Is it possible to have a hydrponic system without a ppm meter???

Cause those things are expensive. If not, know were i can get a DIRT cheap one?

Good Growing...

check online, htg supply, just goggle that shit and look

You can have a aero/hydro system but you cant grow right without a ppm and ph meter.Go on ebay they are about $30 each new

So i take it that mean it is a must....

Is there a particular brand, or the cheap o one are ok too... Wow i didnt know that they were soo cheap..

im also getting one some time very soon and found this site they are less than 30 bucks but i dont know how good they are anyone know if they are the right ones?TDS Meters

they got ones that go up to 9999 ppm so that would work right? and its less than 25 bucks

Yea, cause i dont wanna kill my plants cause i was too cheap to spend $30, considering all the money i have already spent... I just always seen them for $2-3 hundred dollar but $30 to $50 isnt bad at all...

unless i hear from someone that the ones on that site wont work ima buy one now im just gonna look around for a cheap digital ph meter cause this color matching game sucks lol

You can use any kind.The more you pay the longer they last. I paid like $5 for my truncheon wand (tds,cf and ec meter) and I paid about $24 for my ph pen.As long as the ph pen is calibratable and the ppm meter will go to 9999 it will work

what is the highest ppm you get up to during your grows?

Go to ebay like Flithy said, they got a bigger selection and better prices..

Highest I have taken any grow to safely was about 1650 with Fox Farm nutes and additives in an aero grow

ebay has tds for 10-15 and ph for 20-30 both hanna base model, so 30-45 plus shipping and you have both, those are buy it now prices too

Hygronomics.com, pm green1, tell him p sent you

tds/temp pens, 35$ + 4.95$ s+h....

The cheap PPM meter on ebay is good, I believe it's made by Hanna. The PH pen by hanna is also nice, but needs constant calibration every 2-3 weeks. Be careful if you do choose to get those meters cause if I'm not mistaken one company that sells them is in hong kong or something, and the other is more local. I paid around $50-$60 for both meters, maybe less.

Ive had my ppms at 1600 with no nutrient burn. but thats when they are hardcore agressive flowering. i suggest getting a good meter that will last a while, since u tend to use them once or more every single day.

I paid 200 for a Bluelabs combo meter 2 years ago, it recently shorted, and I purchased the Hanna wands until I get my meter back from warranty repair.

The wands seem to be working fine.

I've used the el cheapo ones for 6 months now, no problems ( except of course when I misplace them )

cant be misplacin em, that would drive me nuts! i leave mine on top of my res.
