soo true.
That's where a light meter can come in handy.
Whether you are using LEDs or CFL or flo. lighting.

i have used a couple par38 led's on my terrarium and they look great. the light is very natural looking. they both total 19 watts and were 120 dollars each. they can grow anything. led's can grow plants easily. the wattage per gallon thing doesnt really work anymore. i would suggest just using quite a few 1-3 watt led's until it looks like your tank is pretty well lit up. i know even with my led's over my terrarium it doesnt look bright. they are meant for aquarium use and they do not spread as well through air as water. but they are much brighter as the water tones down the brightness.
