Growing large, strong plants with a minimal risk of mould, disease or vermin? Go for hydro cultivation! Weed plants are suitable for growing completely without soil, just with the legs in the water. This creates strong, bizarre looking roots. But good weed nutrition is essential. That's why Plagron comes with Hydro A+B, a two-component nutrient with which you don't need anything else during the growth or flowering of your weed plant. Are you ready to try something new? Get off to a flying start in hydroponics with Hydro A+B. 1 litre per bottle and 1:400 mixing ratio. So you can get a long way with hydroponics! Read the detailed description for the benefits and an instruction for use.

Hydro Cultivation with Plagron Hydro A+B

Hydro A+B is a well-thought out and highly concentrated nutrition, especially for hydroponic cannabis plants. Hydroponic cultivation is done with this weed nutrition!

  • Suitable for both growing and flowering of the plant
  • Do not use Plagron Hydro A and Hydro B separately.
  • Together they provide a complete nutrition for healthy and strong marijuana plants
  • Full control over EC and pH value
  • Suitable for all inert substrates (clay granules, wool, etc)
  • The best plant food for hydroponic cultivation

What is Hydroponics?

Hydroponics is the cultivation of plants in such a way that they can stand with their roots in the water. Without soil. Although you could 'teach' every weed plant how to swim, it is important that you let them get used to it from an early age. We're not kidding: start hydro cultivation early so that they develop the roots that are suitable for only water. The roots of hydroponic plants look very different from plants that grow in the soil. This is because the roots of hydro plants develop in such a way that they can absorb enough oxygen. 

But what do you put your plant in? Good hydroponic soils include clay granules (hydro grains) and wool. They all offer an airy medium in which the roots can grow freely. Plagron Hydro A+B can be used in all inert soils. Coconut is less suitable because it is not completely inert. Still grow on coco? Choose Plagron Cocos A+B under "Others also viewed".

Why Hydroponics? The advantages:

  • Feeding is easier - Hydroponic nutrition dissolves in the water making it easy for the plant to absorb.
  • Most problems with marijuana plants arise from the soil and roots. Hydroponic plants are more resistant to mould, diseases and vermin.
  • Hydroponic plants can become huge, as long as the water balance is optimal. This increases the potential yield.
  • Full control of EC and pH values.
  • Nutrition is economically viable because Plagron A+B is highly concentrated.

Hydroponics also has disadvantages. In the beginning it takes some time to get used to the way and frequency of watering and feeding. These need to be closely monitored - the roots must never get dry.

Feeding Schedule Plagron Hydro A+B

Shake well before use. Add a maximum of 2.5 ml of Hydro A per 1 litre of water (1:400). Use the same amount of Hydro B with each dose of Hydro A, so a total maximum of 5 ml per 1 litre of water. Use this combined nutrient solution every time you water your plant.
