What is Hydroponics?

Hydroponics is an innovative and sustainable way to grow plants without soil. Instead, plants are nurtured in a nutrient-rich water solution, which delivers essential nutrients directly to their roots. These roots are typically supported by inert mediums such as Coco Fibre, LECA, perlite, or peat moss. A common misconception is that hydroponics means growing plants solely in water or under artificial lighting – while these elements can be part of the system, the core of hydroponics is the soilless delivery of nutrients.

Could you be growing hydroponically without realising it?

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.

Why are hydroponic nutrients crucial for plant health?

Without soil, your plants rely entirely on you to provide the nutrients they need. Hydroponic nutrients are critical for maintaining plant health, ensuring efficient nutrient absorption, and promoting optimal growth. By using a nutrient solution, you’re giving your plants exactly what they need to flourish – all in the right amounts.

Why do micronutrients matter in hydroponics?

Micronutrients are needed in smaller amounts but play a crucial role in plant health. Micronutrients like Iron (Fe), Manganese (Mn), Zinc (Zn), and Copper (Cu) assist in everything from enzyme activation to chlorophyll formation. While needed in small amounts, these nutrients are vital to your plant’s health and growth.

How do I mix hydroponic nutrients effectively?

For precise nutrient mixing, follow the product’s guide and measure carefully. Using accurate tools helps ensure proper nutrient dilution and maintains correct pH levels for optimal plant absorption. This ensures your plants get the most out of every drop.

What’s the ideal pH for hydroponic nutrient solutions?

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.

How can I spot nutrient deficiencies in hydroponics?

Nutrient deficiencies show up in the form of yellowing leaves, poor root growth, or browning leaf edges. Monitoring your plants for these symptoms can help you make quick adjustments to your nutrient solution and ensure healthy, productive growth.

How long does mixed hydroponic solution last?

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.

Are GT products vegan-friendly?

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

Can I use Tap Water for My Nutrient Solution?

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.

What is the difference between Clonex Clone Solution (CCS) and Rootzone?

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.

How often should I use GT Silica?

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.

Do I need to use a nutrient with Rootzone?

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

What is GT Silica and how does it benefit my plants?

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.

What is Rootzone and why should I use it?

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.

Can I use GT Silica on its own?

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.

What is the difference between nutrients and additives?

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.

How can additives help my plants thrive?

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.
