Growing seedlings quickly, growing lettuce in an apartment without soil

The seedling grower has a water (nutrient solution) operation. Place the seeds prepared for planting (peppers, tomatoes, cucumbers, peas, beans, radishes, lettuce, etc.) in the growing baskets, fast and efficient.
1. Wrap the seeds in wet gauze for 3-6 hours in an environment around 15-20 degrees to swell. Those that grow the highest during this period will be planted;
2. Place the sponge (or coconut fiber) in the basket, place the seeds (chosen in point 1) 2-3 mm deep.
3. Pour nutrient solution into the container (Nutrition: 1 gram of Pétisó in 1 liter of water, or other commercially available nutrient solution in the appropriate dilution, the level of the liquid should be approx. 2 cm). Place the baskets on the bottom of the box. Put the planting box in a warm sunny place at 18-20 C.
4. After about two weeks, when the plant has 3 leaves, fill the box (about 9 liters) with nutrient solution.
5. Place the seedlings in the planting hole. Turn on the aerator to supply oxygen for 3-6 hours in several installments per day. Note the position of the buoy. The green is the safe water level, the red is the warning area (if it is in the red position, it must be filled afterwards).
6. After the appropriate root system has formed and the seedling has strengthened, carefully remove it from the growing basket and plant it in its final location.

If you don't want to plant them, you can leave the seedlings in the nursery. When the seedling grows, the nutrient liquid level can be reduced, which is good for seedling growth, it can be harvested after 4 or 8 weeks according to the climate and different types of plants, so we can grow fresh, crunchy, rich in minerals and vitamins all year round even in panel houses bird salad.
