Trimming off fan leaves before harvest

Not sure about speeding it up, as if your doing it a few days before harvest then they are already ripe and a few more days aint gonna change that. However there is a theory that a heavy defol a day or two before harvest can make the plant think its being eaten by some animal so it ramps up tricomes to produce more THC and resin as a defense mechanism. The trick is to not cut off all the leaves as then the plant cant collect energy to make the THC, so u want to do a medium to heavy ish defol a few days(2-4) before and then the day before do another smaller one and on harvest day u do the last defol and take off all the leaves left and then the buds in that order. I dont know if science has tested it yet, but I do that or something similar as it makes harvest easier and at least doest hurt if you dont go over board the first big chop. Say 50-60% of leaves gone on first chop, and up to u on the rest as it doesnt really matter after that. If u have two plants then test it out and try on one but not the other. But Im def a fan of using the stress from defol in late flower to boost resin and thc production. Its the timing u need to figure out as each strain reacts diff to it. Some like it, some love it and some hate it. Some seems to react well if u do it 2 days before but not 5 days before, ect. But if in doubt a few light ones each day for a few days leading up to harvest day is another way to give it a try and test the waters and see how ur plants react.
