I have a few spectra of osram light tube. Can anyone give a comment?
After done some digging and using of T5 I still don't like the result. I read
somewhere that plant uses 400-500nm of blue light and 650nm of red light.
Osram have a series that built especially for plant. The spectra below
Man! i like the way it make just for plant. THis is L36-77 Flora

However , locally this is not available.
I found a replacement. which is L36W 76
To me there is no much different between the two. What do you guys think?
To put things in prospective. I have here Metal halides OSram HQITS150WDL
and a HPS sodium vapour lamp.
which doesnt seem to fill the needs of plant! SO why pay $200 for something
don't work? Notice the blue spectra does not add up?
I have also thought of mixing a red light and blue light. Which also miss the
red wavelength by 50nm
However the blue seem to fill everything!
please comment
