whats happening folks
new here,beein lurking in the shadows soaking up some knowledge for a while
need a question or two answered from some of you clever people
firstly,when doing dwc bubblepots i know you need a nutrient reader,the other day whilst at my local hydro shop i was looking at the bluelab truncheon an saw ppm,cf,ec,ppm levels with blue lights but the looking at it advertised on there website it clearly says ph on the wand an has red lights?????but i never saw this one in there shop??
is there two different bluelab wands? why wouldnt ph be on the nutrient wand also?if theres two do you need both for dwc?or can you do it with just the nutrient wand???
thanks in advance kind people

I dont know...but i'd like to...i have one in the post no PH reading on then?

you would think the nutrient wand would have ph reading on it also?
an why has it 2 ppm levels?
can dwc not be done with just the bluelab?

Measure using E.C mate

so its fine not measuring ph an just going of the ec??

You will need a seperate tool for measuring P.H. im afraid, come manufacturers do combo measuring tools but youll have to scour the web my friend.

Blue lab sell a combo product but it's not cheap.

You'll have to buy both the wand and the ph pen £100 from Greens or they're about but one day I'm buying this
