Cellmax Hydro Grow is a two-component fertilizer for the growth phase of your plants, especially for use on hydroponics. With Hydro Grow you give plants everything they need to grow healthy and strong. Nitrogen stimulates growth and ensures that the leaves get a beautiful green color.

Tap water contains many important elements such as calcium, magnesium, sulphate, phosphate and bicarbonate. Cellmax Hydro Grow is a specially developed fertilizer that uses these substances from the tap water, adjusts the EC of the water and contains all trace elements for growing plants in Hydroponics. Cellmax Hydro Grow will always give your plant the optimum nutritional content. Excess salt build-up (harmful to plants and the environment) is also prevented. Suitable for all common hydroponic systems.

X- en Y-components

Growing with a hydroponic system involves more than usual exposure to water, light and air. These factors influence the pH and Ec values of the water – and therefore also the nutrients dissolved in the water. Cellmax Hydro fertilizers take this into account by separating the products into an X and Y component. Only when you mix both components together do they become active. This way you get an optimal result.


Shake well before use. Prepare by diluting equal parts of the X and Y components with tap water in a ratio of 1:250. This is 4ml per litre. For best results, first dissolve one component in water and then the other. Do not mix components X and Y directly. When the components are mixed together in one go, this will lead to undissolved compounds. After preparation, use the mixture as soon as possible (within 24 hours).

We recommend an EC value of 2.0-2.5 (cf20-25) and a pH value between 5.5 and 6.2. Stir well before taking the measurements. If necessary, correct the pH value with Cellmax pH-Grow or Cellmax pH+.


Highly concentrated. Never mix the X and Y components undiluted, as this produces insoluble mixtures.

The concentrated product contains salts and acids that can irritate the skin, eyes, lips and throat.

Store in a dark place at room temperature.

NPK: 4-2-4. Contains chelates.


We are therefore transparent about how we make our products. You can read the complete composition of all products on the packaging. This way you know exactly what you are growing and what you are eating.

    As a vegetable lover, I am mainly engaged in the organic cultivation of my fruits and vegetables, but the engineer in me is always open to trying new things, such as hydroculture, which I heard so much about.

    First I started with a simple set of a Smart Herb Garden, but that was too limited for me. So I came to Cellmax’s hydro kit. The labels themselves can use some re-design, but wow those results! Honestly, I did not expect “these” results so quickly. My hot pepper on the hydro – which had fallen behind on the other pepper plants – grew much more explosively into a beautiful plant. In one month, the hydro pepper plant was twice as big as the rest and a little later, he was first full of masses of flowers. It was also the first plant with fruits and is even as delicious as the plants in soil and do not necessarily have to undergo taste, on the contrary.

    The different types of fertilizers are quite easy to use, but you have to get used to the two X + Y components. If you do not want to experiment, the grow schemes that Cellmax implies are good enough. In addition, they would like to provide additional advice, other schedules and tips especially for your situation.

    Caution, pH and EC meters are a must for the best results. For smaller amounts of fertilizer, use a syringe or pipette with a subdivision in ml. Maybe a tip for Cellmax to add that to their kit. My hydro experiments will certainly be continued next to my bio vegetable garden.
