russrahlanswered grow question 4 years ago Typically the more light the better! Your plants can usually handle anything up to 65 DLI so as long as your under that, your good. A light meter on your phone will help with this. Korona is a good app and cheap, you just need to make a paper diffuser which is easy. Also watch your heat and humidity after installing it for a bit to see if anything changes for the bad. Cheers 💨
