I've searched, read, and tried what I have found online and can't seem to find my way to success, sadly.
I have 4 gallon nutrient solution tubs (2) that I need to chill somehow. Each tub is 10 gallons, but I only use 4 gallons of solution. I have a 16oz frozen bottle in each and can't stay under 79.5 even with mylar lying on top of the tub. Would painting the lids white help at all? The mylar is a bit cumbersome to be quite honest. Flat white spray paint is a whole lot easier...but will it help?
I have a box fan pulling air out of the room and a fairly powerful fan blowing on the hood from a short distance that also moves the plants a good amount. I don't have a air cooled hood nor do I want to go that route, I just need to keep a constant 75 or less.
If when using bottles, the roots come in contact with the ice cold bottles...will it damage the root system of the plant? I'd think it would, but i'm thinking there is some sort of physics that takes place and makes the answer no. I can't put 5 bottles in each physically, or I would. I don't want to buy new tubs, I just did that for these tubs.
I have seen the igloo chiller, but I don't run a RDWC, just a basic DWC with rubbermaid tubs. Id like to think someone has figured a solution to drop temps a few degrees at the least. If I could just get mid 70's i'd be happy.
