Double grape is touted as pretty heavy in thc if you’re looking for a more recreational strain.
White Crack is excellent, very potent! I'm sure Grapey Walter is too. Anything mixed with White seems to be frosty and potent. Although the White Train seeds I got were the 1 exception to all Mephisto seeds I have done, they didn't germ. None of them. Someone else had the exact same thing with that batch. I have NEVER had a Mephisto strain that didn't germ. Clearly it was an old or bunk batch, I have 3 left out of 10. I will try to Germ them, for the hell of it. But I get 100% germ on seeds normally. So, cross my fingers and hope for the best with these 3. They are really small seeds, I don't expect them to germ given the history.Also have a white crack and a grapey walter. Grapey walter has that problem with frost getting everywhere! Couple more weeeks and I’ll be able to speak of them.
