I sent you a private message, in my rep to you, but I'd like to clarify more fully. Sativas are a completely different animal than indica or hybrids. They can be very fickle. I had a great plant once. It was the best weed I ever smoked. It took 18 weeks to ripen. I never let a plant go so long/ripe. It was because the buds were so small, I kept hoping they would explode in size at the very end. They didn't. One day they just looked done. I could not find a single white pistil, and all calyxes swelled. I still did not find any amber resins. I don't even think there were cloudy ones. The smoke was phenomenal. Mind blowing really. The first time after smoking it, I did not trust myself to drive. It was so trippy and I was not sure the high was not going to continue to increase even after the first hour. I was just getting higher and higher the whole time!I don't know. I ran two packs of the regulars and found nothing worth cultivating. The genetics are obviously worth something for breeders purposes, but the regular seeds were very very disappointing. Some of the worst weed I've grown. And I've seen others grow it and wind up with about the same. So I'm not sure where the hype came from. Maybe the fems are better?
The next time I grew it, I got too tricky. Instead of going 12/12 light cycle for the entire 18 weeks, I dropped it to 11/12, then to 10/12. It shortened the ripening time to 16 weeks. It turned out to be hay. It wasn't worth smoking. I will never go lower than 11 hours of light while flowering again.
I had another sativa plant. It flowered it for 9 months! It never did stop throwing white pistils. I did get amber resins, and lots of them. The smoke was not very good. When I grow that strain again, I'll probably harvest it at 7 months because that is when the aroma turned to a incense/frankincense type of aroma which started to go away after a couple of weeks.
I think most of the growers on this thread are better indoor sativa growers than I am. I notice they let those buds get very ripe. indica hybrids are very forgiving with regard to ripeness. In fact, I prefer them harvested a touch early because I don't like "relaxing" or facial muscle drooping weed. To get the best out of a good sativa, or even anything worth smoking, one must learn how to grow it, which can be very different than other sativa plants. I've been growing for almost 50 years and I'm still learning. I think some of the popularity of indica hybrids is that they are so simple to grow. It is hard to mess them up.
Most people don't like to go into these explanations because it often causes disagreements. In fact, you may be more experienced than I'm assuming, and if that is the case, I apologize. I'm just trying to help. I wish someone helped me long before I accidentally stumbled into being a better sativa grower. Perhaps I just didn't listen well. I always need to know why, before I trust and just try. This may explain one reason for my long wind. Haha!
Another quick point. A long cure is very important to quality and potency. Some bud is just "meh" when you first sample it. Smoke it again 6 months later, and you can be surprised. I grew some Miss Universe last year. It was decent, but I decided it was not my style of high. I smoked it 6 months later, and it got much more cerebral. It still is not my best weed, IMHO, but it did get dramatically better.
