Light height and intensity
Hello all. Recently I upgraded my lights to 2 mars tsw 2000. I've noticed my plants are growing slowly compared to everyone else's. I have it set at 24 inches 25%. However a mars hydro admin posted 12 inches 75% during veg? Isn't that like 1500 ppfd? I'm so confused.

Light distance and power with a 205W Sanlight LED
Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !

New update got my new grow light dialed in.. And the nutes helped a lot seen more growth in one day than I had in the last 23 days! I am worried that if I place the light at the recommended height (6”) that would be too much so I’m running the lights at 50% power and at 12” away

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?

Mars Hydro TS1000 hanging height
People with experience using the MH TS1000, between 24"-30" at 25% seems like a reasonable height to put my light over the plants in initial vegetative state at my 2x2ft tent? Thank you! :)

I have a 2x4 tent I think I’m going to flower 2 plants in in a SCROG in 5 gallon pots. I have 2 Mars Hydro TSW 2000s (300W each), is this going to be overkill on lighting?

How much light - PPFD - without CO2?
How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.
