Well it looks like i'll have to get the ball rolling myself! After spending aeons scouring the interweb for any info on the A5 Haze I have managed to come up with a rather loosely based theory on its origins/genetics, which is as follows: A5 Haze comes partly from one of Neville's original three haze plants, a male named A haze (the others were C haze, male and B haze, female). A Haze was hybridized with NL#5 to create NL#5 Haze. It seems NL5H eclipsed the other phenos which came out of this crossing, as there was another called C5 Haze (see where i'm going with this?) so i have to assume that A5 Haze is another pheno of the A haze x NL#5 hybrids. I know it sounds pretty ropey, but if you want to check my source. which is actually quite interesting follow this link:

If anyone knows better please don't hesitate to correct me! Also please add to this if you know anything else eg. growing traits etc.!
BTW I found some at a coffeeshop near me (maastricht) and it was damn good. intense green nugs speckled with bright orange hairs. Taste quite hazey but a bit lighter, not too musky. A very sativa taste.
