Hobby pH Pen Size:Grow Gadgets pH Pen DWC and RDWC bucketsGet pH right before nutrients ever reach the roots The Grow Gadgets Hobby pH Pen is a simple, no fuss meter for checking the pH of your nutrient mix before it goes anywhere near your plants.

Dip, read, adjust, and you feed with confidence instead of hoping the mix is in range. Yellowing leaves
