🌱 “I was doubtful about spending the money for a ppm pen, but I took the plunge and could not be happier.
✨ This pen is very easy to use. You can change the pen to read PPM in the 500 range, 700 range, and EC.
🌿 My vegetables’ leaves were looking very light green, almost yellowish. Once I started using the pen, I was able to adjust my nutrient solution into the proper range… and within a couple of days all the leaves started to look healthy with a dark green color.
🔋 This pen uses one AAA battery. The display also illuminates when you turn it on, off, and use the hold feature. I didn’t realize it illuminated until I used it early in the morning.
🌟 Get this pen and happy growing.” – Z. Ohana
