How long should vegetation go on for before switching to 12/12? I've heard many different things such as you start when your plant has alternating internodes and ive heard 2 weeks? Does it matter or is just to determine how large your plant will be? -Thanks
You ought to take a look at your canopy space and judge how full it will be if each grow shoot stretches into a nug.. If your canopy will be lacking if you flower, veg longer and get that canopy full!.. A full canopy is the key to a happy(fat) yield.. The smaller you flower your plants. The smaller your yield will be.. of course it all kinda depends on how many plants you have, whether your doing a sog/scrog/lst or just letting it grow.. it all kinda depends on how your growing.. But be patient while they veg, don't jump the gun into flower, you'll be glad you didn't when flowers over...
