i'm doing my grow in a cupboard/fridge. either way, its prob going to be around a cubic metre of space or less.
i've ordered a 5inch Ruck inline tube fan (275m3/hr), and a rhino 5inch (500m3/hr) filter will be ordered next week.
now, that should be plenty shouldn't it? is the rhino stated m3 the max it can do?
can you get too much ventilation??
