They do make 400-1000 BTU thermoelectric air conditioners. These cost a bit, but are used in wine coolers and other temperature sensitive situations.
How much is a refrigerator cooling unit? Is that practical for a 5 by 5 by 3 foot grow tank?
Nick, we have those in the big soda cooler at work. I'd imagine they are PRETTY $$$

They are $$$. I asked one of the pop(soda, to you East Coast people, lol) companies, and for a used condenser, they wanted about $250. I know nothing about electronics or refridgeration, but you can get a dorm room fridge for under $100. I got a six pack fridge at Toys R Us for $20. I am not sure if it will work, but I will find out.
peltier junctions? evaporative cooling? Enlighten me please.
Definition of a peltier junction: Peltier Junction - When electrical current is applied to a thermocouple a temperature difference is created, with one side of the thermocouple being hotter than room temperature and the other being cooler. Peltier Junctions (Peltiers for short) can be used to cool microprocessors, where the cool side contacts the microprocessor and the hot side contacts a heatsink. Peltier Junctions are rated in watts. If you do not use the appropriate wattage a Peltier Junction will be ineffective.
Basically a peltier junction is a heat pump, which pumps heat away from the body, hence reducing the temp. Quite a sophisticated piece of equipment.
Just do a search on it and it will come up a ton of info and companies selling it.
Evaporative cooling is when water takes heat away from a body to evaporate, thus reducing the amount of heat in the body and hence the temperature.

Hope that helps,
Couldn't you just rip the cooling units out of a fridge and hook it up to a thermostat?
Then throw in one of those foggers to keep it a bit more humid? (cooling element will most likely bind humidity, thus lowering the relative hum...)

Hey guys thanks heaps i think ill just have to experiment with all the different cooling methods such as ice etc.

Do not want others to know what you have done? You should not have done it in the first place.
Can you elaborate more on the "six pack fridge" you mentioned getting at Toys R Us? Is there a brand name, and how much did the unit cost? This sounds like it has potential.

Yeah...that six-pack thing sounds interesting for cooling a small grow chamber. Hmmmmm... wonder if they have them on eBay...
