Hey Pal, It was the seed version i grew so I could be wrong. The cut is not weak. Pretty decent from what I remember. Never grew it just smoked some from sheffield. Delightful terpy strain that was.
Yea I agree, I grew the Sheffield cut for years stronger than most and sold for £160 in the late 90's when it was rare to see anything go for more than £120.
When I left the UK for good I bought 40 seeds of bx2 or what they called killer skunk. I found a plant that matched the original in every way just very slightly less potent. This seems to be common when comparing seed lines to heritage cuts.
