How to remove heat without fans?

Looking for a way to move heat, without having to use an exhaust/intake fan? The reason being the closet, I am growing in, isn't mine, so I can't really modify it.

The temperature is hitting 92-5F, I have a fan to circulate air, and when I open the door it drops to 86. I realise that this isn't too hot, but it would be useful to lower temperature.

Any ideas?

And on a random note, to get the chlorine outta water you leave it for 24hours +, with or without the cap on?

one word, " Impossible " , unless you know an ingenious way to use cold water !!

how bout a window ac unit go buy a cheap door and borrow a sawzall

you still need fresh co2, there has to be an air exchange unless you are providing another method of co2.

got a homemade co2 bottle thing with the yeast and sugar, you know the one, so leaving the door open looks like the best option then!

Take the door off and put up plastic.

would have to be black plastic for lights off.

Those heavy duty garbage bags are great.

Just buy a cheap door. As long as you don't need to explain why there is a fan mounted on your door to anyone, it should solve your problems.

If you can't trim some of the bottom of the existing door off you could go buy a door and cut a vent in it or look around some job sites for a door they are trashing.

I put ice in jugs infront a fan on the floor blowing the cold air in the room with a taller fan blowing the hot air out of the room from the top and this seems to work fine during the heat waves
