it is used to test the dissolved solid content of your water. Aka how much crap is in your water that the plant wont use.

that is not 100% true, just cuz you have crap in your water, does not mean it is of no use to a plant, kinda like buying an RO system then adding cal mag, a ppm meter or tds (total dissolved solids) meter will be useful in telling the strength of your nutrient solution, also for testing your tap water.

my friend had a ppm meter laying around and donated it to me. i just dont know what to do with it? lol
do i measure the ppm of the water i am going to put in my coco
or like the nutes? or what?


this is the one

They are handy tools used to measure parts per million of dissolved salts as has been mentioned in previous posts. Use it to figure out the dissolved solids in your tapwater (if you use tapwater) for a baseline and then use it when you've added your nutes to see how strong your solution is. The problem with the one you've got is it only goes up to 999 ppm. A lot of nutrient schedules will have you going past 1000 ppms with the typical max being 1500 or 1600 ppms in a full nutrient solution.

Agreed, When I am at full strength in flowering I run around 1700 to 1800 ppm. Depending on the strain.

i spent 999$/1000$ budget. is there any way i can use this with my set up? the only nutes im using is rhizotonic, canna a+b. and earth juice


im growing iced grapefruit and im about to get abunch of bag seed

uhhhhhh, wrong answer.... it does indeed measure dissolved solids.... but it isn't crap and the plant will use it...

Like Serapis said it'll be useful in the beginning when the strength of your nutrient solution should be lower than 999 but after that it's not much use. The TDS meter I have is quite cheap @ $23 and it works just fine.

uhh not wrong answer. it is used to test the crap in your water you the plant wont use (reason people buy r/o filters) and the nutrient solution. Not everyone test their nutrient solution with it, with him not knowing what it does, thats about all he will use it for! I have been growing beautiful plants for years and never once tested my nutrient solution ppm! most of that is done for you if you read the bottle. not all plants are going to need around 1700-1800 ppm. people may say the get better results from all that testing but I get great results with out! does anyone here that actually tests their solution ever have the bud tested to see if the results were any better? doubtful! So short answer for some one that is new to growing Test for crap in your water the plant wont use!

most tap water is fine for plants, people buy ro systems if they have very hard water or well water. But the tap water contains minerals that the plant does indeed use. In the nicest way possible you are mistaken.

before you make stupid replies serapis maybe you should know what they are for! read wiseguys first post "not 100% true" thats just because i didn't add the part about the nut. solution. Which i'm pretty sure is fine because he should figure out how to test his water before testing the nut. solution!

and not all nutes are the same. you are going to need more of some and less of others so your ppm for your solution is going to be specific for you solution

is there not calcium and magnesium in the tap water? those are not crap nutes, done with this thread, i tried to be nice.

different cities have different wells! check your cities water report before you say i am wrong! you can live on one side of the city and get totally different reading than the other side! There is more crap in tap water your plant wont use than the is that it will use! so no people don't only buy r/o filters for hard water! I use it for all the CRAP in my tap water and mine is cleaner than the link i listed! So no im not wrong! it tests for crap in your water the plant wont use! I would never use strait tap water! so if you claim to be organic and use tap water YOU'RE NOT! I AM!

This could be used with hydro as long as you have a somewhat accurate measuring devise. Find the ppm of the water and use this as a zeroing figure. Add a certain mL of nutes and then reread. You should be able to extrapolate how many mL you need to get to a particular ppm even if the reader only goes up to 999. Fucked once it fluctuates though.
