The cheap pen I bought off Amazon must have been a unicorn. I calibrate it once a week and cross check it with the strips every couple weeks. It’s been over a year and it still works like the day I bought it
Quick and right to the point I loved it brotha and not many people even say anything about storage solution so good work getting more info out there for everyone👍
Good video, as always. I appreciate you covering all the aspects of growing cannabis. Have a great day and take care. Enjoy the grow. 🙂
Hey bud! I would LOVE to take my cheap PH meter out back and run it over with a car. However, I can’t afford to do all that. And I assume nobody is going to Volunteer to send me a good one lol. Soo, i am kinda stuck. I would like to get a NukeHeads soil PH meter. Can you use your soil pH meter for checking pH in water or no? I kinda imagine not. I’m sure they don’t want to give you a meter that can do it all lol. You want to grow with synthetics, spend a hundo and buy a regular pH meter for water. You want to grow organics, then buy another hundred dollar soil pH meter lol. Now, I seen a vid where a guy talked about the blue lab truncheon. And he actually took soil and put it in a lil water and mixed it up and then tested that solution to get the pH of his soil. However, I’m curious how accurate that really is? Can’t be worse then the stupid meters you can buy at Menards for checking your soil pH. Those things even claim to test the NPK 😂🤣 very laughable. TOTAL WASTE OF MONEY
Bluelab guardian monitor (connect version if possible) is my go-to…I own four
I have bad luck with bluelab
Don’t like them
I have an hm ph pen that works phenomenal. Though beware I think I have a golden egg because they typically have bad reviews. I also have an hm ppm meter and don’t know how to test it against anything without buying another ppm meter but I hope and kinda think the tech there isn’t as sensitive and should be accurate.
check out the megameter from growboss it does ph & ppm in one but he also says you don’t need to store it in solution because you will be replacing the tip at least once a year anyway
Our great grandparents would laugh and shake their heads in disbelief at the ignorance of these so called growers today. They never wasted their money buying all the gimmicks to test their soil. They just knew the right amount compost and manure to mix in with their soil, and their crops were always great.
I purchased a ph and ppm pen what a waste of money for me. I grow in soil and ph is not a issue, test water at home with solution for ph once or twice a year. Never change brand of nutes and when I tested ppm with pen. The ppm was correct when I mix nutes to directions. No need to use it after that. Maybe in hydro you would want one and need one.
BlueLab instruments are absolute rubbish. DO NOT BUY THAT CRAP!
Is it possible to use the pen to measure the pH of water, or is it only intended for soil?
Thanks 🙏
Wow so funny and true, My wife is big into Hydroponics and plants some how she has been doing well, she bought a P.O.S "PH/moisture/light" analog meter probe off of Amazon for 14.99 and I swear the thing stopped working after 3 days that’s if it worked at all, No Calibration what so ever!! Same readings every time after 2 years. I just purchased her the Bluelab combo meter Plus Kit with a extra soil pen and cleaning kit for this coming Christmas. She will yell at me for the price but she works hard and deserves it seeing this is her big hobby that she enjoys.
You forgot to mention the fact that these cheap pH pens require specific powder packs 4.01, 6.86, & 9.18. Since these pens require frequent calibrations to keep their readings accurate buying these little powder packs is a bottomless pit. They lure you in with a cheap pen but what they really want is to get you hooked buying their powders that’s how they milk your money. I bought a cheap yellow one on Amazon but soon realized I couldn’t use it in my 4.0, 7.0 & 10 buffer solutions. I didn’t bother to see how long the pen would last, just sent it back.
Does that blue pen measure soil and water?
I prefer using the 4 color paper strips. Been using them for 25 years at work and i find them reliable and no calibration needed.
Vivosun PH and TDS are crap…. I purchased two and calibrated both at the same time. They never read accurately.. over 0.70 difference. Horrible.
Another great vid Matt!
The reason why is u use a cheap one and throw it away every new 3 month grow
will release them too eat the idiots
I did a simple “experiment” with a cheap Amazon ph pen. Bought it at the same time as my apera ph20 and calibrated them with the same solution, as well as store them in apera storage solution. Both have actually been on point. I double check with strips and the liquid that comes with ph up and down. I’m very surprised the yellow garbage has managed despite the calibration solutions being different ph levels. I don’t know that I would ever trust one solo, but when treated like a real ph meter, they do function.
Nailed it. My #1 piece of testing gear. I rock the Bluelab pens but I also double check with the GH drops.

Is the blue lab good for soil and water ph?
Thanks again. We’ll said
Hanna PH products are also great and long lasting.
PS…. I don’t PH
hanna for the win, at my grow
I use Hanna! It’s bulletproof, expensive but worth it!
Just looked at the price of the Bluelab stuff. Gulp! No. Not gonn’a do that. 🙁
Why not use say Coke to lower pH? Baking soda to raise it? Vinegar to lower. It’s not the space program people. No need to buy pH up and down $$$$. Simple stuff you already have at home.
I use my blue lab pH pen every day works great 👍
Blue lab all the way 💚 my irie genetics just dropped 🤤 very exciting, love from Ireland Matt 🍀💚💚💚🍀
Is the blue lab good for aquariums too ?
Good until it conks out. Smh
Fun fact – yes they try to sell us calibration solutions, storage solutions – and with ridiculous high cost. But yeah, crap is still crap. If they wouldn’t want to rip us off they’d sell or even donate us these needed liquids 😂
I had crap regular pH meter which worked fine – for a while. The cheap ppm meter is still kicking tho – but its science isn’t that complicated so it’s understandable.
Great informational video bro your awsome
Call me old fashioned, but I still use litmus paper and pH test drops to test my water. Scientists have used litmus paper for like 100 years now, so I figured it’s good enough for me.
matt,use that bacteria for skin care,it has much wider usage than just plants.
Try and you will see.
this is revolution
i understand that youre catch the things whats happened around us.
Take a care and big salut from Croatia.
Blue lab is a rip off
Amazon and big tech WILL be the downfall of society.
Ditto I have Amazon Specials and upgraded to lab grade PH and EC pens, and ordered extra 0H calibration and storage solutions.
I use the paper tabs. Once you figure out where things are at with your water and solutions. you should just be able to add a measured amount of pH up or pH down to your solutions and be good. It’s worked for me so far…
Bluelab is a great piece of equipment thanks photosyntech it’s boils down that if you can’t go through PROPER testing when problems occur you can be damaging your plants! Love the discord great source of information 👍
Been topdressing a few tbsps of oyster shell flour into my 20 gallon pot of no till on my first cycle….did this a couple of times. I put 3 full cups of it in when I built my soil in the first place. How often should I be topdressing with this stuff?
I’ve had my blue lab pen for about a month and I’ve just now re-calibrated for the first time since unboxing. I loved that my pen indicated to me when my PH calibration was out. The peace of mind with this piece of equipment alone is worth the purchase. I got mine on sale recently for about 86$ so that was sweet. Just like Photosyntech said, calibrate the pen, store it in storage solution, and recalibrate when the pen indicates its needed.
Guilty lol. I just ordered an actual good PH pen lol ✌👊
i promise i will get myself a proper PH pen…🤣
Hit the nail on the head there boss man! I really don’t care if it’s hydro, or organics. There’s going to come a time when your plants telling you something, when this happens the first thing I do is check the pH. That will tell you where the plant is at, and if the plant is able to pull everything it needs to survive. I.ean if your pH is 6.8 it’s going to struggle with the uptake of the immobile minerals.
Do you think that the soil PH tester(i think blue lab makes one) is more important to have than a water ph tester in living soil?
