    Okay, my new terrarium is set-up. Its a 40-gallon tank with a T5 bulb. It's got some reflective stuff on the back wall. It's actually right in my room. I'm gonna try to hold the day temperature around 70F. The plants in it right now are (left to right) Judith Finn, Sanguinea, and some Capensis.

    Put some tin foil around it. Here's my terrarium.

    Maxx- None of those plants need a terarium that i know of. Also have you though about the dormancy period for the finn? You could probably just put them under a light and scratch the aquarium. But since you have it i guess you might as well use it now.

    Capensis- Do your plants get the right spectrums of light with those bulbs? And why do you have the front covered it is sad because now you cant look at your plants

    I know they don't need a terrarium, but I don't have anything else to put there right now and the Finn has never really pitchered so I wanted to see if increased light levels would help. Can you explain to me what you meant about the dormancy with the Finn?

At least, "the highest possible CRI" is an inappropriate criteria. CRI and color temperature are factors having to do with the average color the light puts out. Plants can use light coming from several ranges, so there isn't a single color that you're looking for.
    I'm actually thinking of switching from a full 6500K setup to adding 3 5000K's for a 50/50 mix.

    I've read on multiple sites, however, that higher CRI is better for plants as "100 CRI" = sunlight. I've read on this very forum that anything 75-100 is acceptable - the higher the better. Futher, on the plant light primer posted here, it reads "A 'perfect' light source would have a CRI of 100."

    Can anyone explain why high CRI is inappropriate for plants?

    -sigh- I have no idea if they are or not, someone threw away the original package of the bulb in the big lamp and my dad found a random in the black one. I figured with foil all around, it can get even better light, just incase. But I can still see through the top, though.
