New Grower id like to find easy way to ph water for 15-30 plant.

[hello]

im trying to find a way to get my water ph to 6.5-6.8 easily.
right now it takes a lot of time to water one plant. I take my plastic gal. jugs and fill them with my filtered tap water. I have these sitting waiting for use. I also have my crystals ph up and down mixed in water jugs ready to use. so when I want to water I have a large drinking glass that I fill up and then stur it and try to adjust it to my ph needed. im using hana triangle shaped red color ph tester. this is usually pretty slow process. sometimes im waiting for hana tester to settle on a number,and other times im chasing the number up and down with ph crystals. its not fast or easy. I cant see this working for 15-30 plants. maybe I just need a larger mixing bowl,instead of my drinking glass im using for mixing enough for one plant at a time..
what all options are out there to make correct ph watering fast and easy? id like to water 15-30 plant easily,and fast.
thanks for your help.

Have you considered using a buffer? I know a chap who used a product for aquariums called Proper pH 6.5. You add a little of the powder to your solution and it will buffer it to pH 6.5. It is based on a potassium hydrogen phosphate buffer system, so also adds a small boost of P and K to your nutrients.

I use Plagrons Lemon kick-organic ph down..goes 0.5-1ml/l after u ad nutrients..pretty simple for me :)

Just use citric acid. A little goes a long way.
