5k if 15k is only needing 700 I should be well passed coved mine does close to 500 cfm

 

[DemonTrich]

Give it a go, you should be ok.

what u think is the best way to cool a light?

 

[DemonTrich]

Air cooled hoods
+A fan blowing the radiant heat from between glass and canopy tops

 

[Smerb]

what u think is the best way to cool a light?

Turn it off.

wow only 165 I would of thought way way hotter im trying to think of a way test the psi that is building up and being pushed out the back

That would be cfm and not psi.
You can check the cfm specs on the unit and find out all those variables. The fans are already measured in cfm. That psi you are thinking of is called your static pressure. All calculated out in residential a.c. systems. All.of that theory carries over into fitting supply and exhaust for ur grow area. 1cfm supply to 1 cfm exhaust is calculated as an air change per time period. All calculated. Google and u can figure out your air changes per hour.

I want to know how much pressure is building up in the box or if the air is just going up and out

 

[DemonTrich]

You should be able to get a spec sheet on your a.c.. Just look for some key words. Or hit up cannabisjohn. He's helped me out a lot over the yrs when I've upgraded, or set other rooms up.

Cut a peep hole in it that you can close. If air is blasting out there is more air than your exhaust fan can handle. I'm guessing the box is cardboard or something? Also you would notice hissing sounds as the box is pressurized. But I bet your fan is pulling pretty well. Did u say 700cfm fan?

 

[tinderthumbs]

this is what it looked like before hung it and what im really trying to find out what the cfm is of the air coming out of the ac and going up the tube like if I added a fan that is pushing 400 and if the ac is 400 is that 800 cfm or does it - it's self out?

 

[OGIBar]

No this is the exhaust right? For that set up its hard to say. Why so worried about measuring it? I would just go by whether the box is leaking or not. If its leaking then ur fan can't handle the air flow and your a.c. could freeze up and breakdown as the motor will burn up running too long and hard.
If the box doesn't seem to be leaking and you are getting cold air then it would appear that your solution is working- you are cooling your room.
I wouldn't get into the weeds (pun intended) on anything other than if you are cooling or not. U know?

on the real people are saying its not working bc I still have high temps but no no no no where near what they where at but still hot so I am trouble shooting what els I could do

the box its self is the coolest thing in my room so I don't see how that box would b making the air around it hot when it its self is not hot ... my lights are hotter then sin and im not cooling them right
if u put a room full of cold and u have a vent sucking that air out u would need more cold air going in then air being sucked out

The metal case of the a.c., is that hot? By the intake vents.

And the green box and ductwork is not hot, correct?

 

[tinderthumbs]

correct 0 heat best home fix I have ever done on any thing lol hottest spot is on the like where I could not get reflic but that's only 2 2inch x 1 inch strips and that is 77f and only could get that reading when I touched the heat prob to the plastic in then 2 spots

also id like to add n not really a green box any more its full of that super sweet reflect so it more of a green holder of awesomeness

 

[DemonTrich]

I thought your room the ac is in was getting 90*+. If the green box is not hot, nor the metal a.c. case, your good to go. This is only after the units been running (compressor as well). If still not hot, you should be good to go.

 

[tinderthumbs]

the room is getting hot bc that damn LEC 315 sooo good of a light but should rename it super nova

the room was getting in to the 120s before the ac

 

[DemonTrich]

Air cool the light. I run 3x315 in veg and 4x315 in flower. All air cooled. Veg room has no a.c., lung room air only. Never gets above 84*. I have lots of air movement as well. I've always found you need a.c. in flower. Unless you have cold ambient temps or winter air. I've always ran an ac

 

[tinderthumbs]

mine is a open bulb that Is why I cant

 

[DemonTrich]

Are you running vert or open hood, no glass right?

Grab a big 18" oscillating fan or one of those 20" box fans, aim that sucker directly between the bulb and canopy, more so twords the bulb. This helps drop some of the radiant heat from bulbs. I do this in all my rooms.

You can always use an open rated bulb in an air cooled hood of you have that option.
