Does any of this make sense to you all that may be able to answer if these are good readings? Just a app without attachment meter.

100% of people are going to tell you to get Photone. It’s a light app. It works great. I’m new to using it and it has made things so simple! ---

> [@Start using DLI](https://ilgmforum.com/t/start-using-dli/64987): > > Daily Light Interval (DLI) is a quick and efficient way to calculate how much light our plants are receiving within a 24hr period, allowing for easy light adjustments. DLI will help you and the community to better understand your lighting in a more universal term, leading to clearer communication of what the true light value is. Almost all smartphones have the ability to use an app (we will get to this don’t jump the gun) in order to calculate DLI, and if that is not an option a cheap LUX meter… Also check out this thread. Has amazing information and a chart to follow. Really explains lighting and dli ---

@WaPNWGrower For sure man, a lot of people are getting dragged on social media for heading over to help but i think its false patriots and keybord warriors running their flappers, whats going on there is a shame and good honest folks are suffering. Yes i do have it set to day. ---

Okay so with it set to daylight your going to want to adjust your light to make the dli reading match the numbers on the graph in relation to the age of your plant! ---

You can either mirror with one exactly or use either one as a baseline to adjust. But most importantly watch and listen. Your plants will tell you what they like, want, and need ---
