Maximum
I 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?

Swapping lights during flowering
Do you guys think that swapping lights at the late flowering stage is going to harm my girls in any way? Been fortunate enough to be able to order myself a Viparspectra xs4000 to replace the v600. And as I understand it should be quite an upgrade. Thanks for any advice!

NEED SOME ADVICE! Change to LED from HPS? which ones are good for tent size? Which ones are good for good yields?
I've got a 4x4 tent with 8 seedlings in cups but will be in 11L pots. Currently I had a 600w HPS light but my ballast busted today. I have a back up CFL 150W not to mess up the light schedule. Thinking about changing to LED lights, I know it'll be cheaper but I want same yield...

How to measure lumens of a full spectrum LED light.
Since a lux meter only measures certain spectrums of light, how do I use a lux meter to determine the right height of my full spectrum grow light? I have it at the recommended distance but I have signs of light stress. Bleaching of some upper leaves. I moved it up 4 more inches?

How to dim a Sansi LED bulb
I have a 10W Sansi LED bulb for my grow, but I would like to be able to dim the light since, having limited space and needing to place it close to the plant, I'm having issues. (https://www.amazon.es/SANSI-Bombilla-Espectro-Completo-Invernadero/dp/B08P1RL7KC/ref=asc_df_B082PSBP68

Can I change my autoflowers light cycle withou reducing their yield significantly?
I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity). Even if I stress them, it would be better to not have mold than reducing the yield, right?

Use lamp while waiting the sun ?
Would it be worth it for me to go and buy a CFL bulb at a DIY store while I wait for the sun to come back? Or is it not good to have 2 different types of lighting (sun and cfl bulb)? And what kind of cfl bulb I could take?

Lux Meter Apps on Smartphones
What are your thoughts on Lux meter apps? The app on my Samsung Galaxy S10+ is showing 16,600 Lux at the tops of the seedlings, and converting that to a rough PPFD shows 222.55/umol/s/m². Reading more, 15k-45k Lux and 200-400 PPFD is good for early veg. What are your thoughts?
