Hey there. I have some general questions and didn't want to start a thread about it. I'm building a DWC setup with 12-15 5 gallon buckets. I'm hoping to get some advice on what kind of air pump or pumps I would want to use with that many buckets. I'm allready commited to doing DWC and not RDWC. Also, I haven't had an issue with it in the past but the DWC I've run in the past weren't as large as this one, I'm worried that a heavy duty air pump will heat up the buckets. Is this common? The buckets will be fed by a larger resevoir so they are not entirely self contained but I don't imagine there is much if any water circulation other than what gets replenished when the plants absorb. Thanks in advance for the help!
