Like 2 weeks flowering What you all think?

[LIP]

Here i am flowering with a 400w HPS on top and 2 70w HPS on both sides i use FOX FARMS big bloom and a great vent system.
On the last pic you can see the female flower how long does it take for these to turn into big flowers????

I guess you mean how long will it take untill harvest?

Well most strains take around 8 - 9 weeks to mature, but a heavily dominant sativa can take up to 10 - 12 weeks.

The only way to know when to cut the plant is to look at the trichomes though a 30x microscope or whatever they're called these days..

Read the faqs.

Also, how much space you got in there cos they will still have more growing left in them than you'd think.
