PH tester equipment??

[MrPuffAlot]

Looked into PH testers..

Every MJ grower should have one right.

But I was suprised to see how much some of them COST.

***..

is the "cheap" $40 pen tester good enough??

Or is the pricey $100++ PH testers needed???


THanks..

I paid $10 for mine on ebay... if u use electrode storage solution ($4 a bottle) it'll easily last a year...

Kade, but you use Hydroponics.
easy to test for PH when you have real water samples.

I want to know what the best way to test for PH for soil.
What kind of tester.

Or is the simple PH paper test sufficient??
