Dwc cooling

Hey guys. This is my first dwc. I got 2 Humboldt headbands 2 weeks old in dwc. They are under a t5 4ft 8 bulb. 4 red and 4 blue. I'm running ph 5.6 and currently at 340ppm. I knowticed this morning that my res temps are like 78. I'm using gh flora 3 part and cal mag+ with distilled water and hydrogen peroxide. Not having any issues with smells or cloudiness or anything but I'd think that these should be a bit larger. I need to find a way to keep my res temps cool. My concerns are that a res chiller will blow my circuit because I have 1000w hps in my flower room with a humidifier and the three fans in the two rooms combined. My veg room and flower room are on the same breaker I think. I'm not an electrician at all but in the beginning the hos would blow the breaker until I plugged it into a Serge bar. Now I'm not having issues however I'm afraid a res chiller will be too much. Any ideas guys?

Run another circuit.

You could choose to run an extension cord and run the chiller off another circuit in the home. Or just have another dedicated circuit ran.

I would drop to a 600 watt light for that number of plants anyway. Do what it takes to run a chiller.

Right now I am building a water chiller from my own parts. I'm gonna share that stuff soon. Or, if you PM me, I can show you what you can do for well under $100 to cool your water temps. By the way, I would say that 78F is not so bad. It's when you go over 80 degrees that you're going to run into a problem with stuff growing in your reservoir that you don't want there. My last grow during the summer, I was putting those plastic things you fill with water and then freeze in your freezer into my reservoir, and I had very healthy roots. I realize that water chillers cost a lot of money, so I'm building one now that anyone here could duplicate.

if you can somehow put the air pump somewhere that it will suck in cooler air it may help. also you could try insulating the buckets with bubblewrap and do the ice pack thing

what about filling the tub with water and controlling that with ice or something?? I bet the plants would love the humidity but i would worry about algae from the lights.
