Optimal Light Distance
Cyborg420started grow question 9 months ago
My plants are experiencing some heat stress and my light is currently at 28 inches distance and thinking to lower it but it could hurt more the plants since I just did some LST and topping. Is it okay to lower it down to like 25 inches? What is the best height distance? TY! :)

Your light is not 1000W, It looks to be something along the lines of a SF1000 and that is a 100W led light
growdiaries.com/diaries/177406-grow-journal-by-cyborg420/week/995373
You can move it down to 25" and it will be ok. even at 100%.
If you want you can update your diary with your lights model. Or make note of it in the diary its self. But I am 100% certain that light is not pulling 1000W from the wall.
One thing to note when growing autos. Its best not to do anything that is high stress, This includes topping or transplanting or over/under watering or feeding to much/strong concentrations.
all these things can negatively affect the root zone and cause the auto flower to go into early flower, putting a huge dint into your overhead for yield vs time invested.
Good Luck!

Hola si es una luz Led convencional te va a especificar 1000w pero no se utilizan esa cantidad real. Lo que tomaría en cuenta es el calor que puede llegar a desprender tu luz. Ponla a 28 pulgadas creo esta en lo parámetros adecuados de distancia y no dañara tu planta.

First of all your light is very strong. I hope you're not using it at 100% power (if possible).
With regards to light distance I prefer to position my light with regards to PPFD and DLI. I use a mobile app to check these called Photone. PPFD and DLI changes depending on which stage of your grow you're at With regards to your plant I would aim to keep my PPFD at around 600 and make sure to keep you DLI way under 40.
Don't get me wrong distance is also a factor because unfortunately lights don't just emit light, but heat as well. As long as you're 25 inches from your plant (with a light that powerful) you should be fine but every case is a bit different so adjust accoeding to your room temperatures as well.
Good luck with the rest of your grow. I hope you found this helpful

A 1000w LED lightning at 28 inches is already a bit too close

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

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?

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 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
