Over the last year I have attempted to grow in an Aerogarden without much success. The plants seem very finicky and wouldn't last long. I'd practically given up. Then I planted in soil and the plants are doing well and are strong. One is nearly four feet high, the other two are trailing at 2 1/2 - 3 feet high. They had been under full spectrum lighting 24/7, until last sunday when I put them on a 12/12 cycle. They are in a wardrobe painted white inside and are in complete blackout during the off cycle. I have read a few blogs on flowering, some say 4 weeks others say 9 weeks depending on the type of pot they are growing. Since I do not know the strain that I have, how do I know how many weeks my plants will need to flower?
