3rd time grow. 7 bagseeds

This is my 3rd time growing. First two grows weren't bad. Both got up to a foot tall but were males. I don't have much experience growin but I grow for fun. If I knew how to upload a mobile pic I would
My tallest plant is about 3 inches tall and I have a few that are 1/2 inch tall. They are the same age. Does height determine sex?

nah man sex is determined by light schedule. If your outside once the days are shorter they will show sex. but you can induce sex by allowing 12/12 light/dark. they will take a few weeks to show for sure.

I'm growin inside but using sunlight. I'm waitin to get lights from my friend.
