Yes, they can.
Surest way is to shorten their night.

Easiest way to do that is tack on a couple hours of light in the morning, or evening.


Don't take much to "keep 'em awake". A couple CFLs would work jus' fine.

As the days get longer you can cut back on the artificial light.

In Hawaii we can do re-grows outdoors.

Actually harvest buds and let them re-veg and re-bloom.
Jus' gotta get the timing right.
I've got a Thai plant doing a short season re-grow from a discarded rootball!
