5 pages, 4 figures, title changed, a few content changes took place for clarification upon referees request. This work was finally accepted for publication in Phys. Rev. E. See also, the article entitled "Physicists Solve Cloud Formation Puzzle" that was written by Technological Review published by MIT (http://www.technologyreview.com/blog/arxiv/26105/) giving a lot of attention to our work

Assuming perfect collision efficiency, we demonstrate that turbulence can initiate and sustain the rapid growth of very small water droplets in air even when these droplets are too small to cluster, and even without having to take gravity and small-scale intermittency into account. This is because the range of local Stokes numbers of identical droplets in the turbulent flow field is broad enough even when small-scale intermittency is neglected. This demonstration is given for turbulence which is one order of magnitude less intense than is typical in warm clouds but with a volume fraction which, even though small, is nevertheless large enough for an estimated a priori frequency of collisions to be ten times larger than in warm clouds. However, the time of growth in these conditions turns out to be one order of magnitude smaller than in warm clouds.
