Does anyone here use this DLI calculator I found? https://growlightmeter.com/calculator/ It basically tells me exactly what PAR my plants should be receiving each week. Age of the plant and hours of light included. I would really like to know if anyone has strictly followed its week by week recommendations and how the grow went. I’m 3 days after germination following its 190 PAR recommendation for 18 on 6 off which is giving me a 12.3 mol/m²/d. This sounds AWSOME!
Determine the photoperiod and light intensity needed for an indoor LED light source to produce a given daily light integral.
I didn’t download the app. I’m using a Photobio PAR meter. I’m just using the calculator in the pic below. It’s calculating the exact PAR for maximum yield. I’m going to do what it says on this GG4 grow and see how it goes. I’m hopeful it’s going to help.
All I can say is for the auto chart: https://growlightmeter.com/lighting-requirements-of-cannabis-over-the-full-grow-cycle/ I think the values are MAX. According to the chart, mine should be on a DLI of 45. They cant handle much more than 20!
