Keeping this in consideration, how effective is cloud seeding?

'Cloud seeding' not effective at producing rain as once thought, new research shows. To encourage rainfall, scientists use "cloud seeding," a weather modification process designed to increase precipitation amounts by dispersing chemicals into the clouds.

Additionally, what does cloud seeding look like? Cloud seeding—sowing clouds with small particles to make them rain or snow—has a reputation as dodgy as the weather. Particles like silver iodide can provide a scaffold on which water molecules can align themselves into a crystalline structure or, in other words, freeze.

Likewise, why Cloud seeding is bad?

And in response to concerns over the danger of spraying chemicals into the air, Langerud says, “Cloud seeding chemicals such as silver iodide have been proven not to have negative impacts on the environment in the small concentrations being used”.

How long does it take for cloud seeding to work?

The onset of seeding effects can range from almost immediate to up to 30 minutes depending on the seeding delivery method (direct injection at cloud top, or base seeding - releasing seeding agent in the updraft below the cloud base).
