You sure it was that dude ? i also have a set up in attic and all is well with me, and scotland is colder than iceland lol, you also have to mind these things can grow wild the desert etc and those places drop in temp to -5 at night but the plant will still be ok, i also have a mate who does abit of outside work and has pulled them when ready with frost on them, they are weeds mind, might just have been a fussy strain, try CHURCH next time you could pour fu**ing diesel on those buggers and they'l still grow no probs, my advise to you is look into what your going to grow, do some research before hand all weed is diffrent, but if your going back to the atic id say church or doctor, nothing worse than a death in the family R-I-P That weed.
