and yes i mean i grew them and seeded a female on 2 diff occasions with no luck on the seeds they produced and i gave half away with no luck either must b doing something wrong
I had issues with 'lowryders' when I first started breeding them also. Im at about the 800ish mark now... but I think I might know your problem
The original and LR2 strains I found always had a problem with 'stillborn' seeds, and I tried just about every way to conceive them, but the issue seems to lay in the ruderalis strain.
The ruderalis on it's own has very good success with natural pollination , but becomes weak when crossed with a more vigorous (smoking) strain.
As you create a strain that holds more characteristics of its THC based parent, success becomes higher once again, but you begin to lose the traits that make lowryder popular (height & life cycle)
I actually breed from pure ruderalis stains now and the most successful way is to 'bag and shake' the matured males for pollen and store in the freezer until your females are just starting to develop their flowers.
Apply with a small fine makeup brush (blush brush) and in a soft poking motion push the pollen deep into the lower parts of the flower.
This, in my experience, gives them a very strong and robust seed... and most importantly... virile.
Good luck
