ok my new CF bulbs (u-shaped) give off a yellowish-green light :?
i thinking that this is not an ideal wavelength for plants...
do you think they will be ok?
2 20watt bulbs on a 10 gallon
is there a way to figure out the k #? it was not on the package...
being a science teacher i have some simple spectroscopes so i could determine the wavelengths that the light gives off... in manometers...
if i get this info could someone tell me it these will be good bulbs of if i wasted my money ordering them...
thanks
