Cab is too HOT - how can I cool it? No ice/cooltube.

Okay, so right now it is about 85-90 degrees in my closet grow room setup (which is a PVC shell covered in panda film). I have 3 fans running in it (2 x 120mm computer fans and 1 5'' clip on fan). The only light currently in there is a 150w HPS with a batwing reflector.

So I am just wondering does anyone have any innovative ideas on how to cool this space? I would most likely have trouble creating a cool tube for my setup, and I don't even know if that would help since my closet is basically a closed air system, so I'm thinking I have to bring in some sort of coolant to this setup. I am unable to swap out 2L bottles filled with Ice since I do not have the extra room in my freezer for all that water, so I really have no clue what to do.

I was originally looking at purchasing a really tiny mini fridge and just opening it up and placing it in there, but I am unsure how efficient/effective that would be.

So if anyone has any ideas on what would work just let me know, since my last grow resulted in fluffy buds due to the heat issue.

Thanks!

heat sucks! but what u would need to do is open the door more often.by doin this u get more fresh air and it should bring your temp down 5 or so degrees but long term my dude u need to get at least a 4 inch inline fan to suck out more of the heat/ stagnant air. they have some cheap efficiatant ones on htgsupply.com for like 20 30 bucks. do u have clip or oscillating fans in the growroom? if not get 2 of those to move the air around which will also help with the heat

Yeah, I have a 5'' clip on fan located in the cab blowing air on the plants, and I can't really leave the door open since it is a stealth grow. So if anyone knows of something that you can plug in and it will cool an area let me know...like a space heater, but a space cooler, haha.

Wish they made something like that...

anyone have any suggestions?

4" Inline is the way to go!...treat the source not symptoms!..ive had the same heat issues in a similar grow room....without cooling your HID light your room will continue to be hot....any cooling unit will make your growspace cooler but will be a pain with unsatisfactory results..on my previsous experience ive attached an ac unit...they drain a lot of power! and the unit itself will emit more heat....cool tubes are expensive but you can make an air cooled reflector by making a box with one side exposed, where you will cover with glass your batwing placed inside the box for reflection of light. hot light= hot room...simple as that..good luck

Anyone care to elaborate on this idea? Basically a cube/box with one side made out of glass? Seems like a ghetto rigged cooltube to me, but maybe I am just interpreting it wrong...
