DWC water temperature

  1. I have read a few different things about what people believe is the best water temperature in an rdwc setup. The range seems to be from 60-68 degrees. If I can keep it at 60 is this best? Low 60's? Mid? High? Obviously this is assuming I can get it this cold, just curious what the plants like best

    66 is perfect imo
     
    a mild fluctuation is expected, just don't let it get too high to avoid a lack in DO
     
    or too low, which will shock your plants and stunt
     
  3. Above 70 you run risk of bacteria growth which can lead to root rot, and you have less dissolvable oxygen available, below 60 start to slow down photosynthesis and run risk of shock.

  4. I run a homemade chiller from an ice chest that I change out 4 to 5 frozen 2litter bottles 3 to 4 times a day. most the time keeps it in the mid 60s running to 12 buckets. If I dont get to it for a while it does climb into the mid to high 70s. I had the ice chest and the pump, the pump is about $10 online, some copper pipe, hose clamps, grommets,  and irrigation line. Was about $35 or so, pics in my growlog.
