cloud seeding needs clouds to seed. And those clouds must be thick enough with moistier to have enough water moelcules to bond with the nuclei introduced by the seeding.

Here is a company that does it for hire.

Aerial cloud seeding is the process of delivering a seeding agent by aircraft - either at the cloud base or cloud top. Top seeding allows for direct injection of the seeding agent into the supercooled cloud top. Base seeding is the release of the seeding agent in the updraft of a cloud base.

there is more info at the link. And this is a for profit company, not some wiki info.
