You can use tap water but leave it in an open container for at least 24 hrs to evaporate the clorine. Be sure to test the PH of the water before using. Some use bottled drinking water or distilled water. Other have R/O (reverse osmosis) filtration systems. I am using PH'd tap water on mine.

Reverse Osmosis treated water is one of the best water sources for indoor gardening. The process strips almost all impurities from the water. I don't think anything beats rain water (as long as its not acid rain).

Is it bad to give the plants water with no minerals in it, such as reverse osmosis water? I heard it was

You may have to add the minerals back in via nutes.

Cal/Mag (calcium and magnesium) are the ones that i see most people adding to RO water. I'd think that this is especially important in hydro because the plants are totally dependent on the grower for nutrients. Unlike soil, if u slip the soil may have just what ur plant's been missing provided there's no lockout or nute toxicity. Never used RO water, only distilled and filtered. To answer ur question, yes u can use tap water. Some cities/counties water is better treated than others but it'll work until u can do better.

Don't use water from a water softener! I learned that the hard way. I've used tap water from several different wells and have had no problems. I've also used city tap water in a couple different cities...again, no problems using it as long as it sits a while.

You should check with your utilities company to see how they treat their water. There has been a shift from Chlorine to Chloromine. Chloromines will not evaporate out of your water and not all RO systems can successfully filter them out. Here is a good read from the EPA on them:

Chloramines in Drinking Water | Stage 2 Basic Information | Microbials and Disinfection Byproducts (MDBP) | Safewater | Water | US EPA

Lotsa rain here and I collect it for my babes; other than that I let the tap sit out or use well water when it's safe to bring em outdoors.
