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?

Light intensity for 2.5 week auto flower
Can anyone recommend how high and what percentage to run my light. The leaves have not been strongly perked up in a few days and I wonder if it's that the intensity of light is too high. I've been at 80% at around 14 inches. vipraspectra p600. Critical purple auto.

How to manage grow light height with plants of different sizes?
My grow light is suspended (offset from plants) about 10” from the canapy of my two LST’ed plants but only about 6” from my control plant (no LST). Everyone seems happy, and I am not noticing any burns or lack of growth (unless too close can stunt?). Should I rethink the setup?

Martian
Irregular light schedule.
I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her? My first thought is that it doesn’t matter much since she is an auto, however I know that plants love balanced environments.

Mars Hydro ts1000 info
Looking to upgrade my flower tent light to a Mars Hydro TS 1000, is this a good light for a 3x3 tent? It says coverage area 2.5x2.5. My tmlapy 1500w will be going in to the new veg tent. Also, is it safe to swap lights mid flower?

Marshydro FC oder FC-E
Is the higher price of the FC series worth it compared to the FC-E series? On paper, the difference seems rather marginal.
