Curious, need to know

Hi Grower, The Average Flowering time of a Gorilla is between 60-80 days.

My Gorilla Zkittlez auto from Fast Buds went a little over 11 weeks, I’ve got the finished diary if you want to check it out.

They advertise 9 Weeks, But all 3 times I did them it was 10 Weeks, plus or minus a few days. Maybe if I wouldn't "top" them, then LST and Lollipop, they might be shorter. I use a 3.9 G Autopot, with Athena Nuitrients, 50/50 Coco/Perlight and 77 to 80 Days is what I averaged. I know someone who gets less then the time advertised for 42 Fastbuds, But he uses 1-1/2 Gallon Pots, and doesn't stress them out at all, but it definitely effects his Yield, only getting about 6 Oz per plant.

All the fast buds stuff I’ve grown took several weeks longer than what fastbuds suggested

Removing all those leaves will slow it down. it takes as long as any other marijuana plant, if you start counting from a similar point. The myth around autos being 'faster' is a matter of comparing apples to oranges. If you don't count flower phase until you can "see" it, an autoflower has a ~10 day head start. 8-10 weeks will cover most varieties. An autoflower doesn't develop flower faster... it's just a marijuana plant that isn't dark-dependent.

How long do these normally take is a useless question. Every environment, grow style is different and it effects the plants differently, that's what dictates the length not what the breeder says. A buddy of mine grows a lot of cuts I give him and his grows of my clones almost always a few weeks longer than mine. And that's with actual clones nevermind seeds which introduce even more variables. Don't dictate the sched to the plant, let it show you it's sched.

Just ask @Fast_Buds 😊

Looks like you have a few week of bulk time left, nice buds. Stacked!

Search for diaries (you can filter harvested diaries). most have 13-18 weeks from seed with this strain. The time it takes highly depends on your environment, technique and even preference.
