The requirement of soilless cultivation of tomato substrate humidity

2021-01-28

01 Seedling stage
Tomato seedlings require less water, high substrate humidity, high temperature and low light.Seedlings are easy to grow, and the substrate water content is controlled at 70-80%.
02 Slow seedling stage
The substrate humidity is about 90% higher, which is convenient for root growth and speeds up the slow seedling.
03 Early results
In order to prevent overgrowth and fall of flowers, 10 days after planting, before the first inflorescence sits on the fruit, the substrate humidity is controlled at about 60%.

04 Result peak
After the first inflorescence sits on the fruit, the tomato plant grows vigorously and requires a lot of nutrients. It is necessary to increase the amount of irrigation and the frequency of irrigation, and increase the substrate humidity to 70%.
05 late result
Tomato fruits are constantly increasing. In order to promote the growth and development of the next few bunches of fruits, the humidity is kept at about 80% to avoid lack of fruit to grow, and to avoid cracking of mature fruits.
