Is PH checker really necessary?

So you can use just a lime fruit and put the juices in to change the PH? I don't understand what dolomite lime is. What are some practical practices to raise and lower PH?

Vinegar, baking soda.

I've done it before without a pH meter. I just used gallons of water from the grocery store that said the pH on the container.

growing herb without a ph meter is like fixing a car with just pliers sure it could work but if you had the right tools to begin with there would be no problems i found a really nice ph meter at homedepot for 15bucks just stick the rod in water or soil and the needle indicates where the ph is

Hello everybody,
Yes the ph is one of the most top causes of nutr lock out.Are you growing in soil or hydro?The grow I'am doing now has been a learning grow and yes I was not useing a ph tester.My plants would droop alot and the bottom branches bent down sometimes.Did alot of reading and started useing distilled water with a ph of 6.0 from wally world and got a ph tester from milwankee
When you add nutrs to the water mix it up good and let it set for a couple of hours,then do a PH test.In the veg. stage my nutrs would make the mix a high Ph and in the flower stage it is making it go down.But now that I test the PH I know that all the nutrs are there and they are not locked out.
My plants bottom braches stoped benting and the leaves are'nt drooping now.
Lights,Food,water start growing.Plants are like a car.You need GAS&SPARK&OIL to make it go.The better the gas and oil and the stronger the spark with timeing the faster you go.To get the best you can out of what you got put all your duck in a row.ZANDOR&LATEWOOD both said it best
GO CHEAP AND YOU GROW CHEAP. Thanks alot Zandor & Latewood I have learn alot from your threads and still learning
