MACRO ELEMENTS AND MICRO ELEMENTS IN HYDROPONICS

For optimal plant growing in hydroponics need about 16 minerals. Not all minerals have the same importance for the plant. The three major minerals that plants use large quantities of are:

Nitrogen (N) - Phosphorus (P) - Potassium (K).
The amount of NPK are almost always listed on the labels of fertilizers, for example "21-15-21".
These numbers correspond to the percentage of weight of each macro element, better known as N, P and K.
The macro elements that are present in indoor growing plants when combined with each other and with the micro elements determine the state of health of plants.
Generally also Sulphur (S), Calcium (Ca) and Magnesium (Mg) are considered macro elements.

The combinations of nutrients play a crucial role in plant health:

Nitrogen (N): promotes the development of new leaves.
Lack of nitrogen can be seen with clear leaves and faded.

Phosphorus (P): promotes the development of roots and the flowering stage.
The shortage is manifested with dark leaves, red and purple and slow growth.

Potassium (K): important to protect the plant from problems and determining growth in situations of extreme temperatures.
Lack of manifest with dry leaves and yellow from the end.

Sulphur (S): helping to maintain healthy plants.
Responsible for green / black leaves.

Calcium (Ca): promotes the development of roots and new shoots.

Magnesium (Mg): promotes the synthesis chlorophyll, the pigment that gives colour to the leaves and absorbs the green light to turn it into Mg ions.
Lack of Magnesium is manifested by yellow leaves with green veins.

Boron, copper, cobalt, iron, manganese, zinc, etc. There are plants in small quantities and are known as micro-nutrients. The plants absorb the proper amount of micro-nutrients from the soil.
This is why many fertilizers grow equipment on the ground do not contain trace. In hydroponics, when we’re not using soil, fertilizers are rich in specific micro elements.

HYDROPONICS YAROOTS DWC SYSTEM (Deep Water Culture)

DWC SYSTEM (Deep Water Culture)

The YAROOTS HYDROPONIC DWC system (Deep Water Culture) is one of the most easy methods of hydroponic growing as it allows plants to grow and suspend with the roots immersed in the nutrient solution.
The solution is super oxygenised from an air pump combined with porous stones. With this method the plants grow much faster because of the high amount of oxygen that the roots receive.

The YAROOTS HYDROPONIC DWC system requires adequate water + oxygen nourishing solution.
It is advisable to start this type of indoor cultivation with cubes of rock wool. Visit the section ‘GERMINATE IN ROCK WOOL CUBES’. Once the seeds are germinated in cubes of rock wool, put them into the DWC baskets previously filled with clay expander. Fill the hydroponic DWC system with water and fertilizers that are hydroponic specific up to the level of the solution in contact with the base of baskets.

In this way, the clay will be in contact with the solution that will be absorbed by the plants roots. Soon the plant will develop a large root system that will naturally immerse in the nutrient solution. It will not be necessary to maintain the level of nutrient solution to the same level of the base of the baskets, but results will come with a lower level. It is recommended replacing the nutrient solution approximately once a week and wash the container / tank with hot water to remove any algae, mould and salt deposits. Every time you fill the tank, measure the pH of the solution and ensure that its value is between 5.5 and 6.8. Revise with the pH indicator. Constantly monitor the pH. The well-oxygenated and enlightened environment promotes the development of algae. It is therefore necessary to wrap the tank with black film obscuring all light.

It is also recommended the use of Super liquid enzymes for a complete nutritional diet (Hereinafter the table with dosages).

STRENGTHS

Growth Stage:
Dilute 50ml of CELLMAX HYDRO GROW component X 20 litres of water.
Dilute 50ml of CELLMAX HYDRO GROW component Y 20 litres of water.
Fill the tank with 40 litres of solution previously diluted.
Add 20 ml each Super enzyme replacement of water.
Flowering Phase:

Dilute 50ml of CELLMAX HYDRO BLOOM component X 20 litres water.
Dilute 50ml of CELLMAX HYDRO BLOOM component Y 20 litres water.
Fill the tank with 40 litres of solution previously diluted.
Add 20 ml each Super enzyme replacement of water.

How to eliminate the formation of algae in the system?

The best approach is prevention. To prevent algae, obscure the system with some black film to avoid light entering. If algae does occur, use boiling water and hydrogen peroxide (3 ml every 4 Lt) and scrap with a algae brush.
