I bought these nice large plastic humidity top vent domes for my 5gal. pots.
I used to put a clear plastic cup over plant when getting them started.
I had two young plants that were growing but I put my new humidity domes over them and they loved it. They looked really good inside dome.
Then I thought they were big enough to remove the dome, and they wilted immediately.
I panicked and put the dome back on and opened the top vent half way.
I need help understanding what happened and how to save my plants , and how to use my domes?
