What is Meant by Seeds Germination?

The germination of seeds (or sprouting of seeds) is essential in the life cycle of a plant. At this stage, under favorable environmental conditions, the embryos in the semen begin to come out of dormancy. All parts of the plant develop, from roots to stems, branches and leaves, thanks to the substances of the metabolic process of the seeds and the nutrients in the soil. The indoor germination techniques involve the germination of seeds in hydroponic containers or structures composed of materials such as rock wool, coconut or peat.

Ideal Temperature and Humidity for Germinating Seeds

Before we dive into germination methods, here are some golden rules for proper seed germination. For best results, we recommend that you follow these guidelines closely, regardless of the germination technique you choose. Of all the factors to consider, temperature is the most important factor. The seeds are always looking for the minimum moisture, but they use the temperature to know when to germinate.

  • The ideal temperature is between 22° and 25°C;
  • The cultivation environment should be humid, but not wet;
  • The ideal relative humidity range is between 70% and 90%;
  • Seeds prefer led lights;
  • Try to handle the seed as little as possible;
  • In hydroponic/rock wool growth, the ideal pH is between 5.8 and 6.2.

Environmental Factors for Germinating Seeds

The environmental factors that allow the development of the first taproot are: heat, humidity and darkness. In the constant search for moisture, the roots will slowly develop into the beautiful plant we all love. Under optimal conditions, seeds begin to develop within 12-36 hours of adding moisture to the environment. Times may vary. It all depends on the environment in which the seeds germinate. Even the bulkier grower can sprout a seed, but it can take a few weeks, risking a weak plant.

Seed Germination Methods

There are numerous methods to germinate seeds, some more effective than others; these listed below are the indoor germination methods our team of professionals Eureka Grow Shop prefer and recommend to all growers, from beginners to professional growers.

Glass of Water Method

This is one of the least efficient, but still valid methods. This is a very simple technique often used by novice growers. A glass should be half filled with water at a temperature of about 22°C. After 3–5 days the seed will begin to develop and the first thin white roots should appear. When they reach 2–3 mm in length, carefully remove them from the water and transfer them to a pot filled with soil. Dig small holes in the ground and place the shoots inside. After placing the seeds, install a led light 13-15 cm away to encourage the growth of the seedlings. We recommend that you avoid giving excess water to newly developed seeds. Use a nebulizer to create a humid but not excessively wet environment.

Wet Paper Napkin Method

This is probably the most used method. The wet napkin method has many variations. Some growers use cotton balls or paper. In this guide we will use a paper towel , because it is readily available and retains moisture well. Place a damp paper towel on a flat surface. Place the seeds in, spacing them a few centimeters from each other. Then cover them with a second paper towel. Both napkins should be fairly moist, but not excessively wet. When the white tips of the roots reach 2–3 mm, place the seeds in the pots. For sowing, follow the same procedure described above in the glass of water technique.

Sow the Seeds directly in the Soil

By planting directly into the ground, you will avoid and displace seeds while they are still fragile and delicate. The glass of water method and the paper towel method expose the seeds to temperature changes, so planting directly into the soil is much safer. First, fill the pots with top quality soil. Many growers prefer to add water that stimulates root growth. Drill a hole of 10 to 15mm, this will be your seed’s new home. Remove the seed from the package and place it in the potting soil. Cover the seed with soil, taking care not to compress it too much. The roots would penetrate the compacted soil more difficult, slowing down the growth of the plant.
