OSA/28 Orthosilicic Acid, 1 Qt

OSA/28 Plant Available Silicon (as silicic acid) strengthens cell walls, increases nutrient uptake, and increases immune response. Other silicates are not bioavailable and take time+microbes to become available. This makes OSA/28 the fastest option for delivering silicon. Silicon also has a synergy with calcium. Many growers see increased calcium response when feeding with OSA/28. Silicic acid such as OSA 28 is very important for optimal plant health. Countless studies over the last couple decades from around the world show how silicic acid helps growers build stronger plants, optimize crop nutrition, plus increase yields and quality. OSA/28 Stabilized orthosilicic acid is a small group of silicic acid molecules suspended in solution. When added to water, these molecules break apart into monomer form -- this is how silicon becomes immediately and rapidly available to plants!

Faster Growth
Under fast growth conditions like indoor gardening, plants need constant resupply of essential elements. Every second nutrients are unavailable slows growth. Silicic acid works in many ways listed here to increase the transport and utilization of minerals, proteins and transports systems to ramp up growth.

Tighter Node Spacing
Countless studies show silicic acid affecting plant structure. It's one of the most visible and quickest effects growers report. Silicic acid builds more rigid and compact cells. It also helps convert more nitrates into proteins, which impacts node spacing and increases flowering sites.

Increased Nutrition
As silicon accumulates in cell walls, it concentrates and hardens. The nutrient transport system (xylem/phloem) is strengthened and expanded, increasing sap pressure and making heavier nutrients like calcium move better through the plant. More nutrients mean more essential building blocks.

Greater Yields
All plants accumulate silicon to some degree. Rice for example, up to 10% of dry weight! Flowering plants like tomatoes closer to 2-3%. Since silicon is twice as heavy as nitrogen and almost 3x carbon, a small amount of silicon contributes to large gains in yield.

Stress Resistance
Silicic acid is shown to establish powerful stress resistance factors when plants face tough conditions. It also helps with osmoregulation (water usage), making the plant more resistant to stresses like drought, heat, cold, and other environmental stresses. Lower Production CostsOSA/28 is up to 63% cheaper than other silicic acid products. Plant Science Concepts pioneered new manufacturing techniques and sourced clean American-made ingredients to cut costs. Aimed at empowering all growers.

Feeding and Application
-Root Feeding: 0.5 ML per gallon
-Always mix OSA/28 in clean water before other nutrients
-Allow to mix well to allow proper activation
-OSA/28 is compatible with any feeding recipe
-Your pH will drop after adding OSA/28 - add other ingredients and then adjust
-pH of final solution depends on your medium (typical range 5.7-6.3)
-Foliar Feeding: 4.0 ML per gallon
-Always mix OSA/28 in clean water before other nutrients
-Compatible with other foliar applied chemicals and nutrients
-Spray with lights off, just before day period
-OSA/28 doesn't need a surfactant but is compatible depending on application method
-Frequency: 2-3x Per Week
-For best results use OSA/28 every time you feed
-Start using OSA/28 as early as possible during growth - All vegetative weeks and through week 5/6 of bloom
-Double dose by root or foliar to reduce stretching in early bloom
