No, I haven't, but I've heard it's really useful for measuring plant transpiration.

Root Explanation

Potometer → It is formed from "poto-" (from Greek "poton", meaning drink) and "-meter" (from Greek "metron", meaning measure). The word describes an instrument that measures the amount of water a plant absorbs, essentially measuring its 'drinking' of water.

Memory Tip

Think of 'drinking' ('poto-') and 'measuring' ('-meter') to remember that a potometer measures how much water a plant drinks.
