Maybe ... sometimes ....
generally one of the traits overpower the other. It's never sold mixed like tobacco is. When people are talking about the characteristics, it's basically parentage and breeding.
Okay, here we go, I love this shit not only because it's smoke, but because it's botany, and there's a couple really famous strains in here. I could break these down in detail including history but I'll save you the boredom and make it quick
Example:
1 - Magic Mango = Somango X AK-47.
2. Somango = Big Skunk Korean x Jack Herer
2. AK-47 = Columbian, Vietnamese, and Mexican Sativa x Afghani Indica (strain history is shaky, probably an accident)
3. Big Skunk Korean = is a cross between two unknown hybrids. Most likely new world and Vietnamese sativas and old world Afghani indica, much like the AK. Many of these are the building blocks of most American Smoke.
3 Jack Herer is Northern Lights 5 x Shiva Skunk x Original Haze crossing,
4. Original Haze was a Vietnamese Sativa base,
4. Northern Lights, used those same building blocks as AK. Northern Lights though was bred for colder climates. It's the ratios that make the differences.
4. Shiva Skunk was a Skunk F-1 x Northern Lights cross.
5. Skunk F-1 (is what happens when growers replicate and breed the byproduct of a bunch of stoners in 1960 and 70's Cali throwing their Mexican, Vietnamese, Afghani, and South American seeds on the ground. Letting Mama Nature take over for a few decades and saving the best of the best and refining it.
The formulas (what ratios, which parent) are closely guarded secrets.
