Differences between soil and hydroponics

As you know, indoors, people prefer to grow herbs and vegetables in soil or water-based hydroponics. If you decide to use hydroponics instead of regular soil, it is better to use a nutrient medium in the form of mineral wool or coconut coir.

Microgreens are harvested before fertilization.

Therefore, there is no need to use the soil. At the same time, you can be sure that there is no mess in the house. In the manufacture of mineral wool, basalt is used, which is first heated.

After it cools, it turns into compact fiber balls. They help retain moisture. If you prefer more classic growing radish microgreens indoors, you can fill trays or pots with regular soil. In this case, the use of different mixtures that are appropriate for you is allowed.

This should not be allowed because all microgreens deteriorate. For safety reasons and to prevent problems, it is better to take a larger container that fits a tray of greens.

It needs to be filled with water, and a tray with microgreens should be placed in it.

This allows water to gently flow into the tray, while the greens themselves not be affected by mold. The holes on the bottom ensure proper watering, simulating a smart system that prevents waterlogging.
