Any idea what the difference is between P98 and Katsu as far as lineage/history ? Sorry if this has been already discussed in the past!
musta's take on it is quite possibly true, although i have never seen an S1 of the pre-98 with quite the same bud structure as the katsu. Also the katsu seems to have a little more vigor than the pre-98
if i was guessing lineage just on the basis of the two cuts, i would suspect that they may well be siblings from the same batch of seeds or 2 pheno's from the bubba inbred line - originally labelled 'purple bubba' and 'green bubba' - but now called pre-98 and Katsu.
either way they are both great and having only grown out the katsu once, my theories might change.
