yes you can. why do you want to?
its neutral (7) but since there is nothing in it to buffer its pH will be very unstable. left to sit by itself it reacts with co2 in the air and pH becomes slightly acidic.
distilled water also doesn't have any calcium, magnesium, iron, and the other goodies that are in most tap water.
so if you do use distilled water, you might consider adding a little cal-mag in addition to whatever other nutrient solution you're using.
if your tap water is below .4 EC or ~200ppm you might wanna just use that.

Ill agree to all but the cal/mag, whats in water isnt a nutrient like our calmag and ours dosent act as buffer in soil.
Easier to not add calmag to water

So if using distilled water where does the plant's needed calcium come from?Ill agree to all but the cal/mag, whats in water isnt a nutrient like our calmag and ours dosent act as buffer in soil.

Don’t use plain distilled water to water your plants. It’s pH isn’t going to be neutral like you think. Distilled water absorbs CO2 and makes the water more acidic. The pH on distilled water will normally stabilize at ~5.8 if exposed to air. I normally mix it 2:1 with my local spring water which has a pH of around 8. That’ll get you in an ideal range. You may have to tweak the mixture depending on the pH of the other water source.

Mr Green here is quite correct.
I will not use any distilled, De ionized or lab grade "pure" water's.
RO is great. Start at 0 and add from there. It is true for hydro, that you should add a Ca/Mg source (as a buffer and Ca/mMg source) to RO.
In soil, I run RO and add nothing....in the way of a bottled Ca supplement.....Just don't need it.

But where did he say "RAINWATER"?Wtf, now marijuana dont like rain water....

Rainwater is very, very far from distilled! Full of compounds it gets falling through the air!
GOOD STUFF though!

Depends on whare you are at. Our rain water tests less than 10 ppl. Also the only thing it can pick up is what's in the air it falls through. Definitely not ca. I have used distilled and ro. Whether you need to add ca in soil with distilled depends on how much ca is in your soil. Many super soil mixes will not need any ca added with the water.

Distilled water isn’t rain water. What is wrong with you ? Do you just come around RIU just to argue with people ?Wtf, now marijuana dont like rain water....
Id say go away but another self proclaimed preacher will take your place
I’m new to both RIU and just from the threads I’ve read your have EARNED a bad reputation around here. Ease tf up.

How is distilled water any different to the initial water vapour that forms rain? Ill answer that 'Its Not'
Secondly to say that water that absorbs Co2 is bad makes a mockery of the fact rain water does exactly this to form carbonic acid, apparently not in your clouds.
So back to this douches bold prophecy on distilled water and Co2.........

Whew buddy. You’re a lost cause. I don’t argue against science and I don’t argue with fools. Have a nice day bud.Ive earnt a reputation which is a damn site more than you newbie.

It is different by virtue of preparation and nothing else. Distilled water is distilled to be pure and packaged accordingly. Rain water may start pure but absorbs other chemicals along the way. Not interested in arguing the merits of using rain water in a garden, but they are totally different. It’s science. Use god damn google.

Umm, sure, right.......Rain water is not anything like distilled when it hits the ground...THAT is the real point....

Your reading comprehension in sad
It seems like you keep arguing points that no one makes and then lash out when people point it out. No one said CO2 makes water “bad” only that it will react and reduce the pH slightly from a neutral pH to a slightly more acidic one. Nothing about that says that water becomes “worse” to grow with. And distilled water is simply rain water that hasn’t passed through the oxygen and particle rich atmosphere collecting particles as it falls. Again, no one ever made the argument that rain water was bad. Seems like you just hunt for arguments and when none are to be had, you create them. Offer advice (a decent explanation or supporting link is usually a good idea for corroboration) or leave the unanswered questions to someone who actually cares and wants to help instead of arguing.

If you're going to use bottled water then "Spring" or filtered is what you want to use. But realistically most tap water is fine. It's already been prepped for human consumption.
The only thing cannabis related I use distilled water for is mixing a sodium thiosulfate and silver nitrate solution for making fem seeds.
I collect my rain water but it goes on outdoor plants. I don't use it on indoor cannabis.
