Soil-grown plants are not suitable for hydroponic systems because they pollute the system. So the plants for hydroponic systems have to be grown from seeds or propagated through cuttings. For the cultivation of seeds, various substrates can be used.
The optimal supply of the root area with oxygen is very important in hydroponic cultivation. Growing media have the advantage that they are usually much more porous than soil and thus enable optimal oxygenation. The substrate must not dry out, so that the plants are supplied with nutrients.
We have performed tests using various organic and inorganic substrates, e.g. rock wool, plastic sponges, expanded clay balls, ceramics, perlite, coconut and with Eazy Plug®. Eazy Plug is a specially developed organic substrate that keeps the plant stable and does not decompose in the hydroponic system. It is compostable! The easiest way to grow plants was with Eazy Plugs, so we favor this substrate.
1. Select a substrate suitable for hydroponics, in which the seed can germinate and build roots. Eazy Plugs have worked well. Water the Eazy Plug and then place germinating seeds on it. Forr seeds which prefer a dark environmnt place the seed into the center of the plug and press into the substrate material.
2. Set the prepared Eazy Plugs in a seedling greenhouse. With the lid closed o create high humidity, wait for germination. The greenhouse should be placed in an area with light and at temperatures of approx. 22 °C. Keep moisture high and ventilate from time to time.
3. If the young plant is a few centimeters tall and the Eazy plug well rooted, it will be implemented in the hydroponic cultivation system. This can be done for better stability in mesh pots or in larger, rectangular Eazy plugs - the Eazy Block.
Many plants can be reproduced from healthy, strong mother plants via cuttings, such as basil. The process is simple.
1. Select strong, about 10 cm long shoots. Using a clean, sharp knife, cut off the shoot approx. 1 cm below a knot.
2. Remove the lower leaves and place the shoots in a glass of water. Best darken with aluminum foil and cover the glass - the humid environment has a favorable effect on the rooting of the cuttings. Let fresh air enter from time to time!
3. Once the cuttings have formed roots, they can be transformed to keep growing.
4. For aeroponics or NFT systems (Nutrient Film Technique) cuttings with good rooting are fixed in a slotted neoprene ring for stabilization and inserted directly into the hydroponics cultivation system.
5. For other hydroponic systems, the freshly cut cuttings can be placed directly into a wet Eazy Plug substrate and placed in an indoor propagator until they are well rooted through the substrate. Pay attention to high air humidity, always supply fresh air.
6. The well-rooted cuttings can also be converted directly into a network pot and stabilized with porous clay balls. The rooted Eazy plug is also used for better stabilization in a network pot.
Many different plants are suitable for hydroponic cultivation, including flowers and edible flowers. The size of the plants, whether hanging or standing, as well as the required light conditions, must be taken into account when growing the plants and selecting the hydroponic system.
In order to achieve good plant growth with high yield in hydroponic systems, favorable growth conditions are ensured. Since plants can absorb nutrients well only in a certain pH range, they the pH value of the nutrient solution is dajusted and checked regularly. The same applies to the nutrient supply.Suitable conditions should be set. For this purpose, simple measuring instruments are used, such as a EC meter for measuring the nutrient concentration via the electrical conductivity (EC) and a pH meter for measuring the pH value.
