The Z7 came directly from Shantibaba, but I believe its a collaboration between he and others, as it was one of the precursors to what now is the CBD-Crew, so I believe he's working with Jaime from Resin, and perhaps others.
These last two phenos I've got are the last from my lone pack of Z7, I won in auction. Not sure if the strain will be ever released again. I sure hope so.
My pack chucked about 50% of the phenos being CBD-rich, in ratios from just under 1:1, all the way up to roughly 3:2 (CBD:THC), with some in the mid teens% CBD and around 10% THC.
The two phenos I have left are, sadly, not the best of the pack I grew out, but I had to let those mothers die when I moved across the country. The tastes were pretty incredible! The THC-dom phenos were pretty impressive themselves, and had a lingering orange peel taste/smell. The CBD-dom ones had a fruity/candy taste/smell to them, grew bigger flowers...also a very unique flavour profile.
