Product Description

OSA?28 Plant Available Silicon (as monosilicic acid) strengthens cell walls, increases nutrient uptake, and helps plants handle all kinds of stresses. Other silicates are not bioavailable and take time+microbes to become plant available. This makes OSA?28 the fastest option for delivering silicon directly into the plant cell walls! Silicon also has a synergy with calcium in building better plant structure. Many growers see increased calcium response when feeding with OSA?28.

Usage rates
Root drench: Mix 0.5ml per gallon of water every feeding from early vegetative through mid-bloom.
Foliar spray: Mix 4-8ml per gallon of water 1-2 times per week.

Shelf Life
2 years when stored properly
Seal after use and store in a cool dark place.

Affordable! Higher concentration and lower MSRP than any true silicic acid product on the market.
