    A must for any serious grower - well made and so easy to use! :)

  2. Idiot Proof review by Budmaster on 09/02/2016

    I've always really struggled with measuring meters/sticks etc and nearly killed my plants on many occasions. The Bluelab truncheon makes things unbelievably easy, just stick it in the solution and a big blue light highlights the strength of your plant feed so you can avoid soooo many potential growing problems.

  3. Makes testing nutrient strength simple! review by Flower Girl on 09/02/2016

    So easy to use, I didn't even have to open the manual as there are no buttons or switches... It's a little more expensive than a standard ec metre (i've been through a few lol), but well worth the extra pounds as I love Bluelab products.
