the plants are looking great BBD....good luck with the WW cross....those should have some nice offspring....
Vito: using a brush is a method of pollinating that does not involve pollinating the whole plant....you use the brush to pollinate selected bud sites so you still get a good amount of seedless buds too....if you want more seeds either brush more small buds or brush a couple bigger ones....that's the way i make my seeds....i also harvest the buds when they are ready bud leave the seeded buds to make sure the beans mature....
