Can lettuce be hydroponic?

Lettuce can be cultivated by hydroponics or soil culture. Water needs to be changed every other week during hydroponics, otherwise pests will be induced, and rotten roots need to be pruned in time. However, the soil culture method of lettuce is relatively simple, the cultivation process is more convenient than hydroponics, and the plants grow very well.

Hydroponic cultivation method of lettuce

1. Seedling raising: When lettuce is hydroponically cultivated, the seedling raising process needs to be carried out first, and vermiculite is used as the seedling raising substrate. Before hydroponics, the vermiculite is soaked in water, and the seeds are evenly scattered on the vermiculite.

2. Planting: When lettuce is cultivated in water, you need to prepare a foam board, then drill a hole every 20 cm and put the seedlings in the hole of the foam board. At the same time, it is necessary to maintain the air permeability of the stem and reduce the disease of the stem.

Matters needing attention in water healthy dishes

1. Seasonal arrangement: Pay attention to the habits of lettuce in hydroponics. Lettuce likes cold plants, so the temperature in spring and summer should be controlled within the range of 15 to 25 degrees. Below 15 degrees, the growth is slow, and above 30 degrees, it is easy to cause poor growth.

2. Add nutrient solution: When hydroponics lettuce, you need to add nutrient solution and keep it clean. While doing a good job in disinfection of nutrient solution, we should update the nutrient solution once a month to prevent diseases.
