what about all the pictures i've seen of cannabis that grows 8 inches in a month or whatnot

This is in 10 weeks, but with 8 weeks of flowering; the plant virtually stops growing after 2-3 weeks of flowering and fully concentrates on making flowers. Outdoor strains and outdoor grows can become huge in a few months.
Seedlings and clones grow slow in their first weeks because they have little roots and leaves.
