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).

Coco is the same as hydroponics so shoot for a ph that swings from 5.3 to 6.3 that way all nutrients are uptaken. Also don't forget to add a calcium supplement like garden lime or cal mag from botanicare or whatever brand you like. **Q: Can you read nutrient solution PH with this as well?** A: Yes, it measures both soil and liquids. Gives the temp and pH of both. **Q: Can this device measure PH of soil outdoors?** A: Of course **Q: Do you sell the glass with sensor replacement for this soil ph pen?** A: I’m pretty sure that it’s a one time pen unless you get the other unit with the replaceable heads ## Customer Reviews ### ⭐⭐⭐⭐⭐ Precise and a joy to own. *by J***S on July 16, 2021* I got the solution to assess the calibration of the bluelab pH pen and been detecting consistent data for water and other solutions.

I loved the way it tested the ph of my plants in an instant. I went around my little nursery and was able to test them all. I had crazy results, no wonder my plants were not doing well. So they found themselves back on their way. They started to look sad again, within about a week and half. Something wasn't adding up with my mix, there was no way the ph should be that high and I should have to be adding that much ph down. So I recalibrated, and same thing. Who knows? next day half my plants appear dead. I tried to recalibrate again, this time it would not pick up right, the 7.0 solution was picking up 10 and the 4 was picking up 7. I returned and amazon got me another the same day. So I calibrated that one, the solution rang in at 3.1! I was p***ed So I think just got a dudd. I got this last probe march 1st. It started acting up 3 days ago, the screen started to morph to unreadable, temps reading over 180. Are you serious!? I use this multiple times a day. this is a huge expense as right now I am entirely self funded. I work on research on propagation of endangered native plants. There are downright impossible sources to come by at any rate, but to have them fail like this, from errors of a pricey product that I purchased to make it easier to restore them to the environment, this gets them a rating of 1. My heart literally breaks with each loss of plant life that I lose. I cannot just go and buy this stuff at Walmart. I am at a loss and have no idea where to go from here. ***update, I went ahead and got a new pen less than 1 week ago. this makes three in less than 2 months. I have had in the past 2 days, 2 seedlings that have never been cultivated grow. by changing the ph just a small amount. Ph meter worked great all day. Tonight, its not working, screwed up reading, always reads 7.3, will not calibrate. never ever again bluelab. The Dollar tree makes products that last longer. ## Frequently Bought Together - Bluelab PENSOILPH Soil pH Pen, Digital Meter and Water Test Kit, Also Used for Coco and Rockwool with Easy Calibration for Hydroponic System and Indoor Plant Grow, Clear - Bluelab STSOL120 KCL Storage Solution 120ml pH Probe and Pen, Maintain Meters Used for Water, Soil, and Hydroponic System or Indoor Plant Grow White - Apera Instruments AI1113 pH Calibration Buffer Solution Kit (7.00, 4.00), 8 oz.
