Dude, don't freakin try it, it ruins your smoke! I used those same exact instructions, about a year ago, and wasted 100 grams of green buds. It turned out horrible. Yeah, it got you high, but tasted like shit(barely tastes like weed at all), and was nothing like those instructions lead you to believe. Personally, I think it's a practical joke.
No, I don't make any mistakes, either. Those instructions were followed EXACTLY.
I couldn't even give the shit away, after it was "water-cured", so ended up making hash out of it.lol
