### 3/5 — Can’t change voltage from 120 to 240v

*2020-03-18, version 0.4.1*

This app would be better if you can switch to 240v

**Developer response:** Hi Jclarkhvac,
Thanks for taking the time to review the app. I have incorporated 240v, and 210v volt options because of your feedback. Please update your app to see these changes. Best, Grow Room Calculator
