Off a cliff? Opinions?
I recently watched a video done by a long-time semi-hydro grower. He stated that he had learned that after years in semi-hydro, the orchids "go off a cliff" and start declining. He had issues with his collection and was converting his entire collection to organic. I'm left wondering if this is true, or if the growers "go off a cliff" in what is required to maintain orchids in semi-hydro. I'd be less that honest if I didn't say that flushing day is an onerous task, but not having to deal with decaying media, more frequent waterings, more frequent repots, etc. is a more than fair trade off in my opinion. Due to the nature of semi-hydro set ups, I cannot find a logical explanation for them all deciding they do not like it any more. Opinions?
