this is my first grow and not sure if i should change the lighting to 12/12 for flowering or wait longer.
i planted the seeds 4 weeks ago today. any help please
All about PATIENCE!! Heres my Arctic Sun mom, in flower now almost at 4 weeks in this pic... **You should keep a mom from plants you currently have(after they show preflowers ofcourse as would be kinda hard to pick mom now lol); an take cuttings from her; an than you can put rooted cuttings straight to 12/12 if you wish fellow grower** **Just my 2 cents worth as it sucks always starting from seed...**
Yes, they will get wider and if you top them they will get widerrr ( ofcourse size/width/growth ect ect all depends upon strain,ect ect ) Jus wait till they preflower than toss males away an than put female in bigger pot and turn light to 12/12 an change to bloom nute fellow grower... happy growing
Your grow, flip when you are ready. It looks like you should probably do it within the next 2 weeks due to space limitations.
If it was me i would wait for the 1st, then you know you started flowering 1/1/12
