Mas'd terrarium

[King of diamonds]

This is my first time growing orchids and I am still working out what is involved. I have 3 so far: 2 Masdevallia (barleana and rolfeana) and a dracula erythrachaete.


I have been reading up and these are mountain orchids. My room is south facing and around 18 degrees pretty much 24 hours with little airflow so I will be giving the plants some assistance to get the right conditions.

I plan to increase humidity by putting them into a small glass case about 50cm long, 30cm wide and 40 cm high.
Aparently they like good air flow, will an 8cm pc fan be sufficient? I can put in more then one.

My room doesn't get cold so heating likely won't be an issue but as they are mountain plants will I need to cool them at night? my room stays the almost same temp at night as during the day.

At the moment they are sitting in a makeshift humidity tray out of direct sunlight while I sort out a long term solution. What medium would be best? I was thinking orchid potting mix with a layer of spagnum moss on top but I notice that the guy I bought them off had them planted directly in moss with no potting mix.


All healthy small plants with around 6 leaves (around 10cm long) on the mas'd and about 3cm long on the drac. Not sure how old they are but aparently flowering size (according to the seller).
