blech no thanks on PGRs rock hard buds that taste like nothing. Cannabis is just like other fruiting bodies in that when you use something to enhance the size you usually will take away from other things such as flavor. Think eating a tomato that you just get off the shelf at a grocery store vs one that you grow yourself in organic soil or that at a farmers market. do that taste test and tell me you cant tell a difference... better yet use potatoes... organic potatoes have so much FLAVOR vs a regular mass produced one that just tastes like filler... because thats what it is filler. I have no science to back this up just my own taste buds.
