Experienced owners always follow the rule not to start growing tomato seedlings too early, thus avoiding problems with elongated plants and low survival. However, if you follow certain rules, you can grow strong and healthy plants in just 22 days.
The question of when to start sowing is considered in the context of optimal conditions for growth. According to the experience of growing tomato seedlings, the process takes 22 days, but it is important to follow several key steps.
The light regime plays an important role in photosynthesis, so it is necessary to provide plants with sufficient lighting. Starting with 22-hour daylight for growing tomato seedlings, it is important to reduce the length of daylight at different stages of plant growth. After the appearance of 6-7 leaves, the light day is reduced to 18 hours before transferring the seedlings to a 16-hour light day before planting in open ground. The level of illumination should be about 50 W per square meter.
Before sowing, it is important to carry out pre-sowing treatment. Enriching the soil with trichoderma biological preparations and treating seeds with a potassium permanganate solution are effective measures to prevent diseases and ensure seedling health.
If you follow all these rules, you will have strong and ready-to-transplant plants in about 22 days. Seedlings will be low, stocky and with developed roots – ideally prepared for growing tomato seedlings.
