Plant Specific Gardening

The Focus Range by Growth Technology is a range of premium hydroponic nutrients designed to meet the needs of foliage plants, flowering plants, and other specialised crops. Backed by over 40 years of expertise, GT Focus brings professional nutrition solutions to passionate hobbyists.

For best results, use Focus nutrients at every watering. If you're not allowing runoff, be sure to flush your plants with plain water once a month to prevent mineral salts build up.

For optimal shelf life, store Focus nutrients in a cool, dark place. There’s no need to refrigerate them, unlike Clonex Gel, which benefits from colder storage.

Once mixed, a hydroponic nutrient solution will remain in optimal condition for about 1-2 weeks. After that, it can become a breeding ground for bacteria or fungi, which could harm your plants. To keep things fresh, replace the solution every couple of weeks, and give it a good oxygen boost by mixing it well before use.

Many new growers assume that hydroponics is complex, but you might already be using this method at home. If you’re growing plants in mediums like LECA, perlite, or sphagnum moss, you’re using hydroponic techniques without even knowing it. All you need are the right nutrients and additives to help your plants thrive.

For most hydroponic plants, a pH level between 5.5 and 6.5 is ideal. Regular pH monitoring is essential to ensure that plants can absorb nutrients efficiently and maintain growth.

Yes, all our products are 100% vegan, containing no animal-derived ingredients or byproducts, making them an excellent choice for eco-conscious growers.

Yes, tap water is often the best choice for hydroponic systems. It has natural buffering capacity that helps stabilise the pH of your solution, unlike distilled or reverse osmosis water, which can cause pH fluctuations that could affect your plants’ nutrient uptake.

To get the most out of GT Silica, it can be used with every watering. Regular use will help your plants develop sturdy cell walls, making plants them better equipped to handle environmental stress and grow stronger over time. For optimal results, incorporate GT Silica consistently into your feeding schedule throughout the plant's lifecycle.

Yes, Rootzone is an organic-based supplement designed to be used alongside GT nutrients throughout your plant’s entire life cycle.

GT Silica is a potent additive that helps strengthens your plants’ cell walls, helping them become more resistant to environmental stressors like heat, drought, and pests. Though not considered an essential nutrient, Silica is extremely valuable for improving overall plant health. In addition to structural benefits, Silica also supports better nutrient absorption and increases resilience to physical stress, helping your plants grow stronger, healthier, and more vibrant. It also helps maintain variegation in plants, preventing the development of brown spots and improving the overall appearance of your crops.

Rootzone is an organic-based supplement designed to maintain optimal root health throughout your plant’s entire lifecycle. Healthy roots are the foundation for a thriving plant, so ensuring they’re in top condition is key to maximizing overall plant growth and yield. Rootzone helps improve nutrient uptake, boost root vitality, and create the ideal environment for your plant’s roots to flourish. Although Rootzone is not specifically formulated for cloning, it provides long-term benefits for plants from seedling to harvest, ensuring healthy and thriving roots at every growth stage. Rootzone is essential for boosting the foundational strength of your plants, making it a must-have additive for any hydroponic system.

CCS and Rootzone each play a unique role in plant growth. CCS is a specially formulated nutrient solution that provides cuttings and seedlings with essential nutrients for strong root development and healthy early growth, giving young plants the best start possible. Rootzone, an organic-based supplement, supports plants throughout their entire life cycle by enhancing nutrient uptake and promoting optimal root health. It ensures plants continue to thrive as they mature. Together, CCS and Rootzone form a seamless nutrient system – CCS gives seedlings a strong foundation, while Rootzone offers long-term support – ensuring your plants grow healthy and productive from first sprout to final harvest. Whether you're new to hydroponics or a seasoned grower, these two products working together ensure your hydroponic garden flourishes at every stage.

While GT Silica provides many advantages on its own, we recommend using it in combination with a balanced hydroponic nutrient program. Silica is most effective when paired with the 12 essential nutrients that your plants need to thrive. Simply follow the instructions on the label to ensure you're using it properly alongside your regular nutrients.

Nutrients and additives both play important roles in plant care, but they serve different purposes. Nutrients provide the essential 12 minerals that plants need to grow strong and healthy, offering a complete and balanced nutrition profile. On the other hand, additives are designed to give your plants that extra boost during specific stages of growth. Think of them as supplements – while nutrients provide the core building blocks, additives enhance particular plant processes, such as strengthening roots, promoting flowering, or improving resilience. Additives serve as supplements to your base nutrient solution. They enhance specific plant processes like root development, flowering, and stress resistance. Products like GT Silica, Rootzone, and Super PK help boost plant growth during critical stages.

Additives like GT Silica, Rootzone, and Super PK are specifically formulated to complement our nutrient range. They support plant health at various stages of growth. GT Silica helps fortify cell walls, making plants stronger and improve stress resistance. Rootzone promotes health root development and better nutrient uptake, giving your plants the foundation they need to thrive. Super PK supports strong flowering and bud development during the flowering stage. When used in combination with our core nutrients, additives can take your plant’s growth to the next level, ensuring that every phase of its life cycle is as healthy and productive as possible.
