If you up it to a 24 hour light cycle it will twist up it's nickers and look a little funny for a bit, but will go back to straight veg mode and grow all winter like that. Next spring (if you keep it under a small fluorescent that's on all the time), it will be 2 to 3 feet tall and pretty healthy if you keep a fan on it for main stem strength, (occasionally, not necessarily full time with the fan).
Then you can put it outside when the sun starts having enough light to not have it immediately go to flower, and it will grow flowers again and this time will spring to huge well ahead of anything you plant in the spring. (Mine grew to 15 feet tall).
I found this to be a very labor free way to grow, it just wasn't a good match with the fungus gnats due to being too close proximity.
Moving them to another location solved that with a little H2O2 added to soil.
If they did turn out to be male, I take one branch and put it in a plastic bag. Don't let it leak near females, and when it's time to pollinate for seeds, just put the empty bag over one branch of your female plant just for a second and it will grow seeds on that one branch. Easy peasy, and guaranteed to work. The pollen is very effective and anything let loose in the air will grow seeds, (and rob all the energy from your 30% thc), so be careful with that magic wand.
