Terrarium lighting control?

[orion141]

Hi All,

I have almost finished construction of my new 24x18x24 exoterra terrarium (purely for growing orchids). I have an LED hood from spectral designs. Currently I can manually dim the lights and have them at the same output over the whole photoperiod. I see that there is the option to buy controllers (for example Controller / Driver Combo (ELG-200) – Spectral Designs ) that can mimic natural light (dawn,dusk, etc). Do you all think these have any benefit in our orchid terrariums?

Thanks!
