THIS THREAD on ICmag contains comments from Shanti (via kashgar) on characteristics of kush and how to select the Kush pheno's from the MKxSk line.
I wound up growing an amazing Kush plant in 1982 from seeds I got from a friend in Mt. Shasta, CA.
This was my second year growing plants and had flowered about 6 different varieties of indica by that time.
The Kush plant was very different in structure than typical indica.
Unfortunately, it was stolen before harvest and is now "the girl that got away" in my mind.
I have an old pic somewhere I will try to find and scan.
Nevil has said that kush strains in the MNS family originate from NL#2 x Kush4 (from Jim Ortega) and that both were kush type and bred true for those characteristics.

The confusion comes from the OG "brand" hype from CA and the incentive people have to call every indica hybrid they grow "Kush". Hard to tell exactly what the plant looked like when it has been through automatic trimmers and the nugs sit in a dispensary jar for a month.
It is very similar to people calling any old sativa hybrid "Haze."
There IS a "real thing" and not all of it is.
Hopefully it is a little clearer in that context.
In these days of poly-hybrids of unknown or intentionally misrepresented heritage, it is nice to know that there is a place to go where you can get the original foundation stuff that the other guys have built their BS on top of.
That (among other reasons) is why I chose MNS.
