Why is measuring conductivity vital to the success of your crop?
Plants eat. They get their nutrition from minerals but they can only get all the minerals they need if certain conditions are right. A key thing that affects food uptake is whether your solution is acid or alkaline. This is measured in pH and a handy tool tool to measure the pH is our Bluelab pH Pen.

Once you have measured the pH using the Bluelab pH Pen and know your plants can get at the food, you then then to measure how much food is available.

Very nice little unit... Review by Dogboy
Overall Rating
After a couple of nightmare years with Hana meters I have made the switch to Blueab and am loving it so far. The guys at GrowersHouse knew their stuff and hooked me up in the shop with this meter. This pen is easy to calibrate and has held its calibration well so far. The service and knowledge at GrowersHouse is second to none, its a nice change from your regular grow shop attitude trip...
