I've bought this as a small seedling w/ 4 bulbs back in 2016. It grew into a 13 bulb handsome plant but still no flowers yet.
It is mounted on a plastic mesh cylinder filled with lava rocks, fiber cloths and chunk of pumice. It sits at the south-facing balcony along with other my orchids...I water it twice daily during the summer and once every two days during the winter months. Temperature is around 35°C day/29°C night during summer and 28°C day/15°C night during winter. From March through October I fertilize it weekly with diluted liquid fertilizer....Is there something I am doing wrong?
