What is a hydroponic fertilizer?

Generally speaking, it's a mineral fertilizer in liquid or water-soluble powder form. There are also organo-mineral fertilizers that are perfectly suited to hydroponic plant cultivation, as well as to certain types of cultivation. You can also adapt some organic fertilizers to your above-ground cultivation.

What is hydroponic fertilizer made of?

Hydroponic fertilizers are made up of 3 main elements: N (nitrogen), P (phosphorus) and K (potassium). Many of them include trace elements, i.e. all the micro-nutrients required for proper plant development. These trace elements include Calcium (Ca), Magnesium (Mg), Boron (B), Iron (F), Copper (Cu), Molybdenum (Mo), Nickel (Ni), all of which are necessary for the life of an organism.

How do I dose hydroponic fertilizer?

Simply look at the instructions on the back of each bottle of hydroponic fertilizer, and you'll also find all the tables and cultivation diagrams for the growth and flowering phases. Simply apply the number of ml/L and recalculate to suit your reservoir or tank of water and nutrient solution.

How does water-soluble powder hydroponic fertilizer work?

These are 100% water-soluble powder fertilizers, meaning that the crystals melt immediately in water to prepare your solution. These fertilizers are simple to use and easy to dose (on average 1g/litre of water, making them highly concentrated with 1kg = 1000 liters). Few fertilizers on the market are capable of such a high concentration in liquid form, apart from the technology of Platinium Nutrients with its Sensistar Grow and Bloom GEL fertilizer, which in our opinion is the best NPK + trace elements fertilizer, including Calcium and Magnesium.

When to use these products?

Hydroponic fertilizer brands have thought of you so as not to complicate your life, and offer you growth and bloom fertilizers as well as numerous additives such as root stimulators, enzymes, growth stimulators, bloom stimulators, PK bloom boosters, sugar activators, energy boosters, hydro-retainers, hydrogen peroxide, silicates, humic acid and fulvic acid. These additives and stimulators will help your plants to develop more effectively, resulting in healthier, more vigorous plants and more abundant harvests.

How to regulate the PH of hydroponic fertilizers?

You'll also find ranges of PH regulators with PH minus and PH plus to adjust your alkalinity and conductivity to feed your plants perfectly and avoid developing deficiencies due to poor nutrient absorption.

What PH and EC should I feed my plants?

In hydroponics, PH should be between 5.6 and 6.2 and conductivity (EC) between 0.8 and 2.2, depending on the stage of growth or flowering.

Here are all the fertilizers developed for use in hydroponics or aeroponics. Most of them are minerals that need to be fluid, perfectly soluble and 100% assimilable without residue.

Just like soil fertilizersfertilizers, hydro-aerosol fertilizers, used with the correct pHand ECas well as the right temperature to enable plants to assimilate them properly, and other components such as enzymes (catalysts)), provide optimum nutrition. Hydro-aerosol fertilizers will provide your plants with essential complements:
