Liquid cooled lights, anyone got one?

like the title says, im thinking of investing in a couple of these, i know they are expensive, but you really cant put a price on your plants health, or could you?

Not sure if they are truly worth it. They look like more work then anything else. If you run two you need a 100 gallon resevoir and a tank chiller. That is a lot of wasted space if you ask me. Hey but to each their own.

Yeah, im not hurting for space, i would just like to know that if i spend the money, will it indeed eliminate the need for all the ventilation im running.

I know plants need good air flow, but if i can get rid of all the fans, i can run a c02 setup since the turbulence wont wash the air of co2, get what im saying?

I run CO2. The real trick to running it is you need a good controller with a co2 ppm metering system. You also need to completely seal your grow. I use magnetc dampers on all my fans and I even got the nice gasket sealed hoods to make sure I do not waste anything. I am running a 50 lb tank in a roughly 350 cubic foot area. I am only about 1/3 of the way through the tank and only have 2 weeks left in a 9 week flower cycle. I run a 737 cfm can fan to cool my lights and I use the heat from them to heat my house during the light cycle. I use a 6 in. intake and exhaust and my room only vents about every two hours, with the temps set at 85. I take fresh air in from outside and vent my exhuast outside as well.

right now, my problem is that im using a 500cfm fan to exhaust my flowering chamber which only totals about 112 cubic feet, my air is exchanged once every like 10 seconds, lol, overkill i know, but i did it like that so the turbulence would come from the ground up, keeping the plants cool and with plenty of fresh co2, when i figure how to keep my lights temps cooler, i can bump down to a much smaller inline fan to cool my lights and run co2 when the air exchange isnt so intense, you get what im saying?

You need a higher cfm fan cooling your lights. You need to pull air from outside the grow, preferably from the coolest place in the house and vent it away from the room your grow is in. If you are cooling 2 1000w lights with anything less then 700 cfms you are wasting your time. Also I do not suggest pulling in an inline. Buy a 8x6x6 Duct Y adapter you can find them on ebay or at your local heating and cooling supply house (Lowe's or Home Depot will not have em). You should have you filter on your exhaust and be venting outside or into the attic. You can pull air straight in from outside but I recommend a magnetic damper to close and open upon activation. How big is you space? That is really the question that needs to be addressed. If the space is inadequate then I see no use in running CO2.

Water cooling could be quite a problem.

First, I don't see any way in which the water wouldn't be in contact with the lamp terminals, so the water would need to be de-ionised or it would arc over and explode the whole mess with steam. You'd need to periodically check the water conductance and replace when necessary. A total pain! Otherwise maybe there are special insulated gasket-sealed lampholders available, but, the cost!

Secondly, if the water flow failed for any reason with the lamp on, the lamp would boil the water in the cooling jacket and it would sooner or later explode throwing steam and glass everywhere. Great...

Somehow I can't see this idea going anywhere.

Buddyluv has the right ideas.
