Hydro A&B


Hydro A+B is a fast-acting basic feed and contains all the necessary nutrients for the plant during the growth and flowering phase. The nitrogen compounds and trace elements in Hydro A+B are rapidly absorbed, allowing you to grow powerful plants with a well-developed root system.Hydro A+B has been specially developed for use in open hydroponics cultivation systems with nutrient-poor substrates such as rock wool. 

Active substance NPK fertilizer, main and trace elements. Hydro A+B dissolves immediately and is very suitable for drip and irrigation systems. Ensure that the components Hydro A and Hydro B do not come into contact with each other and are added to the irrigation water separately.

Hydro A+B is a regular basic feed that is used during the growth and flowering phase. Hydro A+B is especially recommended for nutrient-poor substrates.

Hydro A is used in combination with Hydro B. Add the same amount of both to the irrigation water. Stir well and let the solution stand for a few hours.

Note! The concentrates must never be mixed directly with each other! The concentrates consist of acids and can irritate the skin and mucous membranes. Therefore, avoid any body contact. Always check the pH. PH- or PH+ can be used to correct the pH. When used on fertilized (potting) soil, halve the dosage.

Use 1 ml to 4 ml Hydro A and 1 ml to 4 ml Hydro B per 1 litre of irrigation water. Adjust the dosage to the target EC value (1.2 – 2.5), depending on the stage of growth of the plant. The desired pH value is (5.5 – 6.0). When growing on (potting) soil, the desired pH value is (6.0 – 6.3).

Keep out of reach of children. Store in a cool and dark place. Minimum storage temperature 5°C.

Usage Instructions: Wear suitable protective clothing, gloves and eye protection. Rinse immediately with plenty of water. If swallowed, seek medical advice immediately and show the label. Do not eat, drink or smoke during usage. Keep away from children. N-NO3.

Narcos Hydro A+B is an EC Fertilizer and contains primary, secondary and micronutrients.
