twice its size? fuck so if its 7 foot its gonna grow 2 times that so itll be at 21 feet, dude it grows about 2/3 of its size but doesnt double itself, laugh, but yeah def gonna have a prob in flowering, the buds are gonna smash into the glass and get crowded and i can almost guarentee mold, so you really need to think of something to do, and i really dont think anyone here can help you, that green house is plain and simple too small, if theres nothing you can do, black the green house out now for 12 hours a day at the same times everyday and start flowering her other wise your gonna kill her and recieve nothing, that can be the case already since the nighbors shouldnt be allowed to see it. tough spot bro! a good experience for the future. not just for you but hopefully to the many following thispost. Bit she is healthy, good luck! -syze-
