Auto Flowering Light Question

I have some plants running that I let veg for a month on 18/6, then switched to 12/12 to flower. I know they would have flowered on their own eventually, but I figured what the hell. They have been on 12/12 for a month now and they are doing fine; however, I'm running out of time. This was my first grow, and I underestimated the time it would take for the plants to be ready. I'm moving out soon and am afraid they won't be ready in time. I was wondering if switching the lights to a longer light period would make the process go faster.. or if there is any other solution?

More light now the better. You want them to mature and light is the great maturer.
Before I set up another room I routinely grew autos and non-autos together. I would
veg them all at 20/4 for 5 weeks then switch to 12/12 for the non-autos. The autos kept on
growing and maturing at a slightly slower pace. I would guess that 6 weeks at 12/12 for
autos would be about the same as 5 weeks at 20/4, growth-wise.
