I am using a app called light meter for Android. So far the numbers Farside has thrown out there for vegging and flower have been working with this app. However, I am on vacation and away from the plants so I left my son in charge of things. He has Apple phone and a different app with different lux numbers for what it's worth.Jus wondering what is the app ur using an is it for android? Jus wondering cause im using the s10 phone an thought it was supposed to have a super good camera but the edges of my pics always go blurry so was thinking about getting a gud app. Then if tht dnt work eventually jus go an get a nice digital camera. I havnt wanted to enter any of the contests lately cause my camera jus doesnt do them justice. Plus i wana actually have a chance at winning lol.
