Hey all, i have my ph meter coming this week do i also need to get this meter aswell: EC/PPM/CF Meter

thanks
 
Yes you need the ec ppm meter. I didnt know i had a crap load of minerals tds in my water and over fed my plants. you may be starting with 4-500 ppm before adding nutes and if you dont account for them you will over feed your plants or even lock out your nutes.
 
Noone even asked if you are growing in soil or hydro. If you're growing hydro, then yes, you should really get a TDS/PPM/EC meter. If growing in soil, i'm of the thought that you don't need one.
 
growing in hydro - many thanks, dont think ill give them any nutes until the meters arrive, thanks
 
so looks like i need to get a tds meter too, is this a must?
It is essentially the same thing.
EC=Electrical Conductivity
PPM= Part per million, calculated either by ECx500, ECx640, ECx700 depending on the brand of meter you buy
TDS=total dissolved solids, http://en.wikipedia.org/wiki/Total_dissolved_solids

You really only need to measure one of these, i prefer EC because it is a universal rate and doesnt fluctuate based on brand of meter.

thanks so i take it you can calculate the tds from the other readings.

the stick measures ppm, ec & cf

will this and my ph meter be fine? is there anythink else i need? thanks
