Not to bad.  There treated totally different than a houseplant.  I do not use the orchid mix they sell in stores.  It’s junk.   I have a company That I buy online from. They’ll even mix what you want . Actually this is the first time I’ve made my own mix. This is a different type of orchid than I normally grow.   Strictly rainwater for all my ladies. Even my outside ones. Lol 😊
