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!

        Clear mineral sunscreen!
        Style: Kids SPF 50 Mineral Sunscreen Lotion, Size: 3 Ounce (1 Pack) Mineral Sunscreen
        We have a beach trip coming up and needed to get some good sunscreen to use. We have used mineral sunscreen for years ( there is so much nastyness in regular sunscreen) but I have never tried this brand. Mineral sunscreen typically has zinc oxide in it and this one is no different. One thing that I have never liked about mineral sunscreen is that it always leaves you with a white film on your skin. This one is advertised as "drying clear" so I was really curious to try it out! I was pleasantly surprised to find out that it truly does! I'm so excited to not have the nasty while film all over our skin!

        I love this stuff!
        Style: Kids SPF 50 Mineral Sunscreen Lotion, Size: 3 Ounce (1 Pack) Mineral Sunscreen
        I really love this sunscreen. There are three claims on the front of the tube: dries clear, for sensitive skin, and lightweight. All three of these are true. It is more of a liquid and less of a cream which makes it easy to apply. It feels lightweight on my skin and sits there as a thin layer rather than a thick one. Some sunscreens feel too heavy or greasy to wear on my face, and this does not. It also dries clear as advertised. In addition, it smells wonderful. The scent is not like sunscreen at all which makes my daughter very happy. I like that this is a 3-ounce container and that I can take it in my airplane carry-on.

        Hard to rub in. Leaves strong white residue
        Style: Kids Mineral Sunscreen 5 oz Lotion - 50 SPF
        So hard to rub in. If you have squirming running toddlers this is impossible to apply.
