Hola amigo, no sabemos si te servirá, nosotros usamos para tener un nocion o una idea, la app photone, no te aporta un resultado exacto pero te ayuda, la distancia tambien es importante, si necesitas una tabla orientativa nos lo puedes decir, saludos y feliz cultivo 💚🍀🌱🍀💚

These are my findings from experience. Maybe they’ll help you. (These values assume you are not using CO2) Seedling VPD Window: 0.6-1.0 PPFD: 200-250 Veg VPD Window: 0.8-1.2 PPFD Window: 400-600 Flower VPD Window: 1.2-1.6 VPD PPFD Window: Weeks 1-3: 600-800 Weeks 4-6: 800-1000 Weeks 7: 600-800 Weeks 8: 500-600

Hey RootsmanNL, at week 8 of veg the plant can almost certainly take more than you're giving it, but the dimmer % alone doesn't say much. What matters is the PPFD at the tops. Veg wants roughly 600 to 900 PPFD. At 18 hours that's a DLI of about 39 to 58. If you know what your light pulls from the wall, it's easy to estimate: watts x about 2.5 x 0.9, divided by the tent floor in square meters. Say a 450 W light in a 4x4 (1.49 m2): full power is about 680, so at 60% you'd be near 410, still under veg. So I'm with Nocone_Purple on going up in steps and watching the top leaves, something like 10% every few days until you're in that band. If the tops start folding up or bleaching, check the temperature at the tops first, then back off one step. Slow growth this late in veg can also just be roots filling the pot, so check that too.
