Quick Answer

Plant Mechanics Super Si is a concentrated mono-silicic acid plant supplement for growers using soil, coco or hydroponic systems. Its specialised ultra-soluble silicic acid compounds and bioactive amino acids are formulated to support plant cell structure and resistance to abiotic and biotic stress. Add Super Si to clean reservoir water before any base nutrients or additives.

Product Description

Plant Mechanics Super Si supplies soluble silicic acid in a pH-stabilised formulation designed for use alongside an existing nutrient program. Plant Mechanics recommends Super Si during both vegetative and generative growth, with standard reservoir, early-bloom and optional foliar application rates.

The product is intended to support cell structure and formation, shorter internodal spacing and tighter flower sites. These are support functions rather than guaranteed outcomes; plant response depends on the crop, environment and complete growing program.

Directions for Use

  1. Fill the reservoir with clean water.
  2. Add Super Si first. For the standard reservoir application, measure 0.15 mL per litre of water.
  3. Mix or circulate the reservoir thoroughly.
  4. Add the base nutrients, followed by other additives in the feeding program.
  5. After all inputs are mixed, check the final solution and adjust pH to approximately 5.5–6.5 in line with the Plant Mechanics feed guide.

Early bloom: The manufacturer lists a double-strength rate of 0.3 mL/L for weeks 1 and 2 of the bloom cycle to help manage internodal stretching.

Optional foliar application: The manufacturer lists 1 mL/L. Follow the current bottle directions for foliar use.

Care and Maintenance

  • Use clean water and clean, accurate measuring equipment because the application rates are low.
  • Do not combine undiluted Super Si with concentrated base nutrients or additives; dilute and mix it in the reservoir first.
  • Account for the starting water EC/PPM when checking the final nutrient solution, as source-water values vary by region.
  • The Plant Mechanics feed guide recommends a nutrient-solution temperature of 18–21°C.
