Lotus Round-Tipped Dropper: PPM Values Guide

In Scott Rao's article about the Lotus water drops, he explains how each drop affects mineral content in ppm. However, his article references the older straight-tipped dropper style.

For the current round-tipped dropper:

For 775ml of water:

  • 1 drop GH adds 10 ppm
  • 1 drop KH adds 5 ppm

For 1 gallon of water:

  • 1 drop GH adds 2 ppm
  • 1 drop KH adds 1 ppm
