Plagron Hydro A&B 5L, universal fertilizer for hydro

Hydro A&B is a highly concentrated mineral-based basic plant nutrient for use during the plant's growth and flowering stages. This unique liquid fertilizer contains all trace elements in high quality chelated form (DTPA). This allows optimal growth, even if the pH value is not ideal or the soil temperature is too low. It can be used in all types of inert substrates.

Advantages of using Plagron Hydro A&B:

• Full control over nutrients and pH.
• Highly concentrated, economical to use.
• No crystallization of nutrients in the tank.

Instructions - dosage of Plagron Hydro A&B:

Shake well before use. Add a maximum of 1.6 ml of Hydro B per liter of water (1: 625). Use the same amount of Hydro A each time you apply Hydro B. Use this solution every time the plants are irrigated

Composition:

Hydro A: Water, calcium nitrate, magnesium nitrate and potassium chloride. NPK fertilizer (5-0-2). 5% Total nitrogen (N) of which 5% nitric nitrogen (NO3), 2% water-soluble potassium oxide (K2O), (CaO, 8.8%).Hydro B: EC FERTILISER.NPK fertilizers solution (2-5-9). 1.8% Total nitrogen (N) of which 1.8% nitric nitrogen (NO3), 4.8% water-soluble phosphorus pentoxide (P2O5), 8.7% water-soluble potassium oxide (K2O).

Available capacities:

Hydro A & Hydro B is available in a 1L bottle and 5L, 10L and 20L bottles.

Frequently Asked Questions (FAQ):

1. Can I use Hydro A & Hydro B on other hydrologic substrates, such as rockwool or mapito?

Plagron's Hydro A & Hydro B can be used on all types of hydrological substrates.

2. Your website states that Hydro A and Hydro B are effective over a wide pH range. Should I still adjust the pH value?

Yes. The pH value of the nutrient solution must be around 5.5. Chelates in the nutrient solution improve absorption when the pH value is deviated. However, since the pH value of your substrate may increasingly deviate from the pH value of the supplied nutrient water, it is still necessary to adjust the pH value of the nutrient solution.

3. My EC value becomes very high if I combine Hydro A and Hydro B with Green Sensation. How can I solve this?

Green Sensation increases the EC value by 0.55 uS / cm if you add 1 ml / liter. Solve this by adding Green Sensation first and then adding Hydro A and Hydro B until you reach the desired EC level.

4. How long does the nutrient solution stay fresh?

The nutrient solution can be kept fresh for four to ten days, depending on the hygiene of the grow room and water tank. Make sure that no organic products have been added to the solution, as they can begin to spoil after just 24 hours. It's best to monitor the pH value every day, as it will likely begin to slowly increase.
