how much longer til flowering

Ive been at it vegging for bout 4weeks now and j was wondering when will i notice signs of it being time to flower this is my first grow in 3x4 grow box under 150 watt cfls heres a pic

Hi mate

If this is a auto flower you will start to see some signs of flowers whenever its ready
if not it will stay in veg till you change the lighting just remember to keep in mind the height of your room and remember that your plant will most likely double in size once you change the lighting so if your looking for a sign or a time to flip that would be it take in to account your space form the light to the plant as well

if that made no sense please forgive me i am high at the moment best of luck and well done with her so far she looks nice and healthy

That made perfect sense. maybe cause im high too no its not an auto id say i still have about 2 feet of headroom since i started lst i was thinking bout letting it veg for another week or two but six weeks seemed like a long veg time to me ..

And thanks this is my first time actually putting some effort into growing haha
