Question about sealed room, a.c. an vented light

[Blazed227]

Ok so I'm turning my vented room to a sealed one.. the summer will be simply too hot for my shed otherwise an don't want to just suck out the cold air.. now I just installed 2 window units in my shed one 45 or 5500 but for the room with the 3x3 tent an a 6500 for the 4x8.. now right now I jave just a winged reflector.. if I were to switch to a vented hood well 2 vented hoods cause I'm about to add another 600 watt light how would I set the lights up? Fan to light to light to outside intake or cool with conditiond room aiir? That would kinda defeat the pirpose of a sealed room sucking from the room but will the hot outside summer air really cool enough to cool the light good enough? I had an 8 inch Apollo fan as my exhaust fan but gonna keep that hooked to my filter for air scrubbing.. Will a 4inch or 6 inch be needeneeded to cool the lights?

I use 6 inch for 1000hps . ok trying to get a pic of your shed .you have a shed with 2 seperate rooms in it correct . why dont you get a 10000 btu and cool the whole shed then you can run your lights with cool air cooling them and just vent the hot air I had to add a second inline fan to move the amount of air needed to cool my room in cellar during the summer good luck

Well I was going to get 1 bigger 1 but I don't have the money for 1, I just got laid off, an my buddy had these 2 brand new window units that he gave me for free.. plus it would be Easier to control temps with Sep thermostats in each room.. Bubut would have to suck outside air thru the lights corrext... otherwise the fan would just sick suck out the a.c. correct?

true so heres another thought put in and outside vent to the input to your lights then vent outside so yes you are pulling outside air thought your light and venting it outside . while still maintaining temps in rooms also how about a small vent from the underside of shed where temps stay cooler to provide fresh air to the girls. I started on a tight budget and its amazing what you can rig up to use . if you can give the girls what they need you can use whatever will work

Yea I already have a 4inch outside passive intake that's currently running, until I finish installing the other a.c. today..an that's what I was planning on doing just wasn't sure if it would cool the light.. but I guess it really doesn t need to cool it per say just suck the hot air out right?
