Watching the first green bud peek through the brown dirt is a very exciting moment for kids of any age, parents too! For children old enough to appreciate the wonder of it all the experience is especially enriching. Testers reported how their children checked back every day eager to see if their plants would bloom inside this self contained terrarium. Patience is something that is not included and parents are going to have to dole that lesson out liberally as the excruciatingly long process of cactus growth drags on. Some testers suggested making it disappear for a while until the sprouting becomes more pronounced.
