The reason I asked about water is there is a lot more in city water than what people think, which in my mind could lead to problems. Coming from an aquarium background, many tap waters will test around 100-300 TDS or total dissolved solids, and by using RO water about 90-95% of those get removed (<10 TDS after RO ideally), and the deionized or DI water should be pure H2O at 0 TDS. Different bottled waters are usually RO or DI if you read the fine print. Distilled should be the same as DI but how you get there is different.
Wondering if there would be less mold issues with a more pure water. Later on though probably better to use city water because of the added nutrients.
