Potassium Silicate Supplement | Silica Booster | Cell Wall Strengthener | Bloom Support | Indoor & Outdoor Growing | Hydroponics
Sturdy Stalk® is a premium potassium silicate supplement formulated to reinforce plant structure, increase cell wall rigidity, and enhance performance during the most demanding stages of the growth cycle. The bioavailable silica strengthens cell walls, helping plants support heavy yields, resist environmental stress, and achieve more vigorous flowering.
Stronger plant structure: thicker, reinforced cell walls.
Improved stress resistance: drought, high-intensity light and environmental challenges.
Enhanced blooming: provides potassium, essential for dense, high-quality flowers.
More available energy: plants spend less effort “building” structural tissues.
Better moisture retention and reduced dehydration risk.
0–0–1
Derived from potassium silicate + silica (SiO₂).
Use as needed, especially during stress periods, transition, transplanting, or mid-to-late bloom.
Combine with a high-quality bloom booster—Sturdy Stalk is not a replacement.
Add it last when mixing nutrients, then feed immediately due to its high reactivity.
Appearance: lemonade-like
Aroma: slightly caustic
Texture: watery
Shelf life: 10+ years
