Whats a good economic air chiller?

Hello again community! I'm still trying to figure out how to cool my mid-sized tent. I've been looking at a lot of ratios and calculations for cfm, looked at air cooled hoods, water cooled hoods, and finally landed on possibly investing in a quality but economical and easy to install stand alone cooler. Anyone with information on this subject would really help a lot.

No HVAC specialist wanted around my grow, don't want to pay an arm and a leg to purchase or to run it and (of course) I want it to cool my tent from 96'F to the optimum 76'F daylight running temp.

I have a 6" can fan and filter and a 230 cfm booster fan. The light albeit is probably my problem its a 150w HPS enclosed ballast with no cooling ports. I know, I know you probably are saying "a 150w!? WTF?" But I plan on upgrading that soon but in the mean time and for the coming spring/summer I think I can make due with that and focus on heat. I'm only going to attempt to flower 1 plant under it, so don't hate unless you have something useful to contribute. Thanks in advance. Greggos

they money your going to sink into a chiller you could just buy a 1000w dimmable light kit with a cool tube and you will lower your heat and get a better light for future expansion.

IMO start with the cooltube. even if you will add cooler, you need it to perform at its max, a cooltube is a passive system that helps in lowering temps, that way you will use a smaller cooler or the same cooler will operate better and consume less electric

I'm now looking at buying a dehumidifier either with a chiller/AC or one that I can retrofit into one. Have any info on these? Difficulty? Budget? Anything would be helpful, this thread is sorta dead...

I have been looking for a single-room AC unit as well to help with grow room temps. I found this on Home Depot's website.

It's a bit over $200, but its a one time purchase and much better than those air coolers that use water evaporation to cool the air.
