My last harvest I had the same exact conditions. On the third day I put the buds in a
paper bag for 24 hours to slow it down a bit, then into the jars.
Actually, it will not flower until it is mature enough to do so. Generally, this takes
about 30 days give or take. You might as well give it plenty of light for about three
weeks then 12/12.
Good luck!
I found this video on this subject: YouTube - THC Seeds - How To Grow Marijuana (4of4) Weed Cannabis Ganja
Sorry guys and gals. They switched the video on me. Will try to find the correct one.
Marijuana is an annual plant. Like Danny said you take clones off
of your known female and the cutting will be the same of that
the mother plant. Some say regeneration is possible but it takes
longer than if you were just to start from seed or clones.
