G13 Flowering Time

Does anyone have an approximate idea how long G13 takes to flower? Also what/where can I locate a good strain guide. I have several strains G13, bubblegum, matanuska tf, og kush, pre 98 bubba, and gdp. This is my 1st grow and I'm going to induce flowering today. I hope all these strains are ready to harvest at about the same time. Thanks for the help in advance.

I Would say 9-10 weeks.

You need to google all the different strains or look them up on a seedbanks site.
