I am finally getting ready to build a drip system for my coco set-up (drip to waste) and am wondering if I absolutely need a res chiller. I will be using two 44 gallon res's. Temps are about 80 degrees ( i run co2). I am worried about the higher temps leading to funky water and possibly leading to root rot or other problems in the coco. I am guessing I will need to refill the res's with fresh water and nutes every 2-3 days because they are so small. What do you think, any suggestions or experience?
