Lighting an orchid closet - fluorescent or LED? Otherwise?

[fishmommy]

The thing I have been reading about LEDs that is interesting is you need to supply some stressor like a heat source and fan for robust plant growth.
I have seen sites that recommend against pure LED setups and instead recommend hybrid setups so that some heat is generated by the traditional lights.

It's so hard to tell on most of these plant lighting sites if the advice they are giving is really targeted at the needs of pot plants or is the advice more general. I hate that.
