I have Ken's original GDP seeds along with f2's I made, got them when the guy that went to dungeon vault genetics was still with Ken. His partner actually gave me a couple free packs for doing a grow report on Icmag. Regardless of Ken being deceptive, the 'real' GDP cut being better and all that, the smoke I got off of those seeds was so damn good.
Not the strongest high, I would guess in the teens for thc. Super mellow and trippy sometimes as well. Not a downer type high at all. Hope Ken is doing well but suspect not. I have not grown or smoked GDP in years as I have been on a sativa safari, but they are certainly a great hybrid type of high for me and will get grown again someday.
