He has back ups for back ups.
lights that are cooled?? HOW.........

I am building the Iceboxes for about $50 a piece and have a source for a 1/2 HP chiller for $375 all I need is a nice inline pump a reservoir, some hoses and clamps, and I have pretty much the same system for a hell of lot less.

Well let me know the specs on how your building em'.....and where I can get a 1/2hp chiller for that price....I like that idea of water cooling my lights, although I will only be using 1 maybe 2 1000hps

Nice!!!!!!

It is in a way. The difference is that the chiller is cooling multiple things at once, just not the air for the lights and it's more energy efficient that AC for the same cooling effect.

I have a thread on it "DIY Icebox" and here is the link for the chiller. http://cgi.ebay.com/NEW-1-2-HP-CHILLER-REEF-FISH-TANK-AQUARIUM_W0QQitemZ150368769310QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2302ad551e&_trksid=p3286.c0.m14 It's not really water cooling the light, it's water cooling the air being forced through the trans cooler.Well let me know the specs on how your building em'.....and where I can get a 1/2hp chiller for that price....I like that idea of water cooling my lights, although I will only be using 1 maybe 2 1000hps

basicly how an A/C works,,,right

Yes the only difference is with a chiller it is maintaining the temp of the water in you reservoir which is easier than an ac maintaining air temp and it is directing the cooling right at the biggest source of heat in your room. That pros of the icebox chiller set up are not that great, for me it is an issue of space, portable ac takes up to much space and is noisy. As far as cost it is not going to be much more than an ac unit would be.

One more thing sorry. If you are using a portable AC unit and keeping it in the grow room it is producing alot of heat that it has to cool also. When using a chiller setup the compressor part of it that gets hot, is outside the grow room so there is a benefit there also.

if air is being forced through cooled coils ITS A/C
Window and Split-system AC Units
A window air conditioner unit implements a complete air conditioner in a small space. The units are made small enough to fit into a standard window frame. You close the window down on the unit, plug it in and turn it on to get cool air. If you take the cover off of an unplugged window unit, you'll find that it contains:
this split system is what the guy in the video is basicly useing
the water is cooled out side the house then pumped to coils in the forced air unit
Chilled-water and Cooling-tower AC Units
In a chilled-water system, the entire air conditioner lives on the roof or behind the building. It cools water to between 40 and 45 degrees Fahrenheit (4.4 and 7.2 degrees Celsius). This chilled water is then piped throughout the building and connected to air handlers as needed. There's no practical limit to the length of a chilled-water pipe if it's well-insulated.
You can see in this diagram that the air conditioner (on the left) is completely standard. The heat exchanger lets the cold Freon chill the water that runs throughout the building.
In all of the systems described earlier, air is used to dissipate the heat from the outside coil. In large systems, the efficiency can be improved significantly by using a cooling tower. The cooling tower creates a stream of lower-temperature water. This water runs through a heat exchanger and cools the hot coils of the air conditioner unit. It costs more to buy the system initially, but the energy savings can be significant over time (especially in areas with low humidity), so the system pays for itself fairly quickly.

- Cooling towers come in all shapes and sizes. They all work on the same principle:
- A cooling tower blows air through a stream of water so that some of the water evaporates.
- Generally, the water trickles through a thick sheet of open plastic mesh.
- Air blows through the mesh at right angles to the water flow.
- The evaporation cools the stream of water.
- Because some of the water is lost to evaporation, the cooling tower constantly adds water to the system to make up the difference.
