When to count flowering

When do you guys start to offically count flowering. At the start of 12/12 or when those lovely hairs start to show (not preflowers)?

I count when i start to see bud formation

That means they've hit puberty.

I count from the start of the 12/12 period but some people do it from when they see the hairs..

^ What he said.

People count either
by the days from when they switched the light cycle
or
by the days from when the plant responded to the light switch.

Counting by when the plant responded to the switch is usually more accurate, since plants can take weeks to respond to the change in light cycle.

thanks everyone for confirming this, that question has been rolling around in my head for awhile

Shoot, plants will also show hairs through preflowering when they have been heavily vegged. So for that circumstance, I would imagine counting from when you switched the light and allowed the plant to go into flowering would be more accurate.

This is true but even if you have the preflowers and switch the lights, you still have to wait a bit for bud formation, of course its not that long of a wait when your plant is mature

it seems to be a landslide

It appears so

showing hairs, that's when seed companies count flowering so...it's based on outdoors flowering, you only know it happens when the male/female starts to show

the responses i've read from several breeders over the years, is that when they say 60 days of flower, they are counting from when they show sex, not the day they switch to 12/12. the number of days they state is just a general guideline.

so most of the voters for 12/12 to include myself are probly indoor and its just eaiser to count the day you flip the switch

I consider myself a newbie but I've counted both. hell I keep a count from germ to soil to veg to 12/12 then 1st sign of hairs... the bottom line is on a 70-80 day strain it took just that from first sign of hairs. If you look at my current grow (click sig) you'll see what I mean, all updates are from first sign of hairs. stay high.

Thanks everbody for their input, keep em growing

Starting the countdown on the first day of 12/12 is usually used for indoor growers

Outdoor plants can start flowering around 14.25 hours of daylight

Once you know when 14.25 hrs of daylenth is , add the flowering time of your strain +2 weeks to determine your approximate harvest date.

You add 2 weeks because once lighting reaches a level that will induce flowering, it takes nearly 2 weeks before flowers are actually produced and seen

just my opinion, flowering starts when you see the first signs of "hairs" and hears why.

Outdoor growers count flowering when they see the "hairs"
autoflower growers, same thing
12/12 from seed growers, same thing

but, really it doesn't matter since you harvest when the trichomes are ready.

rock on

First sign of hairs is when to start the count of flowering!
If you measures at the start of 12/12 it would be about 2 weeks longer than the breeders listed time.
I never keep track anyway cuz I always so baked I forget to log shit. I just go by looks hairs, trichs and color.

Once flippin your lights to 12/12 or my cheese only takes 6.5 weeks to b ready lol your plant realises after a few days that they need to speed up there cycle so its in flower even tho there is nt any hairs visiable they are stiil goin about there thing to gain pistals!!

Clones are different and flower faster. I'm sure your cheese was cloned. No photoperiod strain flowers in 6 wks after the lights switched
