flowering

when is the earliest i can switch the lighting to 12/12 and put them in flowering?

from seed if u want...

my plants are a lil bit more than 5 weeks there almost a foot tall how much more would they grow in flowering?

up to 3x their size now. Usually closer to twice.

i started flowering mine at 1 month old!

id do 4-5 weeks, each strain is different, where u buy the seeds should tell u if it doesnt then just do 4-5 weeks then turn to 12/12

Its just all up to u how big and how much u want in the end,, a lot depends on the strain for how much yield u will get,, its common around here for ppl to veg for 4-5 weeks then flower,,, but u can flower whenever u want... just dont want them to get bigger than the space u have, but, even then there are ways around that...

yeah i switched mine over to flowering and it has grown to touch the light so I have it off to the side. i posted in another thread (sorry if I'm jacking) but one person said to crush the top of the stem and tie it over with pantyhose. The stem is really thick cause its a white widow. i tried to calculate it doubling its siize but with the nutes I'm giving it I think its growing like crazy. tons of buds though
