One last question (for now). I have this light meter and follow these readings to decide where to place my lights, do you concur with these numbers? I usually hang my lights ~18 inches above the grid in the bloom tent.
Seedling ~13,000 lux
Veg 50,000 lux (surpasses daily light integral)
Flower 80,000 lux (some colas get up to 90k+)
I picked up this helpful book via amazon: https://www.amazon.com/gp/product/1419732390/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
The light meter I use is: https://www.amazon.com/gp/product/B005A0ETXY/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

Humans experience light very differently from plants and with broad statements like "bright indirect light" floating around, it's quite easy to underestimate the intensity of light a plant actually receives.
If plants had eyes, they would roll them every time someone said the phrase, "thrives in low light". This is simply a a justification for using plants purely for decor. I prefer to say of the plant that it "starves gracefully at 50 foot-candles"
The last part tore me and pushed me to get more involved in understanding the needs of my fiddle.
I don't expect it to be perfect by any means, but is this website an ok tool to use for these purposes. https://www.waveformlighting.com/horticulture/convert-lux-to-ppfd-online-calculator
