I have yet to see a strain finish in the catalog time if I start counting from the day I switch to 12/12.Should I start counting the weeks as soon as I put in 12/12 or after it shows sex.
He basically said it all. There is nothing 'carved in stone' when it comes to breeders flowering times vs actual flowering time in ones particular garden. So many variables involved.It starts when your plants are beginning to produce buds not when you switch the lights. If it takes 2 weeks to start budding on a 9 week strain, you will be at 12/12 for 11 weeks.
