Decisions on plant health need to be scientific and data-driven. Bluelab is some of the most important equipment we have on-site. Chlorosis, necrosis, toxicities, deficiencies and inadequate flower formation are all possible if pH and EC are not monitored.

Bluelab pH Pen is a great pen. Fast to stabilise. Reliable and stays within calibration of a point or two tops for months when maintained with storage solution. Easy to calibrate also, just buy the two calibration standard solutions, it is stable for years and just keep well sealed for storage.

I use the Pulse from Bluelab does a great job and allows me to set various substrate blends which comes in handy when running so many different ones. It takes some calibration to your substrate but from there is pretty accurate. It's great for gaining consistency and improving on things like water and nutrient savings.
