If you are looking for an introduction to self-entertainment, I suggest that you buy a good light, mud with river sand, and then buy a CO2
(Need to be prompted is that when you buy grass, you can ask the business, the grass is dependent on the CO2 bottle, such as the red butterflies, you must have CO2 because my family does not have a friend to give me a week after the dissolved all the leaves,
My grass every day, more than 5 hours to turn on the light, usually grass and moss. I turn on the light for more than 5 hours a day, and the normal grasses and mosses grow quite well
Basically, the grasses that don't depend on CO2 and can grow well are: Ficus, Pepperwort, Horsetail, Anemone, Water Daisy, etc.
