  • Dependable and accurate
Style: Bluelab Soil pH Pen
Blue lab makes some of the best equipment out there. I’ve used their meters for over 15 years now and they have never let me down. Give you accurate info so that you can keep plants at optimal nutrient uptake for the best and fasted growth.

  • This WORKS, if you read the directions!
Style: Bluelab Soil pH Pen
I read the reviews on Amazon BEFORE I bought this and quickly realized that the primary 2 issues that people had was that the probe holder wasn't included when they shipped it, and that you need to calibrate this after each use. Well the probe holder was attached, and I didn't realize it at first until I carefully looked at it and then realized that you have to unscrew and gently pull it out at first. There should be some solution in the probe holder when you take it out, so be careful. If there isn't a cap, nor solution when you pull this cap off, then you've got a defective product. I bought both the calibration solutions, AND the storage solution and was prepared when I first started out. I'll have you know that this product SAVED my butt in that the cheap "two-prong" old style PH meters said I was at 9 PH and I almost did some damage to my plants using the PH Down nutes. I used it tonight and it said I was at a 5.5 which is borderline TOO LOW! If you read the directions and take your time, this thing is INVALUABLE!!! I HIGHLY SUGGEST THIS TO ANY NEWBIE OUT THERE, JUST DO YOUR RESEARCH AND FOLLOW THE INSTRUCTIONS PEOPLE! LOL ... show more

  • Precise and a joy to own.
Style: Bluelab Soil pH Pen
I got the solution to assess the calibration of the bluelab pH pen and been detecting consistent data for water and other solutions. Perfect for knowing how to keep my drinkables at a higher pH so to balance my acidic diet of foods. In doing so, I detoxify my body every day and help the digestion of foods work as it should. In this age of modern polluting factors (a mountain of factors, really) our basic water and other fluids are poisoned by chlorine, chloride , flouride, and other unwanted pollutants. These products change the water pH. Our natural streams (with higher pH because of magnesium and potassium) are no longer the standard we evolved to intake. This other water, delivered via pipes or with well shock treatments with Chlorine isn't part of our evolutionary diet. So the Bluelab Pen permits me to make sure what I drink is going to be something I've evolved to drink that helps me balance the toxic effects of too much of one thing (acidic foods that need to be digested and distributed by alkaline fluids). ... show more

  • Reputation for a reason -- UPDATED
Style: Bluelab Conductivity Pen
I started with ordering the grower's toolbox at the very end of January -- it was delivered February 1st and the EC pen was dead before June 1st. I figured that it wasn't too serious, since sometimes these things happen and it should have a warranty. In the meantime, I decided I'd order a new EC pen since I have to make sure to feed my plants properly -- they're very picky. The new pen arrived within days and after thoroughly cleaning and rinsing, as instructed to before calibration, I attempted to calibrate the new EC pen. No dice. Tried cleaning and rinsing again -- nothing. I contacted Amazon and got a replacement sent (props to Dash for getting me taken care of quickly and painlessly), and tried to clean and calibrate the NEW EC pen...to absolutely no avail. Still getting "Er" code on the display. So it seems that no matter what I do, Bluelab products are simply not worth the effort to try and use and DEFINITELY not worth the cost. It's a shame, really, because I feel like I remember their products actually working when I first started using them 3 years ago or so. I will be looking for a new manufacturer for my plant feed analysis products and highly recommend that anyone reading this review does the same! UPDATE: After having reached out to Bluelab and left a message, I received a call back from a representative that asked for some details related to the products. She guessed that the EC control I was using was expired and sent me new EC solution, as well as pH probe storage solution and pH 4.0 and pH 7.0 controls. After cleaning the probes again and using the new solutions sent to me, both pens (pH and EC) were able to be calibrated. I was told that if, for whatever reason, the new solutions didn't work to contact Bluelab again so that they could rectify the situation. All in all, I'd buy this product again, but probably directly from Bluelab since they pointed out that solutions in/with products sold by other parties may be past their prime. ... show more

  • Works great for me.
Style: Bluelab Soil pH Pen
I bought this after my other pen quit working, and I wanted a good, easy way to check the soil, or coco's PH. I saw a lot of reviews about this not working, and I had problems at first, but all you have to do is rinse the probe in clean tap water before using, to get the storage solution off the tip. I like that the storage solution (Buy some when you get the meter, you will need it immediately) is a constant PH of 4. That alone helps me keep an eye on the probe to see if the numbers are drifting on it, and whether it needs premature calibration. My plants are growing beautifully now. Thank you. ... show more
