This is the only thing I do not agree with.About 3-4 prior to harvest, stop watering all together and let plant start to dry out soil for easier and faster dry time.
Not only will the plant left in a dry pot dry faster, but it will sometimes be more resinous, because THC resin is also used by the plant to protect itself from drought...I always water as sparingly as possible for the last week...and nothing if harvest is only a few days away...This is the only thing I do not agree with.
I like this guySimple explanation to all this.. the lady you saw was a fuckin' retard.
You flush while in soil for 2-3 weeks prior to harvest with straight ph'd water. This will remove all trace chemicals and nitrogen letting the weed taste and smell as it should. It will also help burn the product evenly.

You have no way of knowing if she was a retard or not. Unless you have met her.It will work and also flush ur plant, but u need to change the water daily, and leave the plant for like 4-6 days until the fan leaves and such start to yellow out and die showing you are using the residual nuterient build up out of the plant, which is what flushing is for in the first place.
She wasn't a retard, just another one of those pieces of incomplete grow info on the interweb.
