I'm not quite sure about the logistics of using deionized water, however; I was talking to the dude at my local grow store and he told me never to use distilled water in my hydro system....he didnt really elaborate so idk if he was just blowing smoke or what

tap water here is about 7.0, so its not that bad, maybe just use the tap and pH it down would be ok?

By the time you figure in some nutes, you may not have to pH down at all!

I just moved and the new water, here, is "Alkaline Hell"!!! It takes 55 drops of "pH Down" to neutalize 2 litres @ 6.8. I had to switch to bottled water for the "short run". I would kill for tap water @ pH-7! Go ahead and use your treated tap water, just bubble it for a couple of days.

Oh yea, about the other question! Proper, "Distilled Water", is just normal water that has been boiled away and the pure steam is then condensed to produce distilled water (pure H2O). RO water is normal water that has been very well filtered (about 1/2 micron, or less), using the "Reverse Osmosis" process. Deionized water is a little more complicated - I'll let someone else explain that!

yeah i was thinking that too, thanks. im in the bay area and we have pretty good water. but we are currently on water restrcition so i might have to end up buying the water anyways... so if i do have to buy water is it ok to get that distilled stuff? i hear some people say you shouldnt use it and some people say no problem. if i do end up using distilled, do i have to replace the lost minerals with cal-mag or some shit? thanks gain!

It takes up to 6 gallons of water to make one of RO...

The best units can get away with 3 gallons of waste to one gallon of RO.

Water restrictions suck ass
