I just finished a run of the royal queen BLue mistic,i super cropped them,and got about 6 oz off each one the plant's were only three feet tall and around three foot around,it is killer smoke.very heavy smoke great taste to,but I personaly can't compaire it to the blue cheese cause iv never tried it,but the other cheeses i have tried were great,i found the mistic to be verey easy to grow.i used pro mix and some not so organic nutes,she gets a very dark hugh to her in the final weeks of flower,great plant IMO,but i think by the looks of og18s plant your going to be happy with either one.
