Two-componentfertilizer for the growth and flowering phase
Hydro A&B is a highly-concentrated organic mineral base fertilizer for use during the plant's growth and flowering phases. This unique liquid fertilizer contains a highly effective blend of trace elements in chelated form (DTPA). Hydro A&B ensures optimum plant development, even in the absence of an ideal pH value or when soil temperature is too low. The product can be used on all types of inert substrates.
Use
Shake well before use. Use a maximum of 1.6 ml of Hydro A for 1 liter of water (1:625). For each dosage of Hydro A, use the same dosage of Hydro B. Use this concentrated fertilizing solution with every watering.
Standard NF U 42-004 advises against the use of this fertilizer at less than 0.4 kg/m3 of water, and prohibits its use at more than 8. kg/m3 of water.
When correcting water used with mineral acids or alkalinizing products, use only products named and specified in the mandatory NF U 42-005: 1994 and NF U 42-006: 1994 standards.
Storage
Do not tilt the product during transport, and keep away from light. Recommended storage temperature: 10-35°C. Keep container tightly closed.

Tips from Plagron
Can I use Hydro A & B on other hydrological substrates such as mineral wool or mapito?
Hydro A & B from Plagron can be used on all regular hydrological substrates.
Your website states that Hydro A & B is effective over a wide pH range. Do I still need to adjust the pH value?
Yes, the pH of the nutrient solution should be between 5.5 and 6.0. The chelates in the nutrient solution improve absorption by deviating from these pH values. However, as the pH value of your substrate may deviate more from the pH value in the water of the nutrients you supply, adjusting the pH value of your nutrient solution is still necessary.
My EC value becomes very high if I combine Hydro A & B with Green Sensation. How can I solve this problem?
Green Sensation increases the CE value by 0.55 uS / cm if you add 1 ml / liter. Solve the problem by adding Green Sensation first, then adding Hydro A & B until you reach the desired CE level.
How long can I save my nutrient solution with Hydro A & B in the nutrient reservoir?
The nutrient solution can be stored for four to ten days, depending on the hygiene of the culture chamber and water tank. Make sure that none of the products have been mixed into the solution, as they may start to spoil after just 24 hours. Preferably monitor the pH value every day, as it will probably start to rise slowly.
