There still isn't enough light in the day to properly veg a plant. If you plant now you'll probably end up with a plant around 12". If growing a plant for 3-4 months is worth only maybe a half ounce of smoke(if you're lucky), then go for it. If you end up with a male, the whole grow was for nothing really. The best thing to do would be to bring the plant inside when the sun goes down and put it under a grow light(or lights). You want to shoot for a total of around 18 hours of light per day. You wouldn't need to do that for the entire grow, though, just for veg. When you decide it's ready for flowering, just keep the plant outdoors until harvest.
