not a true F1 I'm afraid, here is Mosca Negra description:
I have been getting this question about the F1 seeds. Well, the F1 designation does not really apply here since the C99 lines were developed with different environmental pressures on each C99 line by two different breeders both with different goals when breeding. Since C99 came from Jack Herer, which is itself a poly hybrid, separate lines from the same source can end up very differently even though they are from the same genetic family.
My lines were developed from distinctly different C99 F4 and F5 lines. I brought these two different phenos of the C99 lines to improve on the strain and to avoid the breeding depression that was becoming prevalent in the lines.
The use of the F1 term is one that may not be perfect, but makes sense and is an easy to understand term to use,when one looks at the parents used in the breeding of my seeds.
I will still pm you when I run them.
