When can i start flowering?

Hey i want to grow chrystal by nirvana which is meant to have 8-12 weeks flowering time and i want to grow it within 3 months if possible under a 45w CFL i have grown big devil #2 (auto) with this light before and had great results =D i was wondering what is the minimum size i can flower it at? and does less size mean shorter flowering times?

sorry if these questions are noobie but i tried searching and this is my first shot at a photoperiod plant

Thanks

Bump please help me! =)

Do 12/12 from seed and you MIGHT be lucky to have it ready in 3 months. Also just 1 45w cfl?! Fuck me man if gonna grow good shit get more light. And extra 2 of them and you will notice a difference to previous grow.

Well can only run 45w light atm but the last grow i had with that light gave me bud that blew my balls off but i might get a few more in the future and thanks for the 12/12 from seed advice

In all honesty, your only cheating yourself with aa 45 watt bulb man.. Sure you'll get some powerful smoke with that bulb but your yield will be miniscule... Say with the 45 watt bulb you yield 7 grams... You throw a few more watts in there now, say 200 watts of cfl , your yield will jump up to around 30 grams or more.. Chrystal is a great strain with awesome yields... You will only cheat yourself with one bulb...
