If you think flushing works.....please do so.......as someone on this thread said....there are many different ways to grow herb..........but think about it for a minute.... if flushing is necessary for the reasons put forth.....why does no other crop we consume by eating, smoking, of drinking need it? Fruits, vegetables, grains and tobacco all have taste issues and are not flushed before harvest and consumption! Think of the massive amounts of fertilizer, both chemical and organic dumped on all kinds of grows every year......you don't think they would need flushing??
