I’ve tried a few of these but had problems overwintering little plants. Last year or year before I bought a moderately adult plant from Marlow orchids at the SEPOS show, and remembered to water a little last month and this year it’s growing like crazy! Completely on a windowsill and with lights once the spike started coming up. Have to keep turning it by the window and raising the lights as it gets taller. Just opened a few days ago
