Lamp distance to canopy, dialing it in.

I usually use the manufacturer's recommendations on lamp distance from the top of the plants/canopy, but its different for some cultivars. Some need a little more distance at 100% some can take it a little closer than the recommendation. What signs do you look for to dial it in?

I use the photone app on my phone to get generalized readings. But signs from the plants will be drooping instead of praying if the lights too strong. But this isn't always accurate because they will droop for many reasons. Long term signs will be yellowing on the tops of the leaves and eventually necrosis. Too high heat from the light will cause leaf edges to raise

At first the leaves mood , leaves should be like praying for the light making like a V shape. Droopy leaves is a sign a photohinibition when you know that your water schedules and environment conditions are right. Then the temperature at canopy level, 21°C is the perfect temperature. And finally and diagnosis of the petioles leaves and leaves stems for purple color , meaning that your plant is burning magnesium and plant photosynthesis process is on a high level. Spotting lil tiny rust spots on the leaves when you know that your magnesium supplements is right, means that the symptoms are very advanced

Das erste Anzeichen, dass du zu viel Licht gibst, ist meist ein Aufstellen der Blattränder (Zacken). Wenn du das siehst, bekommt die Dame zu viel Licht. Ein leichter Pray-Mode zeigt oft den Sweetspot aus Licht, Temperatur und Luftfeuchtigkeit an. 👽
