Its a good conversation. You have the right attitute! Better than mine. Lol. I tend to argue. :)
I did both. Read for likely 1000’s of hours by now and have been growing for 5 years perpetually. Also have worked in the black market with commercial growers since the 80’s. Just never gardened before i got my medical card here in michigan.
When i joined the forums about 3 years ago i took some clones and tested all the main topics. Flushing to different light bulb types.
And all my results match the university agriculture info. For example. The university of michigan has been testing indoor grow lighting for years. They are now testing discreet colored diodes and specific growth.
Blue helps more with with compact leafy growth and continued plant health and red helps more with elongation and flowering.
The
hortilux super hps is said to have 25% added blue and did better for resin production in my room than a cheap plantmax hps.
When i added a blue mh to the super hps resin went up even more. But so did leafier plants and buds. And yield went down.
Cmh further reduced yield. The mh was a 600w. But also helped keep plants shorter and greener.
I think 2 600
hortilux hps and one phillips 315 3100k for a 4x8 area would be about perfect for flowering.
Or of course a similar ratio with led. Which i bet 3000k setups are close to.
