You place your buds in distilled water and change the water every day for roughly 7 days, in that Crouse of time you will see the PPMs raise over night slowly dropping lower on a TDS meter and at one point it will stabilize to around 8ppm, after that you dry your buds and they are ready to smoke, Thats it! No months of burping or waiting.
Yes it does take the flavor and smell of the cannabis away and I did not like it personally, kinda like smoking air and never liked the high i got from weed after a water cure.
