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?

Put a fan blowing on the RES., or put some reflective Mylar to covet the res so it doesn't attract light/heat

water chiller.. no exceptions

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

lol sorry and put a pump on it of course

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 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 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 cool your temp way down 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 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 . this way . A ac cannot do all that .This would be much cheaper and as well on your elect bill

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 this would have 3 function . this way . what do you think ?I do know this works very well , at least for me
