It's getting hot!!! How can I build a light damper for my window ac unit?

Cool thx KNowm .I think I'll do that.
I wanted to runit threw the light so I could get it closer to the plants though.So I am going to run it thru the light. But between that and the ac inthe window I'll be fine. I'm also going to switch to lights on at night .

The idea of pushing air through a hood is simple physics.

When you pull the air through the hood the fan will work harder and still may not get up to speed. The backpressure of the motor working hard will also generate HEAT. Do you push air through the AC in your house or pull it through. You push the air across the coils not pull it across.

By having the blower outside and pushing air through the hoods the motor spins at full RPM's and has no back pressure to start with. Pushing the air will create a small amount of backpressure but with the motor spinning at full RPM there is no noticeable problems.

You can install it either way but my way the motor will last longer and produce less heat.

It's up to you.

I see now.

Just thought I would add my 2 cents.

When we used window units (back when I worked nights) I used to use Duct tape around it. Especially with the vinyl windows.... it is a much easier clean up. 2 layers keeps all light out... which is important when you sleep through the day as well...lol

Cool, thx Sticky!
I'll do that. The unit came with these foam things to put imbetween the window and AC unit. But I don't think it's enough.
I'll add a couple layers of duct tape. Plus I'm going to inselate the window that has to stay open.
I'm going to cut a piece of 1/2 inch plywood. And bolt it on the inside and outside of the window. And put inselation inbetween the wood.And ac will come threw the wood.
I'm also going to hang a shade thing above the window to keep it in the shade.:thumbsup:
As far as the light vent goes. I have to do it with a fan that sucks instead of blows because I only have one hole in the wall and my partner doesn't want to put more holes in the wall.
When I move,I'll do it the right way.By then I will have bought my own vented hood.I already have the ballast and socket.
Anyone got a vented hood here in Cali that they want to sell?
Something with 2 4 inch holes. And can be hooked up to SUnlight supply ballast and socket.
