how long?

how long should i stay in veg before i start to flower

at least a month .. if not longer

do they look good

looks great. Also to answer your question it is all up to you. If you want a small plant that does not yield much you can put it into flower right now. Of course the longer you vegi the bigger the plant will get. GL

i have 10 fems that are 12/12 from seed right now and the whole 12 weeks they will be growing they will only reach about a foot tall. they still veg under 12/12 just slower. if i run 12/12 from seed they usually take about 3 weeks to show sex and 8-9 weeks after that to flower. you can stick a plant into flower when ever you want. normally i will veg for about 2 weeks then flower. you'll be surprised how big they will get with only 2 weeks of veg. sativas are going to get pretty tall, indicas not so much. if i dont do 12/12 from seed i usually always end up LST'ing my plants and i have about 4feet in vertical space to use. some strains that ive flowered after 2 weeks of veg grew to 4 feet in height. mostly sativas and 50/50 sativa/indica. it simply depends on your strain/growing conditions. peace.
