At present, there are many vegetable varieties that adopt the soilless cultivation, and hydroponic lettuce has fewer diseases and pests and high commodity value than the general lettuce in soil. Today, let's take a look at how to grow lettuce with soilless cultivation?
Vegetable variety selection and seasonal arrangement
Generally, in winter and spring, when the temperature is not high, the most suitable growth temperature for lettuce is within 15 to 25 ℃, and it will grow poorly above 30 degrees. The varieties of hydroponic lettuce can generally be loose-leaf lettuce.
Tenlead’s hydroponic Growing Cube is an excellent base for seedling root development. It is ideal for plant nurseries. It can be used as a replacement for the traditional seedling cubes made by rock wool or peat moss.
Agricultural Hydroponic Cube with holes retains moisture well, so there are fewer cases of water shortage. Agricultural Hydroponic Cube retains oxygen well, so overwatering is less likely. Agricultural Hydroponic Cube never hinders the development of the roots. Agricultural Hydroponic Cube comes in many sizes and shapes, so it can hold almost anything you want to grow.
Planting process:
Sowing
1. Sowing
Sow The Seeds. In this step, please put the seeds in the holes.
2. Soaking
Put water in the tray until the growing medium and seeds are fully saturated.
3. Shading
Covering the growing medium to keep the seeds in the dark, and waiting for the seeds to germinate. (There is no need to water during this period until its germination.)
Germination
1. Germination
After the seeds germinating, expose the seeds in sufficient light, and watering them moderately until the cotyledons grow. (Adjust the amount of water appropriately according to the temperature.)
2. Cotyledons Growing
After the cotyledons growing out, you could add the nutrient to the tray. Normally, you need to adjust the EC value to the range of 800-1000us/cm.
Transplant
When the rhizomes of the seedlings are strong enough, it can be transplanted to the planting trough. In general, the seedlings are strong enough to transplant after 2 leaves grow.
