Firstly, there are many Dog seeds in circulation, many of which are not S1's of the Dog that I run. I have never grown a 15 week Dog strain, and I trully suspect that the Dogs that have been grown to this length are perhaps crosses of something else.
And you are granted your opinion, Lemon but as I stated, how on earth can you stabilise an S1 strain short of introducting and back crossing with another strain.
So, on to the stabilising of the Dog strain, the BX range. There has been work done on the dog with backcrossing from a male that came from an OG of similar linneage. The resulting seeds have produced good results with only the odd plant showing any sign of producing herm traits.
More work will be done on this strain in the future. I just do not have the time or space to do that....things are changing on that front.
So what I should be saying is, if you want Fire, then buy a pack and do some work, or get a clone from someone that doesn't have the issue. OR continue with Chemdog.
Slainte.
