Epiphyte species work biomasses are much more sensitive to different relative moisture levels than other plants.

Snow produced mechanically typically has high relative moisture content and low amounts of loft because the crystal structure resembles small, dense pellets.

Relative moisture levels indicate whether a gas is "wet" or "dry," while carbon dioxide levels tell the distributor whether the product is "clean" or "dirty."

The avoidance of overhead watering at night, using drip irrigation, reducing crop density, and using fans to circulate air flow will lower the relative moisture and decrease the severity of rust infection.

Following each individual brick should be a layer of adobe mortar, recommended to be at least an inch thick to make certain there is ample strength between the brick's edges and also to provide a relative moisture barrier during rain.

Number of days with relative moisture above 80% is greatest on Puntijarka (158 days annually), and it decreases with the decrease in elevation, for example on station Zagreb-Grič it is 67 days annually.
