chimera580---First off welcome to the garden.
I'm not the much for outside growing, but the skunk strain and 20 ft away, I'd think they will be thinking there are skunks in the area and smell that one for sure and if the wind was just right, most definately smell it.
Most places you get your seeds from having a sprouting ratio, and they usually run 80% or higher at least.
Now older seeds, then you have to take into account their age, how they were stored, and then most importantly how they are attempted to be sprouted, meaning indoors with paper towel method, or outdoors and just thrown in the soil and anywhere inbetween with so many methods.
Happy Growing
