Super Si - Monosilicic Acid Concentrate

What is Super Si - Monosilicic Acid Concentrate?

Super Si is a highly concentrated, plant-available silicon additive made from stabilised monosilicic acid and amino acids. It supports stronger plant structure, stress resilience, and is suitable for use in hydroponics, soil, coco, and organic-style grows.

What does Super Si do for plants?

Super Si helps build stronger cell walls, leading to thicker stems, tighter internodes, and better stress tolerance. Many growers report sturdier growth, less leaf damage, and improved flower or fruit density when used consistently.

Can I use Super Si with other nutrients and additives?

Yes—Super Si is compatible with most nutrient lines, including Cal-Mag, PK boosters, enzymes, and microbes. Just follow proper mixing order to avoid cloudiness or reactions: Super Si always goes into water first.

What’s the correct way to mix Super Si into my feed?

Add Super Si to plain water first and mix thoroughly. Let it sit briefly, then add base nutrients and additives one at a time. Improper mixing—especially with calcium-heavy inputs—can cause cloudy solutions or precipitation.

How much Super Si should I use and how often?

For root zone: 0.15 mL per litre (15 mL per 100L). For foliar spray: 1 mL per litre of water. Use consistently throughout veg and flower, starting early. In soil, apply with your regular watering schedule.

Can I use Super Si as a foliar spray?

Yes—just spray during low light periods and avoid hot conditions. Most growers stop foliar use once flowers are forming. A wetting agent is optional but not usually required unless leaves heavily repel water.

Will Super Si affect pH or EC?

It may slightly raise pH or EC, but it's more stable than traditional silicate products. Always test and adjust pH after adding Super Si and nutrients. Softer water tends to produce cleaner results.

Is Super Si safe for irrigation and hydro systems?

Yes—when mixed correctly, Super Si is stable and suitable for recirculating systems and drippers. Avoid overdosing, maintain agitation, and clean lines periodically to prevent build-up over time.

Is Super Si safe around pets or kids?

Store securely, upright, and out of reach. While not toxic, it’s still a concentrated plant additive—rinse spills quickly and avoid skin or eye contact. Shake before each use for consistent dosing.

How long does a bottle of Super Si last?

At 0.15 mL per litre, each size goes far. For example, 100 mL treats ~667L, 500 mL ~3,300L, and 1L up to ~6,600L of solution—making it very cost-effective over time.

Should I switch to Super Si from another silica product?

If your current silica causes high pH, cloudy mixes, or doesn’t dissolve well, Super Si offers a cleaner, more bioavailable option. If your system is stable, a switch isn’t mandatory—but many growers upgrade for easier mixing and better results.
