Yer... here ya go... How to grow "moss" in a tank / enclosure thingy. Get a tank thingy...... add 2 inches of a 10-20mm clay gravel stuff like seachem Oxyx sand stuffs. Add some organic non nasty pesticide free coir peat stuffs or potting mix without all the evil stuff in it, around 2 inches or so. Add some lovely rocks.. or branches or whatevers.. Then find some moss (scrape it of the driveway .. buy it from an aquarium shop etc) Add moss and let the moss grow under a nice light ( most Aquarium bulbs will grow plants) for a few weeks until it turns nice N green: Add plants etc.... water a few times a week with a sprat bottle , check water by checking how wet the Gravel under the substrate is... easyness! Then do it on a bigger scale: The end..... Told ya I suck at "how too threads" plants are like anything.... Give them food / water and Ideal conditions and they grow N stuff.... Stuff stuff stuff etc... I like turtles.
