Description

Tougher stems that can carry heavier flowers

Plant Magic Silicon is a plant-strengthening additive that reinforces cell walls to improve structure, rigidity and resilience across soil, coco and hydroponic systems. By thickening and toughening plant tissue, silicon helps stems and leaves hold up heavy flowers through bloom while acting as a natural buffer against heat, drought and swinging humidity in the grow room. Used consistently through the cycle, it supports sturdier plants, better pest and disease tolerance and more efficient nutrient uptake.

Key Benefits

  • Stronger cell walls that reinforce stems and leaf structure
  • Heavier flower support, so stems resist bending or collapsing under bud weight
  • Improved stress tolerance against heat, drought and humidity swings
  • Better resilience to pest and disease pressure
  • Healthier vegetative growth and overall plant structure
  • Versatile across soil, coco and hydroponic setups

Worried about stems bending under heavy buds?

Weak plant structure leaves stems prone to bending or collapsing under heavy flowers and can throttle nutrient transport and overall performance. Plant Magic Silicon strengthens cell walls and plant rigidity so stems and leaves carry heavy flowering while shrugging off environmental stress, keeping plants upright and productive right through to harvest.

How to Use

  • Soil or coco: 1-2ml per litre of water.
  • Hydroponic systems: 0.5-1ml per litre of water.
  • When to use: throughout the vegetative and flowering stages, up to around two weeks before harvest.
  • Mixing order: add Plant Magic Silicon first and stir thoroughly before adding any other nutrients or additives.
  • pH last: adjust the pH of your solution last, as silicon can raise pH.

Medium Per 1 L Per 10 L
Soil or coco 1–2 ml 10–20 ml
Hydroponic systems 0.5–1 ml 5–10 ml
Note — Plant Magic's Ultimate chart ramps this from 1 ml/L for the first two applications to 2 ml/L for the following seven, which sits inside the soil and coco range above. Add Silicon FIRST and stir thoroughly before any other nutrient, and adjust pH last because silicon raises it. Stop about two weeks before harvest. Check pH and EC after mixing.
