No, she does have a point.. I don't think quality options for seed purchases will diminish because of ruderalis influx, but local/commercial stock will end up with alot of these auto genes in them, and after a few generations of random cross-breeding, finer characteristics like the diesel-like flavor etc will have disappeared, but the ruderalis genes will still be in there to shorten flowering, and reduce potency..
Hap-hazard cross-breeding dilutes the local gene-pool with or without ruderalis.. Certain strains are considered 'true breeding' for a reason.. From a connoiseur's POV, more ruderalis in general will make the effect on potency worse as..
Bag seed will suffer like it did when indoor growing began and strains were bred for convenience inside..
I'm not going to knock the autos if even the F2 seeds are uniformly comparable to the purchased seeds though.. I see too much convenience for alot of situations, and if they have a true-breeding nature they could even improve local genetics for a while each time they are re-introduced, and directly crossed with the local outdoor strains..
I am ultra bummed to hear that dieselryder F2's aren't stable.. That kind of kicks that convenience I was talking about, and the truebreeding value right in the nuts
