#hydroponic nutrients

Hydroponics allows plants to grow faster and healthier by delivering nutrients directly to their roots through water. But success depends on one thing — the right hydroponic nutrient solution. A well-balanced nutrient feed ensures your plants receive everything they need for strong roots, thick stems, vibrant leaves, and abundant yield — all without soil.

If you’re looking for professional results at home, the CompleteGrow Hydroponic Nutrients A & B Formula is one of Australia’s most trusted systems for clean, consistent feeding. (See product here: https://completegrow.com.au/product/hydroponic-nutrients-fertilizer-two-part-formula-a-b/)

Why Hydroponic Nutrients Matter

In hydroponics, water does all the work — meaning your plants rely 100% on what’s dissolved in it. That’s why you need a balanced mix of macronutrients and micronutrients, in precise ratios. The CompleteGrow two-part formula provides a complete solution:

Part A: Supplies calcium-nitrate, potassium‐nitrate, trace elements for cell strength.

Part B: Adds magnesium, phosphate and additional potassium for photosynthesis and flowering.

Its NPK ratio is about 25-6-40, delivering strong vegetative growth and vibrant fruiting — perfect for leafy greens, herbs, and fruiting vegetables.

How to Mix Hydroponic Nutrients

Fill your tank or container halfway with clean water.

Add Part A at recommended dosage (e.g., 3 mL per L), stir.

Add Part B next, stir again.

Never mix the concentrates together undiluted.

Feed plants every 7-10 days or continuously depending on your system. Monitoring pH and EC is key for hydro setups.

Choosing the Best Hydroponic Nutrients for Your Plants

The right nutrient solution depends on your crop type and setup:

Leafy greens & herbs: Use balanced base like CompleteGrow A & B.

Tomatoes & peppers (fruiting): Combine base with calcium/magnesium supplement.

Flowering plants: Use base formula then feed higher P/K during bloom phase.

All formulas from CompleteGrow are 100% water-soluble, Australian-made and compatible with NFT, DWC, flood-and-drain and coco systems. CompleteGrow+1

FAQs About Hydroponic Nutrients

What is hydroponic nutrient solution used for? It delivers all essential nutrients to plants growing without soil — ideal for hydro systems.

How often should I feed hydroponic plants? Typically every watering or reservoir change, depending on system design.

Can I use regular fertiliser in hydroponics? Not safely — soil fertilisers may contain slow-release elements or insoluble particles that clog hydro systems. The guide explains this clearly. CompleteGrow

What pH should I aim for in hydro? Generally between 5.5 and 6.5 for optimal uptake. The guide covers nutrient interaction and this setting.

Final Thoughts

In the world of modern agriculture, hydroponic gardening has emerged as a revolutionary method of cultivating plants without soil, using nutrient-rich water solutions. This innovative approach offers numerous advantages, including efficient resource utilization, faster growth rates, and the ability to grow crops in environments where traditional farming may not be feasible. Among the myriad of plants that can thrive in hydroponic systems, some stand out for their adaptability and productivity.

Leafy Greens: Lettuce, spinach, kale, and other leafy greens are some of the most popular choices for hydroponic cultivation. They have shallow root systems and high water requirements, making them perfectly suited for nutrient-rich water environments. With the right hydroponic setup, these greens can be grown year-round, providing a consistent supply of fresh produce.

Herbs: Basil, cilantro, mint, and parsley are excellent candidates for hydroponic growth. These aromatic herbs flourish in controlled hydroponic environments, offering superior flavor and quality compared to their soil-grown counterparts. Hydroponic herb gardens are ideal for culinary enthusiasts seeking a convenient and sustainable source of fresh herbs.

Tomatoes: Tomatoes are another popular choice for hydroponic cultivation. They thrive in nutrient-rich solutions and benefit from the support of trellises or vertical systems. Hydroponically grown tomatoes often exhibit enhanced flavor and texture, making them a favorite among home gardeners and commercial growers alike.

Cucumbers: Cucumbers are well-suited for best hydroponic systems, particularly when grown vertically to maximize space efficiency. With proper support structures and nutrient delivery, hydroponic cucumbers can produce abundant yields of crisp, flavorful fruits throughout the growing season.

Peppers: Bell peppers, chili peppers, and other varieties can thrive in hydroponic environments. These plants require consistent moisture and nutrient levels, which can be easily maintained in hydroponic systems. With proper care, hydroponically grown peppers can yield bountiful harvests of vibrant, flavorful fruits.

Strawberries: Hydroponic strawberry production has gained popularity in recent years due to its ability to maximize space and optimize growing conditions. By utilizing vertical towers or hanging systems, growers can cultivate strawberries without soil, leading to cleaner, healthier fruits and increased yields.

Microgreens: Microgreens are young, tender greens harvested at an early stage of growth. They are packed with nutrients and flavor, making them a popular choice for salads, sandwiches, and garnishes. Hydroponic systems offer an efficient means of producing high-quality microgreens year-round, providing chefs and home cooks with a continuous supply of fresh, nutritious greens.

Potatoes: While traditionally grown in soil, potatoes can also be cultivated hydroponically, especially in potato vertical farming systems. With proper tuber support and nutrient delivery, hydroponic potatoes can yield impressive harvests in a fraction of the space required for conventional soil cultivation. Vertical farming techniques optimize space utilization, making them ideal for urban agriculture and limited land environments.

When it comes to choosing the best hydroponics system for growing these plants, several factors should be considered, including available space, budget, and desired crop varieties. Vertical farming systems, such as tower gardens or vertical hydroponic racks, offer an efficient solution for maximizing space and increasing yields. These systems allow growers to stack multiple layers of plants vertically, optimizing space utilization and productivity.

The Calcium Nitrate Market size continues to increase sharply as the U.S. agricultural sector prioritizes high-yield, nutrient-efficient crop production. With 2.58 million tons consumed in 2024 and demand expected to reach 4.25 million tons by 2032, calcium nitrate is emerging as a key nutrient source supporting modern farming practices.
