I'm not able to watch YouTube videos or have access to the specific video you're referring to. However, I can provide some general information about moss and its ability to thrive in different climates.

Mosses are non-vascular plants that typically thrive in humid environments with moderate temperatures. They require a consistent supply of moisture to grow and survive. While mosses can tolerate some drought and dry conditions, they generally prefer high humidity and frequent watering.

In hot and dry climates, mosses may struggle to survive due to the lack of water and intense sunlight. However, there are some species of moss that are more tolerant of these conditions than others. For example:

* Some species of rock moss (e.g., Rhodobryum spp.) can tolerate high temperatures and low humidity.

* Air mosses (e.g., Hypnum spp.) can grow in dry environments with minimal watering.

If you're considering growing moss in a hot and dry climate, it's essential to provide them with the right conditions, such as:

* Shading: Mosses prefer partial shade or dappled sunlight.

* High humidity: Use a humidifier or mist the area regularly to maintain a humid environment.

* Consistent moisture: Water the moss consistently, but avoid overwatering, which can lead to root rot.

It's also crucial to choose the right species of moss that is native to your region and adapted to local climate conditions.
