Thanks Hydro I know I could use a nother fan and will get an extra one on the res also tomorrow. I'll do what I can to get the temps down. Thank god for winter lol

Amen bro. Winter is gonn make this sooo much nicer for me. I thought you might wanna look at this as well. CO2 would really help you situation. Im pretty sure it has been all but proven that co2 helps high res temps. not only would it help your res but your whole enviorment would love it. I have read that if the co2 is around 1500ppm in the air the temps can maintain mid 90's with great success. alot of people might argue and say aother wise but if you check out that video you will see his expirement and i have read it in a few books. Good luck with everything man +rep

Thats the thing...Co2 was going to be bought before a water chiller. I know the temps can be a little higher with Co2. looks like I'm of to the welding supply place today to pick up a tank and regulator.

You need more than just a tank a reg. You need a solenoid, flow meter, etc. You can buy then entire set up for like $130 online. I was pricing them at welding places, and it will cost more than that to buy the pieces seperate and put it together.

And even with Co2, you don't want you temps much higher, if any, than 90degrees, and that is air temps. WIth your res, running C02, and using SubCulture or something, you can get away with like 85degree temps, but I don't suggest any higher than this.

If your temps get up higher than 90degrees, you need to seal up your room and buy an a/c unit. Also, be careful with humidity when you are running Co2. You have to turn off your exhaust fans to run Co2, which is going to cause your temps to get even higher. If they are 90 with the exhaust on, they are going to shoot well over 100degrees very quickly.

I wouldn't suggest getting the Co2. I would suggest spending the money to get your temps down to a workable level. No matter what you do, plants will not perform like they should at 90-100 degrees. Spend the $150 on a nice 700cfm Can Fan, and this will bring your temps down to a decent level.

CO2 is the way to go. 30% - 100% increase in growth.
If want to get a decent CO2 monitor/controller ($300) and selenoid valve $150 plus about $120 tank.

I just borrowed a CO2 monitor from a friend and experimented with
Yeast and Sugar
The air in my room was right around 300ppm with-out any CO2 being added.
1-gallon water
2-pounds of simple sugar (corn sugar or cane sugar)
1/4 tsp. Yeast (preferably Bear Yeast, Lager Yeast) produces more CO2
Mixture lasts about 7 to 10 days.
Produces about 1400ppm at peak. In a 20 Square Foot Area.
Make sure to run the CO2 gas through a bubble counter, and then to your plants. You want about 2 bubbles per-second. Coming from a 1/4 inch tube. Think of the CO2 as a water-Fall falling on your plants. I put the CO2 hose so it's above my Plants.
Costs about 9 dollars per month to run.

I use bubbleponics. The air bubbles in the nute solution cool it down to some degree, just as you would cool some hot coffee by blowing on it.
What ever system you use you could get a fish tank air pump I bought a double air pump at wal-mart $12.00 and air pump hose $2.00. The largest AIR-STONE you can find and put it in your nute solution, The Temp is gonna down probly 4 - 5 Deg. F.

I have 3 6 inch airstones all with thre own pump. I am about to add a 4 foot flex airstone hose type thats suppose to be awsome. Adding irstone has never brought my tank res temps down. AN its bubbling like mad crazy in there. Granting I use HID lighting which is a factor in istelf, but still, airstones are not gonna bring down tank temps IMHO, not enough to make a difference with someone who is high by like 10 degrees or more in tank temps temps.....

On the other hand..having to many airstones is AWSOME for the plant roots and there growth and overall well being, so the more the airstones the better!!!! In DWC systems and Bubblers its almost a must to have many airstones if you wants to grow fast and have aswome healthy roots. That and water temp in the tank is key....mixing thr nutes is a no brainer for the most part.

Are you air pumps in the grow room too? This will make them pump the same temp air as the room into your res, and this will not let it cool.

If you have them outside the grow space, preferably in a totally different room, the pumps will be pulling in cooler air and this will cool your res. The air has to come from some where, and if its from a cold place, the air going in will be cold.

I never though of that, could be why my Res. temp is a little cooler than the grow room air temp. Makes perfect sense. :hump:

how long can i run my air lines from my pump to my res without loosing pressure? thanks by the way
A long way.

If you put aior in the tube
it has to come out wherever it can.

How long of a hose does your garage use to fill your tires ?

I wouldnt go more than 6 t 7 ft with air hose unless you got some kinda comercial grade airpump. After 6 to 7 ft you start to loose spme psi I assure you. I have tested this part extensivly and tried about every combo possible including a "air rail", Ive tried to tee them off and cheat htat way also. Didnt get near as much air.

You want the air tubes going to airstones to be as short as possible (keep maint. in mind when decideing lenght of air hose from pump to airstone).

I use 1 standard air pump to each airstone which is 6 inches long each. I have a total of 4 air pumps and 4 airstones which covers each net pot giving it PLENTY of nice bubbly air/water(6 pot planter).

This works very well though if I did it over again I would have tried one of the 70 to 80 dollar 4 port comercial air pumps..either way as long as you get he PSI you need and amount of airstones to make sure each plant is getting PLENTY of air bubbles, then your covered!

Peace!
 
Keeping the res cool:

in my water res I use a seperate pump that is hooked up to an old transmission cooler that has 2 computer fans tiewraped to it.
