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. With continuous readings for pH, conductivity (EC/ppm/CF/TDS) and temperature, this device provides all the information you need to ensure that your plants are getting the nutrients they need. Its plant-safe green LEDs and silent alarm system make it easy to use and monitor your grow room without disturbing your plants, and its water-resistant design ensures that it can handle the wet environment of a hydroponic or aquaponic system.

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!

        Peacock Blue
        Size: 6.5x10ft, Color: Lake Blue
        Not out yet because of weather, but it looks good, unusual point that some of the spokes according to the directions need to be put on yourself, but at least this way they not bent in box. Note when I bought it - it used the color Lake Blue but the picture was a Peacock Blue - I took the chance and it is a Peacock Blue- I would not call it Lake at all or sky or any of those colors. It worked out for me as it matches perfectly with my Peacock Blue cushions and other umbrellas, It defintiely seems like it is sturdy and the size looks as it should, it has a nice weight as i did open it in house to take a look, the material has a slight sheen which makes it appear a little different than my others, but not something most people would notice.

        Attractive and seems like it will hold up
        Size: 6.5x10ft, Color: Blue-Green Stripe
        Seems sturdy enough. Tilt button is difficult to retract to straight, but maybe just my finger strength, or it will loosen up with time. The color of one of the stripes is off from the photo. I was hoping it was turquoise as shown in picture, but is actually a much deeper blue. Doesn't coordinate with my other patio colors like I hoped it would, but it will do.

        Love the rectangular shape, it allows more coverage in areas that I need it. The tilt feature works well and is handy. Easy to put together and would recommend
