Did you grow them indoors or
out? What kind of flavors surfaced?
Is red Kalamata not from Colomian origin or perhaps Mexican, brought in the early 50-60s to the Greek region?
What I read about the history of Greek Cannabis it was mostly hashish which was smoked round that and that Greeks produced big quantities of hash too.
The Kalamata looks resinous enough to be a hashplant originally, doesn't it?
Cannabis cultivation in the area goes so far into the past these might very well be local European/West Asian genetics.
So, might, could, we don't know really It does look good so far! Maybe we'll learn something.
