First of all you have to calibrate the seeds, that is, choose the heaviest ones. To do this, pour into a glass of water, place the seeds of the plant there and stir. Those seeds that will pop up need to be thrown away. Change the specific weight of the water, add 1 tbsp of sugar to a glass of water. Remove those seeds that ended up on the surface of the water again. Rinse the remaining ones and dry thoroughly.
Also you can check the seeds for germination. To do this, take a saucer, put gauze on the bottom. Dry out the seeds. Moisturize the matter and cover it with seeds. Put the glass on top. Those seeds that will sprout in the early days are the most valuable. Etch them with 2% hydrogen peroxide. Heat the solution to 40oC, then place the seeds in peroxide for 8 minutes. Before planting, be sure to treat the seeds. You can use “Phytosporine” or “Energen” to do this. The immunomodulator will make them stronger and pest-resistant. To harden the seeds, place them overnight in the fridge before planting. This procedure should be carried out within 3 days.
Sow seeds into seedbeds. For this you can use small cardboard boxes, pots. The main thing is that there are water holes at the bottom of the tanks. In the store you can purchase biomass boxes. The material decomposes in the ground, so seedling can be planted with them.
Prepare the soil for seeds. It is best to use a fertile soil mixture bought from a garden shop. You can make it yourself as well. To do this, mix garden land, sand and sand in the proportion of 3*4*3 in advance. Be sure to sieve the soil through a sieve. If you want to grow strong and healthy seedlings, enter vermiculite into the soil.
Fill the substrate containers. Seeds need to be seeded to different depths, for example, tomato at 2-3 cm. To avoid getting confused, sign on the boxes the name and variety of the plant, as well as the date of planting.
Pay attention to the lighting. Some cultures are very light-loving. If the seeds sprouted, that is, the first leaves appeared, they need to stay for 14 hours in the light. Use daylight lamps to create ideal conditions.
Indoor temperature is also very important when growing seedlings. The optimal temperature is 22-25°C for seed germination, 15-18°C – for seedling growth.
Do not allow the soil to dry. Watch and ensure that the water is not idled in drawers with seating. For watering, it is better to use decayed water of room temperature. When watering, be neat, a jet of water should not knock seeds out of the substrate. To prevent this, use a shower nozzle. Water the adult seedling from the pallet.
