Non-potable water. Safe for cannabis growing?

@theuk420show. Taps aren't broken, but it's an old building and sediment (or something) seems to get in the tap water. I've been using bottled water. A bit expensive but we'll work on the water issue later. I needed to learn how to grow something first. Still haven't done my first harvest yet. But I have this new humidifier now and I was wondering if the water I throw out every morning was good for plants for any reason.. Looks like it might be... It might not be.

You could if you wanted but I would stick an EC meter in there first the check the amount of contanimants in the water. Are your taps broken ? leave a large bucket outside rain water is very good for plants but you need to ph and ec the water just like any other feed. Unless your using our nutrients anyway ;) ph balanced boo yah

I didn’t know this was even an issue! I do it all the time! I do find it to be around 6ph—- and after nutrients I have to add ph up—- versus tap water.
