Both questions depend on a lot of things. When your first frost (if any) will come in (If it your buds can't ripen, it's not even worth it). When the photoperiod in your area switches to 12/12 (The only way you'll get anything is if you immediately flower.) If it gets stunted at all, you'll get even less.
Even in my area, which is quite temperate. If it doesn't rain for a week in the middle of summer, I have to water them every day. Smaller plants are even less forgiving when it comes to watering. But if your conditions are right and it's not too hot, they'll prob. be good.
All in all it will probably be a waste of time,
