Samlyle, I can't think of that term to save my life (its been nearly 40 yrs since I studied plant/animal genetics). But what you have is a new strain that breeds true.
-- Humboldt, I agree. Think you've found what you're looking for. Reserva Privada has a good rep for preserving & providing those old school genetics. I like crossing RKS to Big Bud. (I mean REAL Big Bud, I've bought seeds that just WEREN'T! ). What I got was the same high, taste & smell as RKS, on shorter faster plants. But then again, that's to be expected when you look at what Big Bud is
-- A little tip to both of you. Here's how to keep your hybrid vigor. Male & female mother/father plants to clone from. Each time you want to produce those vigorous seeds, put a clone of each into flower & breed them. Mass produce F1 hybrids while maintaing hybrid vigor. Store seeds in fridg, air tight container with silicon pk, they will stay viable for years. Humboldt, you can go this with your best M&F from your RKS & help preserve that wonderful strain.
