Their are a number of different techniques I use to push along the last couple of weeks to get to harvest quicker! One good one is Stalk splitting I actually take a knife and at the base of the stalk I jab the knife through it and I insert a couple of tooth picks through the stalk to hold the opening. This harms the plant and causes it to heighten its natural defenses which causes it to speed up and actually increase its THC and Tric production which are the plants defenses Increases dark time in the last week will aslo aid in speeding up the plants finish. Now this is just from my research and these are not proven techniques but from my experience I find it to help me quite a bit indoors. Not everyone will agree with me on this and thats ok Im just saying it works for me.
