what they're trying to do is a corner cutting curing process. Also known as wet curing. I actually just wet cured over 2 ounces.
You just soak your bud in water, i put mine in mason jars, changed the water out twice a day until it was clear (about day 3-5) and then dry.
The reason they do this is because of the sugar leaves. That's where you get your harshness, but most of those chemicals are water soluble and thc isn't. You will lose all of your flavor profile doing this. but it will smoke smoother and be less noticeable.
I did notice the high was not near as long yesterday when I tried the water cured bud.
The more I read, the more I believe flushing is a complete myth. There is nothing you can do to take away from the harshness of the sugar leaves except to power through it or cure it. simple as that.
I don't understand the point of flushing. If you use all organic stuff anyways, and it still has to be broken down by the microbes in the soil to be absorbed by the plant, so why put your plant through the extra stress? like what is the actual benefit besides someone wasn't using their head one day and didn't think it all the way through? Last i checked we wanted those chemicals up there to make thc...
I'm learning with you dude. This is just from my observation and research. please correct me if I am wrong.
