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!

        Waterproof
        Size: 5 Ounce (Pack of 1)
        This product is great for kids in the pool or ocean. It is very waterproof and you can even see the water beading on top of the sunscreen. It doesn't go on super clear, which can be an advantage for determining coverage. One other unique feature is the bottle itself changes color to indicate it is currently exposed to UV light although that is basically anytime you walk outside in daytime.

        Good sun protection but leaves white streaks after sweating
        Size: 5 Ounce (Pack of 1)
        I really wanted to like this sunscreen after seeing it make a lot of lists for best sunscreen for runners. But for whatever reason, about 15-20 minutes into my runs and I've started really sweating, I see white streaks in my elbow crease. I've started developing weird tan lines in my elbow crease if I don't consciously try to re-rub and re-spread the sunscreen in my elbows periodically during my runs. If I only use the sunscreen for lower impact activities, I don't get the white streaks. It's as if from the sweat it pools the minerals from the sunscreen into my elbow crease. But yet I don't have that problem with the sweat mix with my sunscreen on other parts of my body. I've also switched to Australian Gold Botanical Mineral sunscreen which ironically isn't meant for sports, but I don't have the elbow crease white streaks issue with that sunscreen. I will say, this Blue Lizard sunscreen does rub and spread easily and doesn't leave a white cast after rubbing it into my skin. Although it does feel mildly greasy after I'm done applying it everywhere. I've switch to Australian Gold Botanical Mineral sunscreen which doesn't feel greasy but it does leave a slight white cast on my tan skin, but I'll rather have that than deal with frequently needing to re-rub/re-spread the sunscreen in my elbow creases when white streaks form.

        Go to sunscreen!
        Size: 5 Ounce (Pack of 1)
        Mineral based sunscreen was recommended to me after second degree burns. I love how the bottle changes color when UV is bad.

        Superb Hidden Treasure of a Sunblock
        Color: White, Size: 6 Ounce (Pack of 1), Style: Baby
        If you're spending 100's of dollars on top of the line SPF serums etc. that are just an ounce in size forget about that. This is sublime. The stuff is like magic. It makes my mid aged skin glow and stay moisturized AND blocks the pigment causing UV rays. I've had plenty of photofacials to treat dark spots and without mineral protection I find they just come back over and over. This works great for the times I can't have a hat on or areas of my face (or hands!) that are difficult to keep covered. No smell and for me the best part is NO IRRITATION WHATSOEVER to my eyes when even things that say they won't irritate eyes do. This stuff is GREAT!
