Yer for sure. Its a photo though so im hoping to get em into flower before the cold weather starts properly. If not i got a fan heater which ill put outside the tent blowing into the intake. Itll be on a timer though only coming on at lights out.lol when I do autos there done outside and they get 5 hrs. of sun so they don't get big this one was 15in tall and I would say 1/2 zip maybe if you really want them to get as big as they can they need 20 hrs.of light im waiting to see how that amnesika ends up its a good looking plant!
