You should be able to save your grass patch to a file and scale it with 
something like :

   object {
     #include "fgrass1.inc"

     texture {
       pigment {
         dents
         triangle_wave
         color_map {
           [0.0 rgb <0.0, 0.4, 0.1>]
           [1.0 rgb <0.1, 0.6, 0.2>]
         }
       }
     }
     scale 0.08
     rotate 45*y
     translate <0.5,0.6,-8.0>
   }
