If u could check it up more precise? -12 hours keeps her in flower, 12 or more could reveg her. Furtermore your plant is perfectly suiteble for "obscuring" just give her 11 hours of the daylight and darken her up when its getting dark for two hours, when u go to bed its dark outside so you can remove the lightshield before u go to sleep. But hey if your under 12 theres no need at all
