If you have LED light, you definately should increase the light level to 400 ppfd! 150 is much to low.

150μmol/m².s is very low to me.
You can start increasing gradually to reach 400μmol/m².s

Looking at your pics I'd say the light height is decent where your at.

What are you checking with? How does the plant look? What's the light manufacturers recommendation?

- I have a greenhouse ceiling that covers 50% of the terrace
- should I grow the plants always under this ceiling, or if it is beneficial to expose the plants to direct sunlight?
- If so, how old the plant has to be to expose it to the sunlight? I don't want to burn my seedlingSetup. Lighting

Better temperature for early vegIn auto flower indoor, Early veg, is better have 18ºC/24ºC, or stai around 23°C during all the day. I have an Inkbird that I can set on 23, that is cool when is light off, it warm it up. But with light off it’s drop down temperature to 23.Setup. Lighting

Which strategy with auxiliary grow Leds ? 3x20w Leds -Thanks !Helps maturing but I wonder if buds are bigger. I used to put 3 extra lights 20 cm below canopy, leave many large leaves at the top and lollypop 30%. 30% is definitely not enough even with those 20w LEDS (50% is probably better). How do you use extra LEDS ? Where do you put them?Week 10
