1. First, choose your own loofah. If you simply want loofah water, you can collect loofah water after planting for about 15 days.

2. Then cut off the loofah vine, find the main root, cut it at a position about 1m from the ground, and cut it obliquely, which will make the wound area large and produce more water.

3. The best temperature for collecting the loofah water is 28 degrees Celsius. When the air is humid, the water yield of the loofah water collected at this time is the largest. After cutting the loofah vine, you will see water coming out, and then insert the loofah vine into a sterile bottle without water and oil, so that the loofah water can be collected.
