Any suggestions!!

I am a newbie to growing so please help!!My plant is in week 7 and is looking mighty fine!! Its around 23" with around 40 leaves on it. I am now growing under a 400w HID but for 6 weeks it was outside as I only got light a week ago! I am now doing 12/12! Do you think not growing under a light for 6 weeks would of done any harm, and now that I have started 12/12 how long will it be till harvest time??

I dont know about bringing it from outside to in, but depending on the strain it could be around a month and a half to two or three.

Mmm.. Thats worrying me too, though it looks fine and has addapted well!!! Lets just wait and see?? :)
