I have one on the way...anyone else got one?
any comments?

i have had the ec reader for many years never let me down

What exactly do they measure? nutes i know but whats EC/CF?

electrical conductivity/conductivity factor, they're basically two ways of quantifying how easily an electrical current can pass through a solution. The PPM is calculated from the ec/cf.

This might sound stupid but why would you need to determine the cheers

brilliant bit of kit :-)

if you're hard water, just descale the end very infrequently, 6 mths or so

Hi, i bought a blulab a few months ago, im currently on my 2nd grow with it and i love it already. I've skimped on stuff before when trying to save money and usually i dont save money cos i end up having to replace stuff i bought with better stuff. I cant check the link you gave cos its been removed but how would you know what you are buying is reliable? You dont unless you know people who have used it, reading these forums i know everyone whos used a blulab is happy with it so thats reason enough for me to try it. I Paid £50 with delivery for mine brand new, bargain. I know that it will last me years, plus the 5 year guarentee it comes with says alot.

cant go wrong with blulab tbh,

I have a truncheon from when they were called NZ hydro(several years ago) & its still bang on calibration wise...

My bluelab trunchon has just come through the door

personally i think they are

Why?

ya can not calibrate em and they do go out in time

hey Hipgnosis i'm sry for posting the ebay link i dinent know that its forbiden here..... all i wanted is to show the guys some cheap alternatives and to see what they have to say bout it..... no ofence man!!!
my point is that, can i get the same results without a bluelab meter couse its real expencive for me, i know its good and worth the cash but i just cant afford spending 50 quid's on that.....
PEACE

congrats man&good luck!!!!
may your grow will be easy and allways green!!!!!!!!
Peace
