In our general plant biology course, students treat lettuce seeds with red light
and far red light for a seed germination experiment. They are working under
"safe" green light when adding water for seed imbibition, and while placing
seeds into the red and far red light boxes. My green light source is a heavy,
bulky wooden box with fluorescent bulbs and a green filter. I would like to
replace this green light source with a desk lamp and green fluorescent bulbs but
I don't know if the green fluorescent bulbs leak wavelengths of light other than
green. Can any one tell me if they have successfully use green fluorescent
bulbs for this experiment?
