HI Mad
I'm using 250 litres dwc set up.
I had a problem with the res temp. I noticed the girls weren't liking it to much an I had root issues, turning slighty brownish which I presumed would develop in rot. I used various methods to pull the temp done and was successful in installing a water chiller and I now still change frozen water bottles twice during lights on. Im currently in 12/12.
While I was in 18/6 the res temp was sitting around 26C with changing frozen bottles 4 times. Trying to maintain a steady temp of 18C.
Now I have no problem with the res temp floating around 18/19C using a water chiller and frozen bottles.
I also have a aircon unit helping with the room temp. Again this is set to the 18C mark.


I hope thats of some help to you although I dont claim to know much as this is my first DWC. But Im pleased so far with my girls growth.

Good Luck

The secret to dwc is a constant Rez temp of 68 degrees. Do that first and the rest is gravy.

constant temps are definatly a plus,but,keeping root zone under 72 deg. is much more important imo.Frozen water bottles work well if you don't have a chiller. I live in NY and grow in my basement,floors are around 55 deg so I don't have the problem. steady temps at 67-68 deg. without a chiller.But yea if your temps are above 72 use frozen bottles,or even frozen nute solutionto cool your water.

Thanks for the info, im going to put more bottles in to lower the temp. im in a 4 gallon DWC site my plants havent had any issues yet to the water temp just want to lower it since im in flowering phase also.

im down south, wish i was back in NY wouldnt have the heat problems lol. central AC keeps temps around 82 at max so not to bad.
