Yup, sure did. Lumens are an accepted (lighting industry-wide) term for more power output in (and around) the visible range. Strangely enough, they refer to the lumens (a quantity of color output) in the very same bulbs we use in our gardens, so I don't see the need to confuse the issue with unnecessary bullshit.

You seem to rely heavily on graphs...I want to see the graphs that show the spikes, and witness for myself that more lumens do not affect the infra red and uyltra violet wavelengths at all. I want to see that vertical step up into the visible range. Or does the graph show the bell-shaped sloping increase across nieghboring spectrums? In other words, if you add visible energy, it tends to affect the outer edges as well.

And correct me if I'm wrong, but don't more lumens equate to more light and deeper penetration anyway? Why offer full spectrum at all? Why not just stay at the infra red or ultra violet (non-visible to humans) wavelengths? Perhaps because growth isn't the only thing the plants need? Stuff like energy for maintaining disease resistance and healing, energy for bulking-up and storing nutrients and minerals, energy for proper metabolism...? Or are all these things provided in abundance solely by the unseen? How many chlorophyll's are there, and what is their function? I believe we already discussed in another thread, that chlorophyll B absorbs in the green-yellow range. (a hint why some of us like the full spectrum)

I do not mind being corrected if proven wrong, but if you wish to correct my postings, I suggest you add your knowledge and insight, not just a link and a rather uninformative statement. Otherwise, you look like a copy-n-paste lackey. And ya never know...I might be teachable.
Rusty Trichome Reviewed by Rusty Trichome on . Photo Period and Budding Problems Hey guys im new the forums and happy to find a good community. So i have some questions I have been growing and I have a sativa plant that is about 3 months growing now. What happened is i let it grow on 24 hours of light on flouresant bulbs 60w total. Then when i thought it was tall enough put it to 12 hours of light under those bulbs. After 2 months of vegitative growth and 1 month of flowering i did not get any flowers nor bud. I have many calyxs on the nodes between branch and stem but the Rating: 5
