Aeroponic Reservoir Temp Climb

Hey Guys,
Having problems with my reservoir temp. Using a 400 GPH ecopump, 1/2 pvc. I don't have a timer on it yet, but it will be here in a few days. Hopefully this will help, but I'm not sure. Any ideas as to a cheap solution to keep the temp down?

I've got air duct tape on the top to reflect the light. There's also a fan on the reservoir.

As far as a chiller goes,... man they're expensive. Any model you would recommend?

So I figured out a cheap solution.
I got a larger reservoir, went from 10gal to a 22gal reservoir. I freeze 3 1gal milk jugs full of water, I swap them out of the reservoir twice a day. This keeps the reservoir temp at 65 to 70deg. No $500 water cooler needed.

If you don't mind taking up freezer space. Freeze 2 gallons of water. Pull one out in the morning and put it in the rez. Then switch in the afternoon.

Edit @JMahone You beat me to it!

Water temps were the bane of my existence my first try with DWC :( I wish I could give you some advice, but even frozen water bottles didnt save me lol. For now im running soil, but when I do give hydro another shot ill probably try a flood and drain table. That, or I will wait until I can buy a water chiller. You can make your own from videos on youtube, but they are not very aesthetically pleasing lol.

You could get a apartment mini frig around 80 $ run a copper tubing Or I seen garden hose drill hole for the flow the in and out, take out the freezer part set it on high . Then put a valve on the exit line to control the flow help better on temp. thats it :bigjoint:

Yeah, after I get a few harvests under my belt I'll have more cash. I've already spent about $2000. I still have another light to buy. Trying for a perpetual grow room.

I like this idea. You can get a coiled line to make sure it takes longer to run through the fridge. Not sure how economical it would be. But cool idea.

If you have a very large res to get it even cooler you just add frozen 5 gal or what ever that would fit your mini frig and your coil around it . the cost is only the mini frig running is very little. and you can use it for more that 1 purpose :p just add a small water res that fit inside the frig at lest 5 gal add a small fish pump run a recir line from small res to a hot box or a car heater core put it next to the intake on your hood light 8-) so now as your fan pulls the air through the hood light it goes the the hot box or car heater core its cheaper that a hot box :bigjoint:cool your temp way down :weed: and if you want even colder just add another heater core with a fan with a temp controller have it run the fan as a air conditioner ;)

Or just buy an a/c, lol

lol :p well this would be a water cooler for the ras / and a hood cooler for next to your light and a area cooler all just paying 80 $for the mini frig a small fan and a smal heater core :bigjoint: . this way . A ac cannot do all that .This would be much cheaper and as well on your elect bill :cool:

Well not sure about you but I pay $0.32/ KWH so my bill is high enough. Plus it'll be running 24/7...

Let's say they are 10 amps and you plug it into 120... That is:

amps x volts = watts
10 x 120 = 1200 watts

watts/ 1000 = KW
1200/ 1000 = 1.2 KW

We will be using it for 24/7 - let's say 30 days
(KW x hours) x days = Total KWH per Month
(1.2 x 24) x 30 = 864 per Month

My cost (which the worst I have seen on RIU as far as KWH cost) for one month would be:
KWH Cost x KWH Used = Total Monthly bill
$0.32 x 864 = $276.48

.....<Hold on here cause I think my math off>.... I am assuming that the mini fridge does not use 10 amps for 24/7 but if it did it would quite expensive. Most a/c that are built in run off of 220 which, in short, cuts the amps in half. Running my a/c during the day jumps the bill by $100 bucks give or take $50.

I see but for the cost it is only helping for temp only and the compressor in much smaller in a mini frig :bigjoint:this would have 3 function . this way . what do you think ?I do know this works very well , at least for me :blsmoke:
