i like the site you posted rusty.. very interesting
i dont have any proof but my mother has an amazing garden...not MMJ..but still HUGE and come spring i will post pics of it for ya'll (its under a foot of white shit right now) and she DOES subscribe to lunar planting and it SEEMS to work for her...
maybe it was just a great way to time your planting and harvests in the old days before they had modern calanders and such but it probably does have a basis in fact.. most MYTHS do have a basis.. or they wouldnt be perpetuated so much
just my thoughts bro and i WIL find proof for you
