>>2664319>new pair of LEDs within that temperature range i guess because i doubt the cool-whites would help in the flower/bloom phaseI have seen many color temperatures thrown around, for vegetative growth anything from 4000K to 6500K and for flowering 2000K to 4000K but it is the general consensus that flowering and fruiting is better under lower color temperature.
If you are going to buy new lights I recommend ones that shine downwards or even better something with adjustable fixture.
This is my favorite bulb because it has segments that can be rotated and pivoted so it can be set to light exactly what I need and each segment outputs 1300 lumen, only downside it can't be dimmed, it might seem fragile but after two years they are still working well.
>Lighting systems is a rabbit hole, to be sureOh yeah, they absolutely are.
It really doesn't help that grow light producers will make articles why you need this specific wavelength only their light can deliver and you need to figure out if it's legit or just marketing bullshit.
>From what i gathered online so far, each plant should get between 200W to 300W of lightNowadays people use PPFD and DLI to measure how much light plant needs and receives, I have a smartphone app that uses light sensor to estimate those values, judging from results seems accurate enough.
This is the app I use with a list of plant PPFD DLI:
https://growlightmeter.com/light-requirements-for-plants/Keep in mind that distance from light source has a massive impact on total flux, double the distance and light flux becomes four times weaker following the inverse square law, this is why it's nice to be able to regulate light intensity and/or height over plants.
