Blue lab every time once use one you won't touch anything else!

which blue lab one?

i only got a few plants with ebb setup. do i need to have an expensive one still?

yes that ones fine dont forget to get the PH pen also

The build quality is worth it for both bluelab truncheon and ph pen. I cheaped out on my first grow and bought the cheapest ec and ph meters i could fine. Readings were completely wrong and i almost lost my babies do to overfeeding and nute lock from off ph readings. Get yourself a bluelab i guarantee you won't regret it. If your low on funds though ph strips are very accurate but you may need a few to make sure ph is good to g
o.

I have posted so many times over the past 2 years about this shit! Most will try to tell you otherwise, because they have NOT used this meter! Yes there are other good quality brands out there, but this one plain and simple; just works! I can personally back this product! I have used several different meters over the years, and this one is the cat's ass! It works! Continues to work day in and day out!

I have stated in other threads of how I calibrate it once per grow, just because!(usually does NOT require adjustment, and if it does, it is by a point(2 at max!)

I am a firm believer in spending the money when needed. You can purchase lower quality instruments and will be required to replace them on a much more frequent basis! I have never looked back after purchasing my Nutradip Tri-meter!

There is also a bonus feature of this unit! You can replace probes! So, no need to purchase an entirely new unit ever!

cheers guys. i had a bit of a problem, too much water, rotted the stems of 2 plants, so a friend cloned them for me and put them into coco coil soil in pots. so looks like i might ditch the ebb and flow system.

is it still as important to check TDS and is it the same meter?
whats the difference between these 2? any good?

Thanks greensea, havent seen these ones. i know looks are not to go for on meters, but they do look good!

many of the cheap pen type PH meters are next to useless they give totally random readings
i would avoid them like the plague , the more expensive PH meters with replaceable probes are the ones to go for
or just use a liquid 6-8 ph test kit they are accurate to .2 which is good enough

the cheap pen type EC meters are not so bad at all, although they tend to measure a little on the low side
full strength 2.0 EC on a freshly calibrated pen measures 2.6 EC on a blue lab truncheon

peace

whats the difference between the 31 and 32 (high and low)?
and the difference between 33 and 34?

i was thinking something more like this

http://www.amazon.co.uk/Bluelab-BLU2320E-pH-meter/dp/B003WOR5PO

this thing cost £130 i have seen similar style with replaceable probes for £90 or so
your one cost £25 from my experience of using a few different similar types in that price rage they are not reliable and give
fluctuating readings

Ye i hear good things from blue lab, but its too expensive for me, and i need a TDS meter as well on top of that. But then again, whats the point if non of these cheaper ones are accurate.

I agree bro,I use the bluelab ppm pen and love it,the blue trunchuoen is the shit also.My ppm pen was 100 bucks or so

My water PH from the tap after mixed with nutes, and 1 drop of ph down measure about 5.8 in 20 litres of water ebb and flow (yellow in colour with ph tester dye) Do i really need a PH tester worth £100 for 3 plants? im also thinking of moving over to coco coir, as the rock wool idea isnt for me, because i cant keep the water temp down enough, and i rotted 2 stems already..

The Bluelab Guardian is the bomb. I fitted the PH probe and the Temp/PPM probe to my Waterfarm and I can tell you its made me a better grower. having the PPM and PH right there displayed on the meter ALL the time is priceless info. its helped me "dial in" my plants. being able to watch your plant react to different ph levels and different ppm levels is so much easier when you can just glance at the meter and have all the info right there. i wont grow without it again. a lot less work, and a lot better results...for me anyways ...
