilution rate — super-concentrated, a small bottle lasts a long time, brilliant value per grow
• Boosts chlorophyll levels — more efficient photosynthesis, faster growth, deeper green foliage
• Improves resistance to stress — plants shrug off heat, water stress and salt spikes far better when silicon-fed
• Pest and disease resistance — stronger cell walls make plants harder for pests to damage and pathogens to invade
• Higher final yield and crop quality — the cumulative effect of stronger, healthier plants throughout the grow
• Aptus formulation — a trusted Dutch premium brand with a track record in pro and hobby grow rooms alike

Who it's not for:

Silicic acid is a supplement, not a base nutrient — you'll need a full feeding programme alongside it. Some growers find it conflicts with high-pH water (check your pH after adding). If you've never used a silicon supplement before, start with the smaller Aptus bottles to see how your plants respond before committing to a large size.
