the moon is a good arguement, but you need to remember, the moon lets off a very very different (and for the most part unmatchable) light than our regular household lights that me and you use everyday in our homes, plants have adjusted to the moon over millions of years and have adapted to that light frequency, when you start throwing cfls and incadesants into the mix thats a whole new ball game. and gagekko also has a good point, hardier strains ( skunk1, NL, WW) strains that have been proven great will have a better chance of surviving traumatizing things during its life than 90 percent of the new crap breeders ares elling now adays
ps so are u saying the plant is to big for the grow tent? there are many things u can do to combat this as well, you can tie plants down, LST them, super crop them, theres always ways for them to fit bro, trust me on that lol remmeber then can grow any which way you point them, makei t a fucking jungle in there
