Dood theres no real specific time you can and can't grow pot where you live really. Just as long as nighttime temps don't go under 60 f your fine, especially if your transplanting relatively mature plants (indoor germination). As to when your plants will be done that depends on how many hours of light your area is getting, full flowering will begin at about 12/12 hours of light and darkness. How many weeks from that point comes from the strain your growing, the more indica types are gonna be about 7-9 weeks whereas the sativas are gonna take 9-14 really.
