So RIU whats your method of cooling your buckets? my room hits something like 80 degrees and as such my resivoir is showing the same temperature! Obviously 80 is way tooooooooo high for dwc, so what do you recommend RIU to chill my buckets? I bought some water bottles, standard 20 oz and plan on freezing and placing in resivor, but how many do you think ill need for a 5 gallon bucket to keep it cool while 12/12 is on?
