Our grain growth model follows the dust content in molecular clouds and the inter-cloud medium separately, and allows growth only on pre-existing dust grains. At early times, this can make a significant difference to the dust growth rate. Above $z\\sim8$, type II SNe are the primary source of dust, whereas below $z\\sim8","authors_text":"Aswin P.
