I say as long as you're not below 65 you're good...And yes some calyxes will start to show a blue tint in colder temps. Never been able to test it myself though, I live on an island and I'm not even able to bring my temps below 79, even with AC.
I'd have to say....3rd degree burns to me entire left foot...There is nothing worse than the pain of burns, I can only imagine how panhead felt. The pain itself is enough to kill a normal man.
Over here an ounce costs $800...I know it's fuckin' ridiculous...Which is why I grow my own shit. But you can make a killing!
