Catasetum type orchids - flower spike development - lighting levels

[SouthPark]

Hi all!

I recall reading information about catasetum type orchid dormancy - where I assumed that truly dormant catasetum are not growing.

However, when these plants are in true 'dormancy' but is developing a flower spike, then obviously something is growing - ie. the flower spike.

So an orchid growing a flower spike isn't 'dormant' as such, right?

Also - anybody know if these kinds of orchids require regular lighting levels for flower spike development during 'dormancy'? Or could they grow their spike in say 'darkness' (followed by flowering in darkness)?

Thanks all!
