How many different types of precipitation occur naturally in the atmosphere?

Suppose I have an environmental chamber in which I want to create as many types of precipitation as possible by actively changing the temperature, pressure and humidity. Though obviously not big hail. As well as reverse processes including sublimation.

What combination of test parameters do I need?

I expect the speed of change too contributes to whatever phase transition

or rate I should say

Would you also need artificial mountains and ability to create winds as well or is the chamber too small for this and do they even scale down

No significant wind allowed.

So ideally all of fog, mist, dew, frost, drizzle, light rain, light snow, sleet, graupel, hard rime, soft rime, hoar frost, and perhaps half a dozen others that I’ve never heard of.

I’m interested particularly in how low I need or want to take the air pressure (too low and the environmental chamber would have to be made very strong).

I’m also interested in how much colder the walls have to be than the air.

And how big a chamber I would need to get real snow.

Getting closer to needing an answer here.
