Flowering question...?

ok..it usually takes about 1-2 weeks for plants to show there sex, right? And 6-8 weeks of flowering time....so do u count the week or two of sexing at the beginning of flowering or, after they show sex... Ex. turned lights bak on 6-15, and showed sex like around 6-27 or so.... so would it b 6-8 wks from 6-15 or 6-27...thnx in advance

yes, as soon as you got to 12/12 lighting, you start counting, the plants can take as long as 10 weeks to fully mature btw, 6-8 weeks is just a good place to start.
