Interesting idea, I would love to have bottles of green in the winter time but I have one point to make...moss like all living things requires oxygen and I see that the jars are sealed, is the moss doing okay without air? or do you open them frequently enough that it is not an issue?
ps I like the caterpillar!
Good point. I'm definitely no expert on moss and just made these terrariums based on instructions I found online. I read somewhere that oxygen for some plants can come in the form of dissolved oxygen in water. I don't know how creditable that fact is or if that applies to moss too. I guess I'll just wait and see if my moss dies. Trial and error! heh
Okay, here's the science teacher in me coming out...
Plants, including moss, take in carbon dioxide and produce oxygen during the process of photosynthesis. This oxygen will be released into the air. When plants need to get energy for cell functions, they use the process of cellular respiration (which is the opposite process of photosynthesis and is what we do). So, they'll use up some of the oxygen they produce and produce carbon dioxide which they'll release into the air. In a closed environment, it's pretty self-sustaining. Plants produce more oxygen than they need, so they should be all set!
Okay, end of science lesson...quiz on Monday
