Well, ojd is a haze lover and by most everyone's opinions he's a good seed maker so that strain should be good.
In that icmag grow journal, I would've let those plants go longer if it was me. They weren't finished with flowering. I'd guess they should go 70-100 days and probably more like 80-100 days and maybe even a little longer, but probably not. You'll do no justice to nice haze plants like that cutting them early. They'll still be pretty good if you do, but they should be REALLY good if you let them finish properly. And just FYI, far leaning sativas are good with a short cure, but are most often better with an extended cure. Stash a little for a 4-6 month cure and see if the effect is better; my guess is it will be.
