PH of Rain Water?

[Budsmoker187]

My pH meter may be malfunctioning but the rain water im gathering is reading 4.8... I am not sure if this is right because at first it was reading 7.5 which sounds right, but i recalibrated it to make sure and now its reading really low... Is it even necessary to PH the rain water, seems like soil+natural water=success?

rain water is bad mmmmkay....................

Rain water is something i wouldn't even drink myself all the stuff clouds gather in that water just nasty id drink my own piss before i drink rainwater..

Rain water contains nitrogen, as well as other trace elements beneficial to plants. Unless you live in an area known for its pollution, rain water is fine. Btw rain water is generally between 5.5 and 6.0, so unless its groundwater your meter may need a recalibration.

Bahah f#ck you must live in a shit hole area. There's nothing better for you plants than fresh rain water.

Absolutely wrong. Rainwater is the singlemost best source of water for any plant, period.

My girls have always liked rain water. Generally I use well water as it doesn't require storage.

Why would your rain water be acidic? And where in the hell is it picking up nitrogen from?

Rain water is just like distilled water, unless there is pollution in it, rainwater is plain old water and is usually right around 7 PH, not 5.5 or 6....

What if you refrigerate rain water, would that mess up the ph in any way?

Nitric acid in rainwater is an important source of fixed nitrogen for plant life, and is also produced by electrical activity in the atmosphere such as lightning. Rain ph varies upon location, but “clean” or unpolluted rain has a slightly acidic pH of over 5.7

Would you care to link up some source for me? My education needs to be adjusted perhaps. I'd really like to see that information in a science article or some informative site.

I just did some research. Sure as shit, rainwater PH varies sharply, depending on the source of the moisture. On the west coast, the PH can be in 3's! In electrical storms, as low as 2!

As far as rain having enough nutrients in it to support a plant, probably not, as rainwater has increasingly shone lower levels of nitric acid. This could be due to our ever changing climates, or the result of something we are doing on the ground. For a full read on rain and everything you wanted to know about it, check out http://en.wikipedia.org/wiki/Rain

And even after reading about rain, I'd still drink it WAY before I drank my own piss..... ;p

rain water is kind of like distilled, similarity is they both have 2 parts hydrogen and one part oxygen some molecular contaminants and some desolved solids in them.

when you distill water, you take out EVERYTHING for the most part is a desolved solid. When you Further RO the distilled water, you further take out all but the miniscule amount of non H2O molocules.


Rain water on is similar to distilled in that it evaporates from the ground, leaving most the desolved solids in the dirt, but once its re forming as droplets in the clouds, it re-aquires contaminants again, from wind born debris, and dirt dust ect picked up by mother nature, that mixes back with newly forming droplets of rain in the clouds. take rain water and distill it and be surprised at how much desovled solids are in the distiller afterwards. you my be surprised.

but unless you live in LA where Smog is just BAD, you wont find anything better than Rain water. and its true, Ph is not equal just because its rain water.


think about it, if rain water was bad, even by todays measurement of polutants, the earth would be brown, not green.

for what its worth,does MN run a PH test before she starts raining to water her world?

pH shouldn't be affected by heat/cold.

 

[Serapis]

Can you explain then how most PH meters also include a temp reading and they automatically calculate in the temperature?

Don't you like to post factual posts, rather than one's like this one that lack any fact or truth at all?

tbh i dont even check the ph and my past plants have grown fine.

 

[PurPle BuDs]

just bottle some tap water leave the lid open for 1 day then put the lid on shake and then water.

In most cases, with a good nutrient line up and good quality water, you shouldn't need to, but it is always best to be on top of it and know where your PH stands. You can avoid trouble early on.

that has absolutely nothing to do with the discussion at hand and it has nothing to do with PH levels....but thanks?

It's really interesting to think about all the variables that can effect rain ph, right down to a lightening strike!

And great link, Serapis
