Water pH Question

If I test 5 gallons of rain water in a clean plastic jug and then cap it will the level remain the same as I slowly use it?

Thanks very much in advance for any thoughts you can share.

Yes, it shouldnt change. But If you're adding nutrients, you need to test ph after adding them.

How long will it take you to cycle through that water? I would pour it into smaller containers with no air space left at the top and put in the fridge. That will stop bacteria from growing in water---well slow it down anyways.

It shouldn't effect ph in a sealed container I'd be more worried about the water turning funky before you get to use it.

It's best if you can chill it somehow, say you had a 3-season room or somewhere with a concrete floor. Nothing should really grow in it unless the temperature of the water ultimately makes it suitable for that.

The pH of rainwater is usually fairly good (5.6-6), unless you have acid rain. In soil pH of your water really isn't of great concern as it is for hydroponics.

Thanks all. Thats great information I can use.
