Speeding up ripening process

I would not mess with the photoperiod of the plant by changing the light cycle, you can't rush it with lights. you will only stress it out more and that could have negative effects on your yield. You could try letting it get a bit warmer in the tent as things speed up when they are warm but you are most likely going to have to wait or chop a bit earlier then expected if your in a rush. Its not the end of the world, it will still get you high and be a great product after a nice dry and cure. The high may not be as couch locking if you like a lot of amber, but if you don't like that then chop em with the rest it will be fine. Good Luck!
