The Bluelab pH Pen is the latest innovation for hand held pH meters and is the ultimate handy solution for measuring pH.
Hydroponic growing lets you give the best care possible to your plants. The quality of care is in your control.
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. We measure this in pH.
The clever little pH pen ensures you maintain the optimum pH reading that allows nutrients to be available to your plants.
