How to grow Haworthia cooperi in a terrarium for greater translucency? Master terrarium techniques to improve transparency

After autumn arrives, temperatures drop and air humidity falls too. Many plant lovers complain that their Haworthia cooperi has been watered and given sun, so why is it not translucent?
It is actually because the air humidity is not high enough. You can try misting the Haworthia cooperi and the area around it every day to raise the air humidity, but the premise for doing this is that the environment is well ventilated.
There is another method: you can try terrarium growing. Many people say that a Haworthia cooperi that has not been grown in a terrarium is not a good Haworthia cooperi. Through terrarium growing, we can increase the translucency of the Haworthia cooperi.
It is now autumn, the growing season for Haworthia cooperi. Use a transparent colorless beverage bottle with the top half cut off to cover the plant for care, so that it grows in a small environment with moist air. This can make the leaves plump and the transparency of the "window" even higher. But in the high-temperature summer season, the cover must be removed to avoid the plant rotting from muggy heat, because the temperature for terrarium growing is below 25°C!
Notes on terrarium growing:
1. If the environment is very dry, there is no need to make holes in the top of the transparent water bottle, but it needs to be opened for ventilation for a few hours every week.
2. Terrarium growing is not suitable right after watering. If the potting soil is too wet, problems easily arise. It is best to do it about 3 days after watering. When there is water vapor on the cover, do not water; when there is no water vapor, water immediately.
3. After the temperature exceeds 25°C, do not stop terrarium growing all at once. It needs a gradual process. For example, keep it covered for a few days, then ventilate for one day, and slowly remove the terrarium cover and return to normal care.
