I started at 24" from Canopy at 35%. After 1 week in Seedling stage I will be going up 5% power every 5 days. By the time they are all in flower since I am growing Autos the timing should work out perfect so the light will be at full power when they hit full flower. When I see that all plants are in full flower I will lower light to about 10" above canopy during flower to get over 1600 PPFD for the whole tent... This chart is a very good outlier of what your cannabis needs during it's growth stages. Around 300 PPFD for seedlings, 300-600 PPFD for Veg Stage and over 1600 PPFD for flowering stage.Same light for me, what distance and % are u on? Nice grow 8)
I use an app that just recently came out (Korona) is the name of the app I am using in the photo above, it is off by about 40 PPFD, so a reading of 40 PPFD above the app's reading should be right around the sweet spot.
