Re: LED lighting
Again, all but the weakest lighting - such as LED strips not intended for plant growth - should work fine (but even some of those may work fine!). Most white LEDs have a somewhat full spectrum and the fixtures provide enough intensity. When you design a vivarium with over three vertical feet to penetrate, then would a more specific, intense source be needed. With bulb fixtures of the past and LEDs of today, I have always been able to grow most of the available tropical plants, as long as those that need greater lighting were positioned higher (nearer the lighting) and so on. I think in general most plants are less specific about light exposure than corals, but to compare the two, imagine that corals basically need full sun and most terrarium plants need shade. Not to say that tropicals need shade in a vivarium, but rather they require much less intense lighting, in general.
