The Homejar Terrarium kit includes everything you need to build a terrarium except the jar. Perfect for if you have an old terrarium you'd like to bring new life to or an unusual excess of jars (I feel your pain) that you'd like to do something creative with.
 
The kit will include:
Tools (spray bottle, tweezers)
Substrate (soil and gravel)
A selection of plants (3 Plant plugs)
COSM's quick build and care guides
