Emerald Harvest Sturdy Stalk Potassium Silicate Silicon Additive 0.95L

Strengthen plant cell walls to support heavier harvests and crop resilience with our potassium silicate supplement.

Sturdy Stalk ensures your crops can support heavier harvests, better endure environmental stressors and resist other threats.

• Thicker and more rigid plant cell walls for studier plants
• Better stress resistance and overall crop hardiness
• More prolific budding, flowering and yields

• Sturdy Stalk’s key ingredient—silica—fortifies the internal structures plants need to support top-heavy plants laden with flowers and fruits.

  • Soluble silicon derived from potassium silicate
  • High (11.2%) silica (silicon dioxide or SO2) content
  • Additional bloom-boosting potassium
  • Thicker cell walls are harder to pierce and penetrate.
