Time issue

hi i was wondering if its at all possible to harvest a plant around mid to early aug if planted early may, which is about 12 weeks, because i have to go back to school. the plants would be outside the whole time and i live in southern pennsylvania. any help would be greatly appreciated, thanks

Nope not an oustside only plant.Youd just be coming to end of veg by then

when would i be able to harvest them

is there any way to force them to flower?

You can force them to flower inside or make some kind of dome outside where you can completely cover each plant to make it think its 12/12 otherwise your looking octoberish for natural cycle.Or if they are potted bring them in and start 12/12 for 7-10 weeks

would it be a decent crop at all if i were to come home on the weekends during october to harvest them?
