growing from seed

how long would it take for a plant that has been growing from seed to be mature enough to flip to 12/12

probably 5-6 week min cause i flowered mine at 3 weeks but all that did was add to the time there taking to flower check my grow in my sig

40 days minimum for most plants

really i flowered mine at 22 days and there still not budding and there at 34 days know so thats would be way about 40 day hay well thanks

20 days minimum
