Thanks for all the replies.
If it's likely to turn out male, then I think I'll be a little more patient and wait until it shows it's gender for sure. I'd rather not waste the batteries until then. Also, despite the advice of getting a bigger pot. I don't really have the room for it. And as I said, max yield isn't too much of a priority. I just want to get one successful grow under my belt. From what I understand, it'll possibly double in size during flower as long as I keep her (fingers still crossed) fed. So the estimated size is more than what I hoped for, for now.
I do have a couple of other plants on the go, but they're still in seedling phase atm. This week's weather has been a little colder and overcast, so the poor little mites aren't growing as fast, but it might be the strain. I bought 10 Skunk #1 seeds from Attitude and I hope they turn out better. Summer's here, but with the back and forth weather, I may just build a stealth nursery from an old PC case with fans, some CFLs and some mylar I have knocking around. If that goes well, I may have an all year pipeline with reasonable (80-90 day, perhaps faster) turnaround from seed.
One thing's for sure, I prefer the 'fire and forget' nature of soil grow.
Again, thanks for the help.
