Flowering: How long can it take ?

So i was just wondering what is the longest a plant can take to flower ?
ATM i have 2 plants just bag seed that have been in flower 11-12 weeks now and they dont look anywhere near ready to me so i just wanted a ruff idea if it could be 14 weeks or is it going to be like 17 -18 ?

14 should be the max you'll experience. you say it looks nowhere near ready @ 12 weeks? must be some equatorial strain... super skinny leaves? those jungle strains can be a real pain in the ass to grow.
another possibility is that your not getting enough light intensity. that can delay maturation big time.

Original Haze is the longest flowering strain we know of, lasting for over 110 days of 12/12. That's flowered properly. Problems can increase flowering time.

I had an Alaskan Ice that went 114 days in flower but I've heard there has been a lot of problems with that strain.

I want to see these plants do you have any pictures?

Hmm its looking like 2 or 3 more weeks but hard to say. To be honest, in a few of the pics I can see a heavy haze influence. Try reducing the light cycle to 11/13 or even 10/14 to see if you can speed the process. SHould be premium smoke
