Early October for most of North America, but that varies on Strain as some go longer than the weather holds up like middle of November. She least 2 weeks and maybe 4 left to go, so not really close yet as they will fatten up more.
She's a beauty that's for sure, but you're only about half way there buddy as was said, by mid Oct. you'll be ready to check her...get a loupe they're cheap...I got 1 for 12 bucks, makes all the difference
@Justaguy44 , You should check out some of Mocha's outdoor grows. He grows some real beauties ! I'm really fond of the X-mas tree looking plant he grew. That one always pops in mind when I think of an outdoor grow.
August 20th and today is Sept 20th. If the buds started showing up on Aug 20th then the first pistils were probably just poking out about a week before. That puts the plant at approx 5 1/2 weeks into flowering. With many strains running 8 to 10 weeks under optimal growing conditions (usually indoors or in a greenhouse) then we can figure 4 or 5 more weeks to go.
Outdoor plants do tend to take longer going through the flowering stage. Cooler weather over the next month or two will slow the plant down but they can tolerate the cold nights and cooler days when there is cloud cover.
The best part is the last couple of weeks, when it seems like there is nothing new happening, the buds start to swell up some and become denser or heavier. It is an interesting part of the grow to be able to watch happen.
