I've ran JTR, Vortex, Nevilles Haze, Mango Haze, Super Silver Haze, Shit, Medicine man, Blueberry x Neville's Haze, Black Widow, and a few others, but those were the better ones. I am a Mr. Nice fan, and have spent a lot of money on Shanti's gear.
Out of all those, the only one that touched JTR was Neville's Haze and my Neville's Haze/blueberry cross.
And I can tell you hands down, in the last 20 years, the most intense, fucked up, trippy shit I have ever ran and smoked was a 16-week Neville's Haze strain. I don't know why you are on the Mango Haze train so bad, it couldn't TOUCH the Nevilles I had. Not that I think it's weak, I've just smoked a lot of shit that was AAA Grade.
But what makes JTR so great, is that after 9 weeks, I had top shelf smoke that was comparable to 12-14 week sativas. Maybe you should grow some more strains before hailing this one Mango Haze as the end-all be-all. Mr. Nice has other strains.
