i've got 3 plants ,all at least 9" tall, and i really need to know how i'll know when to start the 12/12 light cycle

if you know they are females...anytime you want. just remember they will double or triple in size when you flip to 12/12

I 2nd that opinion. Anytime, but it will deffinatly be a rapid and great amount of growth as soon as you change over to 12/12. Good luck. Post pictures and start a journal
