Growth Technology - GT Silica - Advanced Mineral Support
Growth Technology GT Silica is a precision-formulated mineral additive designed to deliver crucial structural and physiological support to fast-growing crops. By integrating highly bioavailable silicon into the plant's cellular matrix, GT Silica actively strengthens cell walls, creating a tough, physical barrier that significantly improves resilience against environmental stress, extreme temperatures, and mechanical damage. It is an essential component for high-performance gardens where heavy yields demand superior branch strength.
Beyond structural reinforcement, this premium mineral boost stimulates chlorophyll production to maximise photosynthetic efficiency and accelerate carbon dioxide (CO2) uptake. It is an indispensable supplement for growers looking to build sturdier stems, prevent canopy drooping, and cultivate highly resilient plants. By strengthening the plant's internal vascular system, GT Silica ensure a faster, more efficient flow of water and essential nutrients from the roots to the canopy.
Best For: Strengthening plant cell walls and stems, increasing resistance to physical stress, boosting photosynthetic rates and CO2 assimilation, and preventing drooping in heavy-fruiting varieties.
Key Features:
- Cellular Structural Reinforcement: Deposits silicon directly into cell walls to create rigid, woody stems and branches capable of supporting heavy flower and fruit loads.
- Enhanced Photosynthesis: Promotes robust chlorophyll production and optimises leaf positioning toward light sources, resulting in superior energy absorption.
- Superior Stress Tolerance: Buffers crops against physiological stress, helping plants transpire efficiently and thrive during periods of extreme heat, cold, or drought.
- Vascular System Optimisation: Strengthens the plant's internal transport pathways, facilitating a faster, more efficient flow of water and essential nutrients.
- Highly Stable Formulation: Engineered to mix cleanly into nutrient reservoirs, maintaining stability without falling out of solution when used as directed.
Specifications:
| Feature | Details |
|---|---|
| Brand | Growth Technology (GT) |
| Product Type | Liquid Silicon Additive / Mineral Supplement |
| Key Component | Soluble Potassium Silicate |
| Application Phase | Vegetative and Flowering Cycles |
| Compatible Media | Soil, Coco Coir, Rockwool, and Hydroponics |
| Available Sizes | 1 Litre and 5.5 Litre |
Ideal For:
- Stalk and Branch Strengthening: Apply throughout the vegetative and early bloom phases to prevent branches from bending or snapping under heavy flower weight.
- Environmental Buffer: Use as a continuous additive to safeguard indoor and outdoor gardens against summer heatwaves or fluctuating humidity levels.
- Hydroponic Reservoir Maintenance: Integrate into your primary nutrient recipe alongside base fertilisers to ensure a balanced mineral profile.
Usage Tip: Always add GT Silica to your water first and mix thoroughly before adding other nutrients. Silicon is highly alkaline and can cause nutrient lockout if it comes into direct contact with concentrated fertilisers in the reservoir.

Oversized Item Delivery Options
Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.
Available options include:
✔ Delivery to your closest depot for pickup - default method
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)
Important Notes:
- Shipping costs vary by location and method
- Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.
Business Delivery:
- Business delivery is available for commercial customers only
- If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
- If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
- Business delivery customers must provide a valid business address and contact information
- Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment
Let us know your preference, and we'll arrange the best solution for you!
Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
Biosecurity & Interstate Shipping Restrictions
Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
- Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
- Seeds cannot be shipped to Western Australia (WA).
Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
