Will plants grow under fluorescent lites?

Plants (at least leafy plants, such as houseplants) seem to like fluorescent light just fine. The trouble is, you're NOT going to make get fluorescent lighting as bright as direct sunlight. Not a problem for many houseplants, but cultivating a typical arable outdoor plant, say a potato plant, under fluorescent lights won't work unless you use a LOT of lights / reflectors / mirrors / other clever tricks. Too little light will make plants spindly. A lack of blue light will do that too. So, if you are unsure if you are using enough light, make sure you at least use daylight tubes. Ask you supplier for "triphospor lights with high color temperature". These give a lot of light with enough blue rays.
