how to tell time frame?

ok i have a plant that has been under 12/12 for two weeks and 6 days now and she just started showing her hairs 3 days ago i am wondering if i need to start counting on my flowering calendar from the first day i went 12 12 or if i start counting from the first day i saw hairs?

that subject is open for debate but not that important. the time to harvest is when the thrics get cloudy. seedbanks are just giving an estimated time to flower but your milage may vary depending on enviroment.

You need to be looking at the thrics. Usually it will be between 8-12 weeks with a multitude of factors in between. Like hydro or soil, nutes lighting etc. that finish a plant faster or slower. To watch the thrics you can go to radio shack and by like a $12 scope.

thank you very much im just trying to get an estimate of around when these will be ready to harvest as i am wanting to start a perpetual sog grow and need to know when to start adding the younger plants

i mark a calender from the first day of 12/12, but remember its not done until 50 percent of the hairs turn red/oranage on the top bud

Great. Do you already have clones?
