Too much light ?
So started my second run and got everything dialed in but this time I’m running with spf-1000D and the normal spf-1000 is that too much light for the plants that would slow them down ? Together the lights should be around 200w

Not enough light? Help?
I think my flower is not getting enough light. How can I make do with the light on my balcony (that only hits the plant from the side for about 6 hours a day). Any tips or tricks for increasing yields in my "lightless" situation? (Growlights are out of the equasion due to space)

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?

Thoughts, good idea or bad idea?
I got an idea from when I was pruning pecan trees growing up. If I install small LED lights directly inside each "window" or "pocket" will that improve total light and production, or will I just burn the plants?

Should I switch to flowering now?
The height of my growbox is 120cm (4 feet) and I'm afraid that sativa can grow taller than that.
