Hypnum moss take care way similar with wichurae moss, but hypnum moss need more air flow. It doesnt like in always close container with hot, wet and no air flow.
At Moss Design Gallery we use grow lights for all of our moss products, ensure the lights are between 6,500k - 7,000k in color for 10 hours a day OR you can use a east facing window! Make sure you don't leave the grow lights on all the time, the moss needs to rest!
