good luck with that. you'd need one about 4x6 and good luck finding a fan for that. not trying to be a dick but i been doing the water cooling thing a while and that is never gonna work. bare bulb, Co2, etc.... i had to run 2 ice box heat exchangers in a 64sq.ft. tent with a res temp of 62 degrees just to kip that thing cool.

Scooby is kinda right. With your heat gain you would need a large coil but depending on incoming water temp, btu output of CO2, dehumidifier output, etc. First off duct your lights to exhaust. If your water temp from well is 45F you can get a coil that will do it but it is 48"x24" and you still need to duct it and add blower, water usage would be a concern as well. Its still a viable option if you want this setup for a long term solution. It would also dehumidiy so may not need the stand alone's. Did I mention Ductless A/C lol, thier pretty energy effecient now! Its impossible to find exact model without more info but lots of stuff on Google to help. Lights alone produce 12000 btu's (well real close).

They do that in Canada where the water is cold and for the most part plenitiful. If I'm not mistaken they typically use a water cooled air handler.
So to do a sealed room wth 3k correctly, your going to have to have some budjet for equipment.
You'd have to look long and hard to find someone who setup a sealed room for less than I did! I picked up a used LG window AC 18000btu for 150.00 on craigslist. I use a tankless hot water heater for co2 100 bucks ebay and have purchased most of my ballasts used on CL as well.
Even on the cheap it still ads up, but if you can't provide the environment 100% of the time you might be better off seeking a more cost effective solution.

Very rarely do we see water cooled coils in my area. Toronto uses deep lake water (Lake Ontario) for cooling in core downtown buildings. Most are conventional systems. Ductless units are very popular here as well. Most ductless units are now heat pumps and also have low ambient cooling capabilities. I am probably going to use a water cooled coil in my res but my heat load is a quarter of ops if not less. Also I have a deep lake to draw water from. If the reason for water is to save money I'm not sure it would. Blower motor for required air would draw 6-7 amps. The water pump would draw 8-10 amps. And run frequency would be more than ductless. You'd have to run the numbers to see. But hey you could hang a car rad in the air and run 12 volts to the fan motor, run cold water through and see what happens.......lol. Really neat to see if it works at all lol.
Tanks all to reply my post i will go with more realistic room setup 2 x 860w cmh bare bulb for flower and 1x400w cmh bulb for veg magnetic ballast out off the room, i have a c.a.p propane co2 generator with an 2 feet aluminiun heat sheild tube i have diy installed on co2 generator with 4 inch fan blowing air frow outside the room to outsite the room to help reduce co2 generator heat and a desumidificator in my room,i want to try radiator with fan with water throw it but if not work.. I will try chiller or split unit, if i chose split unit i want one cheap with diy installation with no hvac guy..i am scared to buy china junk that dont last i like the aura 24000bth but no idea if junk or not ,i like the idea off a chiller i can move outside in summer and inside winter to help heat my house,on ebay i have 2 hp chiller ln series aquarium chiller for 1100$ the prize are more on my budjet than chillking chiller i run bare bulb with just 1 or more heat exanger what is your opinion on the ln series 2hp chiller good product or not do the job or not..

Pretty much all ductless are from china or korea. Never heard of aura! As for chiller again there's lots of sizing charts. It depends on res size, delta t, etc. if your planning on doing ductless you'll need some stuff like nitrogen, guages, and vacume pump. Best to find a hvac buddy lol. Let me know how rad works, i'm a fellow DIY'er!!

Ok so i just looked at the aura. It has precharged line sets so yes its plug and play. Its not very efficient at 13 seer but not a huge deal. The buggest issue I see is cooling can only be done when outdoor temp above either 15 or 18c, it says both lol. Most units i deal with (Fujitsu, LG, Samsung) have low ambient cooling, -15c.
