🌿 SUPER SI – 100% Mono-Silicic Acid

The Ultimate Silicon Booster for Stronger, Healthier Plants

SuperSi is the latest breakthrough in hydroponic and soil nutrient tech! This powerful formula combines ultra-soluble nano-particulate silicic acid with bioactive amino acids to supercharge your plants’ vegetative growth and flowering performance.

It delivers the highest concentration of mono-silicic acid available today, using a specialised blending technique that boosts silicate absorption without affecting your pH.

⚡ Why Use SUPER SI?

💪 Builds stronger stems, leaves, and cell structure for more robust plants
🛡️ Enhances natural pest & disease resistance
🌿 Shortens internodal spacing for tighter flower clusters
❄️ Improves tolerance to heat, cold, and other environmental stressors
🌸 Significantly increases fruit and flower size & dry weight
🌱 Pure, organic silicon boost with no synthetic PGRs or harmful chemicals

💧 How to Use SUPER SI?

For Soil, Coco & Hydroponics:

Add 15ml per 100L of water BEFORE any other nutrients or additives, then mix well.
For foliar application, spray at 1ml per 1L for rapid uptake through leaves and accelerated cell strengthening.

🧠 Grow Guys Tip:

Use SuperSi throughout both vegetative and flowering cycles for maximum crop resilience and yield boosts. It stabilises pH and integrates perfectly with any nutrient program!

Stronger plants, bigger yields — powered by SuperSi.

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
