Why do hydroponic loofah leaves curl?

Most people have probably eaten loofah; even if they do not like it, they still have a fairly clear impression of it, because loofah's texture is very distinctive, very soft, very easy to digest, and when chewing it you can also taste the fibers inside the loofah. Loofah is also very useful. Besides being used as a vegetable for stir-frying, after loofah is left out in the sun to dry it becomes loofah sponge, and loofah sponge can be used as a dishcloth. Of course, this is only how it is used in the south. After coming to the north, you will find that some restaurants collect loofah sponge and use it as a soup base. Still, using loofah sponge to make soup gives a very distinctive taste; at least the idea is quite novel. The loofah seen in the past all grew on vines, and usually a trellis was set up for the loofah to grow along. However, there is now a new method of growing it, namely hydroponic loofah. What is hydroponic loofah? In plain terms, it means growing loofah in water.

1. How exactly is hydroponic loofah grown hydroponically? In fact, ordinary households are not advised to try hydroponic loofah, because hydroponic loofah has relatively high equipment requirements, and ordinary households cannot manage the aspects of cultivation equipment and watering devices. However, if you are not too concerned about the results of hydroponic loofah, you can also, like with other vegetables and fruits, add nutrient solution to water and then put in loofah seeds. Before sowing, the seeds must be dried in the sun for one to two days.

2. Does hydroponic loofah have temperature requirements? Of course it does, and hydroponic loofah actually has very high temperature requirements. During the day it is best to have 20°C or 30°C, and at night it is best not to go below 10°C. The temperature difference between day and night must not be too large, otherwise hydroponic loofah cannot adapt and will rot, so if you want to grow hydroponic loofah it is still very difficult. Without the assistance of a greenhouse for growing, hydroponic loofah may really not succeed. If the temperature difference between day and night is relatively large, hydroponic loofah cannot store nutrients at night, and leaf curling may occur.

3. How often should the water be changed for hydroponic loofah? There is no rigid requirement about how often to change the water, but if you see that the water level in the hydroponic loofah container has dropped a lot, then you need to water it. It is best if the container can maintain 60% to 70 moisture for a long time, because hydroponics after all cannot compare with growing in soil; many nutrients still cannot reach the standard of soil, so you can only work harder on the water. However, it should be noted that during the process of growing hydroponic loofah, if you need to water, it is best to choose the morning period. It is best if hydroponic loofah can be exposed to sunlight for half of the day. In addition, the container used for hydroponic loofah is best if its bottom has four or five small holes for drainage.
