The benefits that I can see right away would be the possibility of a seed or two forming, which are usually female and prized by many. A much more couch lock/pain relief/sedative type of effect no matter how Sativa dominant the strain may be. You should also get every last bit of growth possibile as you don't have to worry about chopping before the swell has been maximized. The negative effects I could see are the possibility of diseases, the degradation of some cannabanoids, and the chances of a few nanners forming and causing problems with other plants in the garden. Let us know your results when you are finished! Good luck to ya!
