Bluelab Guardian Monitor Measures PH + Conductivity (EC/PPM/CF/TDS)

The Bluelab Guardian Monitor is the perfect tool for any hydroponic or aquaponic grower looking to optimize their nutrient solution for maximum plant growth.

Ensuring your pH is correct allows for your crop to uptake nutrients efficiently. Without monitoring your pH and EC levels, you're essentially growing blind. pH and EC measurement are basic tools on the belt of a hydroponic farmer.

pH is a measurement of the acidity or alkalinity of an aqueous solution and should always be monitored in hydroponic/aquaponic cultivations to ensure that your plants are able to uptake nutrients effectively. EC is a measurement of the conductivity of water, or the amount of dissolved mineral nutrients in a solution.

Bluelab tools are convenient and accurate for home or commercial growers!

Bluelab is a New Zealand based manufacturer that is globally recognised. They have been engineering water measuring technology for over 30 years!

        Perfectly Practical and Stylish!
        Color: A-silver
        This product does exactly what the description promises—and more! The silver metal caddy is not only sturdy and well-made, but it also keeps all of my items neatly organized and easily accessible. I love how sleek and modern it looks on my countertop. The design is thoughtful, with no water leaking from the bottom, and the slide-out tray collects any runoff, making it super easy to clean. It holds a surprising amount of items, including my dish soap dispenser, without feeling cluttered. For the price, this caddy offers fantastic value. I’m beyond happy with this purchase—it’s a game-changer for keeping my kitchen tidy!

        Less mess, more style!
        Color: Gold, Color: Gold
        So happy with this purchase! I was a tiny bit wary buying an item without any reviews yet, however I saw that the other caddies from this brand all had many positive reviews and seemed to be good quality. The diatomaceous earth base of this caddy elevated this option to me, so I went for it. I've had it out for a few days and am extremely happy that I went with this option! It absorbs water super quickly, so there are no more rings and residue left on the top of my sink, and it makes my countertop look that much more cute and put-together. Heads up it is a little deep compared to some other trays/caddies; I knew this ahead of time so planned to put it directly to the side of my sink so that it did not overlap. I think the size is worth it, since it accommodates about 2 soap products and has plenty of adjustable room for bottle brushes, sponges, drain stoppers, and whatever other items you need. Overall, I highly recommend!

        Sturdy and does the job well.
        Color: Black
        Very stable. Have a narrow ledge on my sink and it balances great without falling. Holds all my sponges and brushes and dish soap. Hasn’t rusted and I’ve had it for a while now. Looks nice on my sink. Keeps my counters dry and my sponges mold free.

        Buy it you'll love it. You'll realize that you really needed it
        Color: Black
        Size is perfect for rag, scrubber sponges soap. It's very sturdy love that the block on bottom dryies up all the liquid it's absolutely amazing. It's very convenient, love the way you can organize everything. I'm the kind of person I have to have everything organized that's the way I grew up. I have not seen any signs of rust no where. Highly recommend. It is very very nice.

        Funcional but smaller than I thought
        Color: B-silver
        I liked it and it replaces something around the kitchen sink that was constantly dripping liquid soap dish into the sink making a mess! This new organizes items much better. It's smaller than I envisioned and wish it came with it's own soap bottles dispensers but I found two small ones placing them side by side and it works. Did not use the metal divider. I cannot tell yet the drying speed of the sliding out stone. It's functional at keeping everything hands reach and organized around the kitchen sink.
