Nucleation of droplets and ice-crystals, starting from aerosols, leads in clouds to the formation of very small particles, whose size has to grow by orders of magnitude to become rain drops or hail particles. The growth of droplets in warm clouds (in the absence of ice crystals) has recently received much attention. Here, I will discuss the problem of settling and collision of ice crystals in a turbulent environment. In the temperature range -20C
