Tomato ''Shimmer'' F1

* With the appearance of the second true leaf, the seedlings dive into peat pots or cubes, paper or cardboard cups filled with a nutrient mixture. The best, healthy seedlings are selected for picking. They are carefully removed from the seed box, a hole is made in the soil with a peg, and then a seedling is placed, from which 1/3 of the main root is first removed so that the root system develops well. When planting, the roots of the transplanted seedling are pressed tightly with soil so that it cannot be pulled out. Seedlings always dive slightly deeper than they grew in the seed box. When picking, the seedling is buried down to the cotyledons.
Pots with picked seedlings are watered generously with water heated to +20+25°C and shaded for a day. The temperature during the day is maintained at +15+18°C, and at night +10+12°C.
As soon as the plants get a little stronger, they are placed closer to the light. It is advisable to give the plants additional lighting to extend daylight hours to 12-14 hours a day. Fluorescent lamps are initially placed above the plants at a height of 15-20 cm; as the plants grow, the lamps are raised higher.
It is also recommended to carry out fertilizing irrigation.
During the growing of seedlings, three feedings are given at intervals of 10-12 days: the first - 10 days after picking. The first and second feedings are given at the rate of 5 g of urea, 40 g of superphosphate and 15 g of potassium salt per bucket of water. The third feeding consists of double the amount of fertilizer. For 16-17 plants, 0.5-0.6 litres of nutrient solution is consumed. After each feeding, water the seedlings (required!) with clean water to wash off the solution from the leaves.
When using fertilizing, you need to monitor the condition of the seedlings: with weak growth, increase the dose of urea, with strong growth, add phosphorus-potassium fertilizers.
If tomato seedlings are grown in boxes or insulated greenhouses, then you need to keep in mind that when removing seedlings from a box or greenhouse, a significant number of roots are broken off and the suction capacity of the entire root system is reduced many times over.
The remaining roots are not able to replenish the water consumption for evaporation from the surface of the leaves, as a result of which the vital activity of the plant is disrupted: the greater the discrepancy between the suction capacity of the roots and the evaporating surface of the leaves, the more the vital activity of the plants is weakened (this is why adult, well-leafed seedlings tolerate transplantation most painfully ).
Important: the age limit for tomato seedlings should be 60-70 days.
