Here's how I grow my orchids
Both windows facing south but the room with the pallet is brighter as it doesn't have a huge olive tree in front of it... Lol
Pallet painted and screwed wheels so I can move it easily if needed.
Then the rest are on an IKEA lack table, and the real tall ones on short stool and crate with a marble piece that was a left over from I don't know what!
Moved the vanda to the balcony facing east and south hopefully it will bloom (is growing roots atm, never bloomed for me)
Note that the brassia, jungle monarch and sharry baby yellow flash were already in bloom when I got them so I'm not taking any credit for it!
