qu'elle est le plus important à prendre en compte le nombre de lux ou le PPFD/DLI
dataTwiiixstarted grow question 3 years ago
lux, ppfd et dli. en faisant j'ai réalisé qu'il était dur d'avoir un ppfd entre 500 et 1000 pour la phase plantule sans dépasser les fameux 7000lux on approchent plutôt les 25000lux si on veux atteindre le ppfd souhaitable pour cette phase. comment faite vous?

For a tiny seedling like that you only really need like 200-300ppfd so just lift your light higher.
With LED lux / ppfd / intensity works a bit differently.
Also, glass jars can act like a magnifying glass and burn your seedlings when used as domes, try plastic instead with a hole in it for air flow to keep them fresh :)

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

*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% & 55cm

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?

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. Ty

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

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

Light IntensityHi there! Last week I discovered that plants were very droopy. It was end of the day cycle so I dimmed the lights around 400 ppfd. Normally I would give easily 700-800 for 18 hours. Why is that happening now. Is it that my co2 ppm is very low? is it genetics?2 years ago
