agreed with resinous. The marijuana plant if running under 12/12 will go into flower as soon as it can which could potentially just be about 4 weeks, sometimes longer, sometimes shorter depending on strain. This would be ok if you're just trying to pump plants out as fast as you can but IMO if you're running 12/12 you are wasting a LOT of time and resources... You might as well plant it outside and say fuck it... The whole point (generally) of growing indoors is to be able to control your cycles and plants... When you only give them 12/12 you're not getting the most you can out of them... Try going at least 18, (my veg room runs 24 hrs on 220w of CFL's) and I guarantee you will see a big change once you decide to finally send them into flower with a 12/12 light cycle... Just ideas, to each his own.. REMEMBER MORE LIGHT=MORE GROWTH so whether that's more in the sense of time or in the sense of intensity there is def a way for you to get more out of what you got. THERE'S ALWAYS ROOM FOR IMPROVEMENT! Cheers
