How these look? 1st timer

you can grow 3 plants in there. maybe 4

10 plants is too much! some will grow taller and some wont grow cause of light lack.
they will be brushy and big as hell first you will flower them.

if you will flower them in low light conditions, from 5 females you will get less buds than from 2 females with good lightning.

PS use 40w to each plant.
you want to use more W's when flowering.
