skip that. get a HM digi EC meter for like $30 bucks off amazon. had mine for 6 yrs now, no issues. spend more on a good pH unit, not so much on EC/ppmSweet I looked It up what is the diference between ppm 500 and 700 scale and which do you use?
Im planning to use nothing but AN for my grow im hoping i wont even need a ph meterspend more on a good pH unit, not so much on EC/ppm
Little late for that lol I bought the complete Advanced Nutrients line I want to see how it produces in this stealthbox I bought.You'll need to check PH no matter what, AN is all hype.. Save your money and go with a different Nutrient Company that doesn't spend so much on marketing which in turn doubles the price of their product... You can buy a cheap tds meter off amazon but you'll want to spend around 75- 100 on a decent PH pen...
oh, it's perfect all right. just follow the advice on the website. don't leave out any bottle they recommend though. big trouble.The stuff is supposed to be perfect ph i think
cool i got them all loldon't leave out any bottle they recommend though. big trouble.
