Congratulations Rick45, that was a clear, concise, and right on the money answer. And a "newbie"! Rep+ for you Sir, you are a breath of fresh air in this forum.
If I may suggest, let's put away our calendars. We a dealing with a "Living Being" here, but the girls have neither calendars or watches.
Your smoke is ready for harvest when the girls say so, not when a certain date appears on the calendar. MANY factors play into when to cut. Strain, seasonal fluctuations, etc., but for me, it's all about the trichomes. When they are the color or combination of colors, THAT'S when to harvest. Last years grow, I cut a Great White Shark on Sept. 26 and last was Thai Super Skunk on December 7.
That would be a 2.5 month spread, and NO calendar involved....Trichomes.
Good luck & good grow.......BB
