Small cheap portable ac unit? For closet grow.

I have the option to either run a small tubing 1-2" in diameter from my window ac to my closet or buy a small portable ac to cool it down. Once I vent my hood it should cool it down as well but in my test run it was still low 80's in temp so I need to bring cool air in somehow. Have 400w hps and will be running another 130ish watts of t8 for clones in the near future and don't want to drop a ton of cash. Any suggestions?

You could run c02 as an option. They will tolerate higher temps with higher c02 ppms.

you will still have to run the exhaust ducting from the portable ac to your window to exhaust. They come with a window plate that has a hole in it for the ducting. Having an ac in your window will you be able to rig it to exhaust the hot air? You won't find them cheap. They are pricey no matter where you shop. The cheapest one I could find was just under $200. What I do is take my closet door off, cut black plastic sheeting to fit over the opening and fasten with velcro stickies. One 6 inch hole near the top to send ducting out for exhaust with a 6" inline duct fan. One 6 inch hole near the bottom to draw in cool are with another 6" inline duct fan. I use black duct tape around the gaps of the hole for light leaks. I keep an oscilating fan in the closet with another fan blowing over the canopy cooling the heat down from the light. I keep my room as cold as possible so the air coming in through the intake is able to keep the closet below 80F. During lights out I have another piece of plastic sheeting that I run at an angle from the start of the opening of the closet to the wall to the left of the closet....double dark This keeps it totally light proof while still being able to drop the temps at night by 5-10F. I just have to adjust the intake fan on the room side of the makeshift tent to draw in the coolest air when the lights go out.

Craigslist or garage sales...I saw one at a sale a couple days ago $50.

I thought about taking the door off as I keep it open now anyways I get the temps at 75-80 depending on how high the window ac is fired up/how cold my room is. I'm on the hunt to find tubing small or flexible enough to run under my door since there is bout a 1.5" gap this would allow me to bring cold air in and continue to vent the hot air into the attic.

I have used computer 120mm fans as well for ductin small areas. You can take any power supply and bridge the green and a black wire on the motherboard conection to turn it on. 120mm fans can push 60-80 cfms.
