do i really need a vent?

and im growing it where its kinda cold so do i need to put a heater n the tent? thanks add tip if you want

Seems legit. how much do you know about growing? knowledge is power so do some looking around. If your growing in a tent it shouldnt be a big deal on heat just keep it around 70-80'F. Any pics?

Def get a heater for lights out if you are growing in a cold area. The 600 watt light will keep it warm enough during lights on. Good luck. Have fun. And yeah ventilation is pretty key.
