cfls help please

will i need ventilation for a 250watt cfl envirolite,if growing in a cuboard lined with white black reflective sheeting and a open door the growbox will be in a small bedroom wich i plan on leaving the window open for fres air.

Not necessarily. But yes get a fan. I've been told it's very helpful. I can't find one and mine are fine, but I bet they'd be better off with it.

def want a fan to circulate air in the grow area. Also makes for stronger plants.

phillips right,its always better to have ventilation and the airflow will make stronger stems
