I currently bought a 400watt light m h for veg. also a 2'4'7' tent thru sun hut. Now my question is exactly how do i wanna vent the lamp with the ducting with the can. i understand that you need to cool down the tent but does anyone have a blueprint i can go by? just a lil confused but ill keep searching. Just wanted to see if i could get some help. also if i run it 24/7 for whatever amount of weeks till i go 12/12 is my electric bill gunna have a noticable change? (still live with the parents)

Oh ya and i know this maybe be a stupid question but is it ok to stick a 250 watt bulb in my lamp even tho its for a 400watt lamp? reallly new to this and i wanna get good and i just need some help so i would appreciate all i can get thanks fellas if u can give me a hand:joint:
