Ok, i have 10 Lowryder 2 seeds, all have sprouted and growing pretty good. They were first put into a glass of water on the 30th of april and by the 3rd of May all 10 sprouted. I then put them into 4" pots and on the 6th of May all of have came up form the soil

at the moment there 4" in height and there is a strong smell coming from them, i put them out during the day and bring them in at night and there also in biobizz light mix. My question is, How long more do i have to wait to be able to tell what sex they are? and is there anyone growing them in pots outdoors?
Thanks and be safe.
