Not enough of a difference to justify waiting an extra three days for some killer looking smoke,congrats!Chop now enjoy sooner! If you got more than one ready for the chop,do a test for yourself.. dark period one,chop one now.Let us know which is more potent,if you get more trichomes.I believe only trichome degradation will start and that the difference lies in the ambering of trichomes which will give a more "body,couchlock" high as opposed to a nice "head,uppity" high.
