I spent most of the day pressing the hash from my last harvest. I separated it into two grades of hash, 45-73 and 73-120. Normally I press the 45-120 all together. In the end, the 73-120 not only produced a visibly better looking rosin, it also produced more rosin per gram of hash. By all stats, the Chem91 x OSD #2 plant produced the most rosin, and will be my keeper plant.
C91 x OSD #1 5.17 grams 73-120 micron
C91 x OSD #1 2.03 grams 45-73 micron
C91 x OSD #2 8.7 grams 73-120 micron
C91 x OSD #2 2.37 grams 45-73 micron
C91 x OSD #5 4.05 grams 73-120 micron
C91 x OSD #5 1.35 grams 45-73 micron
