Great video, thank you!

[@malikstiffler]

“ this isn’t waterproof don’t let water go above this” as you put water above that exact line 5+ times 😂😂😂😂

whene i calibrate my pen,i can use only the solution calibration 7,or for right calibration i need also the "4"?

[@RichardPeterson-de2fh]

Why use two types buffer when the exact directions say to use the 7.0 that’s supplied with the meter. Especially when just growing marijuana

[@basilg695]

Thank you 🥺

[@scotth8002]

Why do 2 point calibration if it's a one point calibration unit?and it comes with 7 ph did u read the operation paper?

[@juanmora4113]

That's what I was saying, like wtf I only got a ph 7.0 buffer solution, and this people has something else

[@dannycastaneda1974]

Helps with accuracy

[@miikesnow50]

Good stuff

[@thatswhatshegrows]

It only came with 7.0 can I do it without 4.0

[@RichardPeterson-de2fh]

Yes. If growing plants you do not need to be exact! Weed has a good range of ph needs and you DONT need the 4.0!

[@bbab9051]
