2. Put the garlic seeds in the container, put the garlic neatly in the container with the bottom facing down, and then add water to the container until the water does not reach the bottom of the garlic, which is conducive to rooting.

3. Garlic can take root on the same day after hydroponics, and green buds can be seen in 2~4 days. At the initial stage of rooting and germination, it is not necessary to change water for three consecutive days, just add a proper amount of water to facilitate fixation. After rooting and fixing, the water can be changed more frequently, generally once every 65,438+0 ~ 2 days to keep the water fresh.

4. change the water. In the middle stage of hydroponics, water is usually changed every 5 to 7 days. In the later stage, the roots of garlic are easy to grow green algae. Clean the roots when changing the water. If rotten or shrinking garlic cloves are found, they should be removed in time.

5. The time of hydroponic garlic is related to the season. For example, the whole hydroponic garlic cultivation time in spring is more than 40 days, while the autumn and winter stubble is more than 60 days. You can harvest the first crop in about 30 days, cut off the garlic leaves and wait for the next growth.
