Yes it will. I have completely stripped everything I could see off of a plant before and it revegged. I reccomend taking the plant and leaving some popcorn on the bottom and as many fan leaves as possible, put into a 24 hour light cycle. Flush the hell out of the soil and maybe even transplant into a larger container with fresh soil. Add veg nutes and maybe a little root vitalizer and you should start seeing plenty of new growth in about a month. Depending on how you cut them down they make great mother plants. I reccommend just taking a clone instead but its a great method if you have a keeper strain without cloning.
