What is Invasion OSA and how is it different from standard silica?
Invasion OSA is a highly bioavailable silicon additive that converts to monosilicic acid—the form plants absorb most efficiently. Unlike basic potassium silicate products, it’s designed for fast uptake, improved plant resilience, and stronger structure in both veg and bloom.
How do I activate and mix Invasion OSA correctly?
Always activate Invasion OSA by mixing it with fresh water first. Add this solution to your reservoir before any nutrients or additives. Never pour it directly into a nutrient tank. Shake well before use, and avoid mixing with other concentrates to prevent line clogging or pH drift.
What’s the recommended dosage for Invasion OSA?
For most plants, use 2 mL per 10 L of nutrient solution. Heavy-feeding strains may benefit from 3 mL per 10 L. For stretch control, 3–4 mL per 10 L is often used during week 2 of flower—only for one week, not continuously.
Can I use Invasion OSA as a foliar spray?
Yes. For general foliar use, apply at 1 mL per 1 L of water. For clones, reduce to 0.5 mL per 1 L. Foliar spraying is optional but helpful for quick support. Spray in early morning or just before lights off to avoid stress.
What grow systems and media are compatible with Invasion OSA?
Invasion OSA works in all systems—hydroponics, coco coir, soil, and recirculating setups. It’s safe for all plant types and can be used with any nutrient brand. Stacking with other silica products isn’t recommended unless you adjust for it.
Can Invasion OSA replace my base nutrients?
No. Invasion OSA is an additive, not a complete feed. It supports plant health and structure but still requires a full nutrient program to meet macro and micronutrient needs.
Will Invasion OSA affect pH or EC?
It can slightly shift pH or EC depending on your water and nutrient mix. Always activate and add Invasion OSA first, then nutrients, and adjust pH last. If you're running tight EC margins, measure rather than guess.
What happens if I use too much Invasion OSA?
Overuse can lead to nutrient uptake issues, pH instability, or visual stress in plants. If symptoms appear, reduce to baseline dose, simplify your feed, and stabilize EC and pH.
Will Invasion OSA improve yield or potency?
Invasion OSA can support larger leaf and flower growth, stronger stems, and better resilience—which helps plants reach their potential. However, yield and quality still rely on genetics, light, environment, and full nutrition.
Does Invasion OSA help with pests or mildew?
It can strengthen plant tissue, making it less vulnerable to pests and diseases like powdery mildew. However, it’s not a pesticide or fungicide—environmental control and hygiene are still essential.
How should I store Invasion OSA?
Store it sealed, upright, and in a cool, dark place. Avoid freezing or overheating. Shake well before each use to ensure even concentration.
Is Invasion OSA safe to handle?
Yes—treat it like any garden additive. Avoid eye contact, don’t ingest, wash hands after use, and keep it away from children and pets.
What sizes does Invasion OSA come in, and which should I buy?
Invasion OSA is available in sizes like 250 mL and up. For small home grows, the 250 mL size lasts a long time. Larger sizes are more economical for commercial or multi-reservoir setups.
