Growth Technology Silica (Potassium silicate)

What is Growth Technology Silica and what is it used for?

It’s a potassium silicate additive that delivers plant-available silica to strengthen cell walls, reduce stress, and support healthier growth. It’s suitable for hydro, soil, coco, indoor plants, and even sensitive variegated types.

What are the benefits of using Growth Technology Silica?

Silica helps plants grow thicker stems, tougher leaves, and improves resilience against heat, drought, and pests. While it’s not a pesticide or cure-all, it enhances overall plant structure and reduces stress symptoms like browning.

How do I mix Growth Technology Silica with other nutrients?

Add it to plain water first, mix well, and let it sit for 10–15 minutes before adding other nutrients. Always follow with Cal-Mag or calcium products to avoid reactions or cloudy mixes.

What is the recommended dosage for Growth Technology Silica?

Use 5 mL per litre in hydroponics or 2–3 mL per litre for soil/potting mixes. Apply weekly or with every feed. One 1L bottle makes 200–500L depending on your system.

Should I use Growth Technology Silica during veg or flowering?

It’s commonly used from early veg into flowering. Some growers reduce or stop in late flower, but many run it consistently for structural support throughout the grow cycle.

Will Growth Technology Silica affect pH or EC?

Yes—it’s alkaline and can raise pH. Always measure and adjust pH after adding it. It also slightly raises EC, so test after mixing if you’re targeting specific nutrient levels.

Can Growth Technology Silica cause nutrient lockout?

It can indirectly if pH rises too far and affects uptake. Use a pH meter or test kit to monitor and keep your solution in the ideal range (typically 5.5–6.5 depending on grow style).

Why does my solution turn cloudy after adding Growth Technology Silica?

Cloudiness usually means a reaction—often from adding silica after calcium or other nutrients. Add Growth Technology Silica first, dilute well, and mix slowly to avoid precipitate or residue.

Is Growth Technology Silica safe to handle?

It’s alkaline, so avoid direct contact. Use gloves and eye protection when mixing frequently. If splashed in eyes or on skin, rinse with plenty of water and seek help if irritation persists.

How should I store Growth Technology Silica?

Keep it sealed, upright, and in a cool, dry place—away from direct sunlight or freezing temperatures. Always store out of reach of children and pets.

Can I use Growth Technology Silica with other nutrient brands?

Yes, but mixing order is critical. Add Growth Technology Silica to plain water first, stir well, then add nutrients one at a time. Avoid combining it with concentrates or premixed bottles.

Can I use Growth Technology Silica as a foliar spray?

It's possible, but not all setups suit foliar use. If trying it, dilute heavily, test on one leaf first, and never spray under intense light. Soil or hydro application is more common.

Can Growth Technology Silica clog drippers or irrigation lines?

If mixed poorly or combined with other products too quickly, it may cause buildup. Keep pH stable, avoid over-concentrating, and flush lines regularly in irrigation systems.
