Results in the garden is what counts no matter how many university and NASA studies you point out to make or disprove your talking point. There are more than a couple people that have hit 2 GPW here and other forums also with high per sq/ft yields, with amazing quality too.
I never argued what people have done with them already. I argued the quality isn’t better because of the light.
And I have hit 1.4 in hand watered soil with a single ended hps before. If I had more photons I would have more yield.
I put up a link that says intensity still comes first before spectrum for results also. Was proven with hps vs mh tests at u of m.
The claims that don’t matter too much are forum and you tube and Instagram word of mouth. Too many variables and honesty is troubling in these venues. Who is going to put up a video log and then tell how poorly they did in mass audience?
I only count dense buds over the diameter of a quarter. Everything else is not weighed and goes in the trim/ small buds pile for edibles.
Can I do more with what I have. Probably in time with practice. If I counted the small and larfy stuff the numbers go way up.
Too many variables. And de hps is doing the same numbers and with cmh added has the best quality. Most intensity that way and best spectrum for flowering.
