I developed this app for personal use because there is nothing else out there with a solid green screen for use in indoor grow rooms while the plant light is off. This app is not for growing plants! It is for viewing them in the dark. Please read the description. This app includes NO promotional white text and/or buttons like some others I've tried.
The app is totally safe for downloading. Timothy Johns is the developer of Hydroponics Green Screen Light that can be found in the Lifestyle category. Over 50K users downloaded the tool and the most recent update was released on Jan 12, 2016.
