Found this article on how to get orchids to bloom thought it was interesting. They said that they need cooler temperatures to stimulate spike growth and flowering, idk if anyone has heard of that?

Yes- it’s a well known ‘trick’ but only with phalaenopsis orchids. It doesn’t work for all of them- it really depends on what genetic mishmosh your orchid has. Because grocery store phalaenopsis have been excessively hybridized, they are not going to all react like their species ancestors. If your orchid is in good health, has had a decent vegetative growth cycle, with new leaves and roots to support it, and is getting enough light, water, and fertilizer, you can try to jump start them into spike any time of year with a period of ‘cool down.’ The ones in my collection that reflect this trait really only need 2 to 3 weeks of nighttime temps that are a little cooler than daytime temps in my home. If it’s not comfortable for you or your family to lower the temperature to 60° at night, that’s understandable. In the fall when outside temperatures tend to reach 55-65 outside, I congregate those plants near a window and crack it overnight. I would never go below 55 though as it can damage your plants.
