I have been debating weather I need to add some ventilation to the nano orchidarium… Most of the time RH is right at 100% and I am afraid I might get a problem with mold in the future. Right now the 80mm fan is set for 12V and is doing a great job, but once I get more orchids in there next week the air won’t circulate as freely.
So, today my dear husband helped me drill a ventilation hole in the lid right behind the fan. Check out this cool incense “smoke test”, it sure is pulling in air from the hole and RH has been holding at 90% so far. I am quite pleased.
