Hi my name is Wes on behalf of Expert Village.com and in this video segment I am going to show you what kind of base layer to use when you are setting up your tropical plants terrarium. If you want to know more about terrariums and tropical plants, you can visit us at equilibriocarnivorousplants.com. Now one important thing to know when you are setting up a base layer for your terrarium is to know what kind of options you have. I like to use these clay beads for several reasons. One they are very light weight and provide a perfect drainage for your tropical plant terrariums. Another thing you can use is gravel or charcoal. The disadvantage of using gravel although it does provide a good drainage is that it can be very heavy. This can be a problem when you are trying to transport your terrarium from one area to another. Another disadvantage of using charcoal is that it can be really messy even though it does dispose of and recycle a lot of nutrients. Now one thing that you do have to know even though you are using this type of base substrate is that you are going to have to replace it after 5 or 10 years. It does have a very long life span but eventually you will have to replace the base layer.
