*FC-E4800 Hanging Distance*1st grow -4x4 with 480w Fc-e4800 in early veg (auto) but I am very confused on light distance and dimmer %. Apart from recommended distances, can someone point me to how I can establish the correct height and dimming % required based in the grow cycle? Currently at 30% & 55cmSetup. Lighting

Light spectrum during veg and bloom periodsI have 2 1000w full spectrum lights. Each light has 2 switches-a veg button and a bloom button. This gives 3 settings for the lights-veg only, bloom only and both lights on at the same time. What settings should I use during Veg and during flower and how close should I hang them?Setup. Lighting

ViparSpectra P600 or P1000?I'm just starting with a small setup (40x40x100cm tent), only one small plant at the time, but want to be able to grow proper quality in long-term. I suppose the biggest difference between the two lights is the 930 vs 1006 umol/m2/s? Any advise appreciated!Setup. Lighting

Changing lights for auto flowerAt the beginning the light schedule was 18/6 after 2 weeks I changed it to 24hrs because the light was too weak (10w) I now got different stronger lights (600w)(finally arrived) With the stronger lights can I change it back to 18/6 ? It's autoflower.🤔🤔Week 3

Maximum / Optimal Lux or FC for LEDs and checking readingsI have a Viaspectra P2500 which is a bit big for my tent but I figured I could dim it and have when I upgrade my tent.
I think I am burning my plants though so I am wondering what the maximum and optimal Lux/FC is for LEDs. I have the Light Meter LM-3200 app with diffuser. TySetup. Lighting

MaximumI have the LM-3100 Light Meter app on my iPhone using a piece of paper to diffuse like it instructs but I am not sure what the optimal Lux/FC should be.
Specifically for LED lights, it is confusing. I have a viaspectra P2590z what’s the max/optimal light?Setup. Lighting
