Benzelsanswered grow question 3 years ago First of all= why? Why would you? If you do anything in the grow room, there should be a reason for it. Im guessing you have one, but let me stop you right there.
No. No you cant. Plants need rest cycles and growing cycles that mimic natural sunlight. Thats what the plants evolved over millions of years to grow under. Yes we can "hack" mother nature and produce growing conditions never seen outside in nature- think DWC and hydroponics. Cannabis needs more air in the roots than most plants yet we figured out how to grow it in fricken water !! But the one thing you cant hack is the light cycle, plants need rest after each growing period. But if this grow period runs too long, the plant will get stressed and start to do weird things. It screws with the natural hormones in the plant if you run the grow cycle too long.
Im sure there is some limit to the grow cycle where in theory you could run 24 hrs on and 7 off, or 22 on and 4.5 off, and just cycle it in a weird never ending series of timer resets... but no one has ever done the research to try and "dial it in" and figure out what the genetic limits of a cannabis plant is. If you increase the grow cycle to over 24 hrs then there must be a corresponding minimum rest cycle amount of time that also needs to be figured out. what I mean is if we know a plant can go 18 hrs grow and 6 hrs rest and be happy, then in theory if you grow 24 hrs straight then the plant SHOULD need 8 hrs of rest before the next grow cycle. So at 36hrs on you would need something like 12 hrs of rest before the next cycle, and that would induce flowering.
Now as far as I know , no one has looked into this as its not worth the extra effort=it wont produce more buds or better buds or buds any faster...maybe a touch faster but your going to lose quality so again its just not worth it.
I know u asked a simple question- but the more you know right?
