1.Dens just seem to take care of themselves(especially in s/h).Den kingianum even grew a keike in my unheated bedroom window(window is always open) & it flowered.Temps where freezing for a number of days & this never even phased it.
2.Catts. I have a number of species catts & they,ve done nowt in a year basically.
Zygo,s are a pain as well .I can flower them but i can,t keep leaves on them.Tried all different positions in the house(g/h & growroom) but i can,t find anywhere they like.
3.Psychopsis papilio.When the flowers drop off all i do is wait for 3 weeks & i get 2 more .
Hybrid Phals , Onc hybrids , Phrag hybrids & Den hybrids seem to flower pretty readily
