What are hydroponic nutrients?

Hydroponic nutrients are specialised fertilisers created to give plants the necessary nutrients for growth, all without using soil. Hydroponic nutrients are usually dissolved in water and delivered directly to the plant’s roots, enabling quicker and more efficient nutrient uptake.

Benefits of using hydroponic nutrients

There are many benefits to using hydroponic nutrients, including:

  • Faster growth: Hydroponics nutrients can accelerate plant growth by up to 50% faster than traditional soil cultivation because the nutrients are provided directly to the plant’s roots in a readily usable form, which means that the plant can absorb them and use them immediately.
  • Higher yields: Hydroponic plants can yield up to 400% more than soil-grown plants. That is because hydroponic systems provide plants with optimal conditions for growth, including precise control over nutrient levels, pH, and temperature.
  • Better quality: Hydroponic plants often produce higher quality fruits and vegetables than soil-grown plants because hydroponic systems provide plants with a clean and sterile environment, which reduces the risk of pests, diseases, and contamination.
  • Improved plant nutrient: Hydroponic nutrient solutions make the plant easily absorb the nutrients just because the solutions which are modified to ensure the nutrients are bound to a molecule and get them to move without any hindrance throughout the plant’s cell wall.
  • Reduced water usage: Hydroponic systems use up to 90% less water than traditional agriculture. That is because hydroponic systems recirculate the nutrient solution, which helps to eliminate the need for evaporation and runoff.
  • Versatility: Hydroponic systems are versatile and suitable for cultivating huge plants, including fruits, vegetables, herbs, and flowers. They can thrive in different settings, including indoor spaces, outdoor areas, and greenhouses.

How do you choose the best hydroponic nutrients?

To choose the best hydroponic nutrients, consider the following factors:

  • Type of plants: Different plants have different nutrient requirements. For example, leafy greens like lettuce and spinach require more nitrogen, while flowering plants like tomatoes and peppers require more phosphorus and potassium.
  • Growth stage: Plants have different nutrient needs at various stages of growth. For example, seedlings and young plants need more nitrogen to promote vegetative growth, while flowering and fruiting plants need more phosphorus and potassium to support flower and fruit development.
  • pH: The pH of the hydroponic nutrient solution affects nutrient availability. Most plants prefer a pH of 5.5 to 6.5.
  • Nutrient concentration: Nutrient concentrations depend on the type of nutrient solution and the growth stage of the plants. It is vital to follow the manufacturer’s instructions to avoid over- or under-fertilising.

Here are some specific tips for choosing the best hydroponic nutrients for different types of plants:

  • Leafy greens: Leafy greens like lettuce, spinach, and kale require high levels of nitrogen and potassium. Look for a hydroponic nutrient solution with an NPK ratio of 20-10-10 or higher.
  • Fruiting vegetables: Fruiting vegetables like tomatoes, peppers, and cucumbers require high levels of phosphorus and potassium. Seek a nutrient solution with an NPK ratio of 10-20-10 or higher.
  • Flowering plants: Flowering plants like roses, lilies, and orchids require a balanced nutrient solution with moderate levels of nitrogen, phosphorus, and potassium. Look for a nutrient solution with an NPK ratio of 15-15-15.
  • Herbs: Herbs require different nutrient levels depending on the type of herb. For example, basil requires more nitrogen, while rosemary requires more phosphorus. Look for a nutrient solution designed specifically for the herbs you are cultivating.

It is also important to note that some plants may have specific nutrient requirements. For example, strawberries need ample calcium, whereas blueberries require a lot of iron. If you are growing a unique plant, examine its nutrient requirements and choose the best hydroponic nutrient solution UK that meets those needs.

Growing with an Organic Nutrient Solution

Organic hydroponic nutrient solutions originate from natural ingredients, such as plant and animal waste, compost, and seaweed extracts. Organic nutrients are more sustainable and environmentally friendly than synthetic nutrients, and they can help to improve the quality and taste of your plants.

When choosing an organic hydroponic nutrient solution, it’s important to make sure that it contains all of the essential macronutrients and micronutrients that your plants need to thrive. Some of the most popular organic hydroponic nutrient brands include BioBizz, Canna BioVega, and Plagron AlgaGro.

Growing Semi-Organically

Semi-organic hydroponic nutrient solutions are a mixture of organic and synthetic nutrients. This type of nutrient for hydroponics solution is a good option for growers who want to enjoy the benefits of organic nutrients without sacrificing the performance of synthetic nutrients.

The most prominent semi-organic hydroponic nutrient brands include Dutch Pro Hydroponics, Shogun Fertilisers, and House & Garden Hydroponics.

Growing Non-Organically

Non-organic hydroponic nutrient solutions originated from synthetic ingredients. Synthetic nutrients are typically more affordable than organic nutrients, and they can be very effective at promoting plant growth and yields.

However, it’s important to note that synthetic nutrients can also have negative environmental impacts. If you choose to use non-organic hydroponic nutrients, it’s compulsory to follow the manufacturer’s instructions carefully and safely to dispose of any unused nutrients properly.

What do plants need to thrive?

Plants need a variety of nutrients to thrive. The most significant nutrients are macronutrients, which include nitrogen, phosphorus, and potassium. Micronutrients, such as calcium, magnesium, and iron, are also essential for plant growth and development.

Hydroponic nutrient solutions typically contain all of the essential macronutrients and micronutrients in the correct proportions. However, it’s important to test your nutrient solution regularly to ensure that either they are still balanced or not.

Macronutrients & Micronutrients in Nutrient Solution


  • Nitrogen (N): Promotes plant growth and development
  • Phosphorus (P): Promotes root growth and flowering
  • Potassium (K): Promotes plant health and resistance to pests and diseases


  • Calcium (Ca): Promotes cell wall strength and nutrient uptake
  • Magnesium (Mg): Promotes chlorophyll production and photosynthesis
  • Iron (Fe): Promotes chlorophyll production and electron transport

How to Mix up Nutrient Solution

Simply adhere to the directions provided by the manufacturer to make a nutritional solution. Most nutrient solutions can be mixed with water at a ratio of 1:100. However, it’s vital to test your nutrient solution regularly to make sure that it is still balanced.

Powdered VS Liquid Nutrients

Powdered and liquid nutrients are both beneficial, but they have different advantages and disadvantages. Powdered nutrients are typically more affordable, but they can be more complex to mix and dissolve. Liquid nutrients are more expensive, but they are easier to mix and dissolve.

Tips for maintaining your Nutrient solution

  • Test your nutrient solution regularly to ensure it is still balanced.
  • Adjust the pH of your nutrient solution as needed.
  • Top off your nutrient solution regularly to avoid nutrient depletion.
  • Change your nutrient solution every 2-3 weeks to prevent the buildup of harmful salts and minerals.

Summer Growing

In the summer seasons, your plants will need increased water and nutrients because they are growing more quickly and using more energy. 

To accommodate the increased needs of your plants, you may need to increase the frequency of your fertigation schedule and the strength of your nutrient solution. However, it’s pivotal to avoid over-fertilising your plants since this might result in nutrient burn.

Winter Growing

In the winter seasons, your plants will need less water and nutrients because they are growing more slowly and using less energy.

To accommodate the reduced needs of your plants, you may need to decrease the frequency of your fertigation schedule and the strength of your nutrient solution. It’s also significant to ensure that your nutrient solution is at the correct temperature because plants cannot absorb nutrients efficiently when the mixture is too cold.
