I would say the grand daddy purps should be a blunt smoke. The Blue God is very rich in crystals, in my opinion that should be smoked and tasted without the tobacco overpowering the bud. Good find!
I have been growing blue god for a few months now and although it is not a great producer it is some of the best smoke I have had. Very strong, expanding smoke. Great aroma.
Currently have it in my garden and damn. The nugs come out super frosty and purple with alot of other colors. Grab the Ken's Granddaddy Purple if you want a guaranteed top notch GDP strain.
