Bests & Worsts Reviews from Amazon

There's nothing fancy here. The plastic equivalent of a mason jar, some potting soil, some seeds. The thing is, all the hard work of making a terrarium has been done for you: - Some ventilation holes punched out of the jar lid - Seed selection made, with seeds that grow quickly and are sized well (with respect to grown size) for the terrarium - Soil and pebbles clean and bright - etc. This lets kids get down to the fun part, i.e. actually putting everything together and then watering and watching, while skipping the parts of the project that might bore them if you did this from scratch (i.e. the adult having to track down a mason jar, matching lid, and then punch holes in it with a hammer and nail, for example). The final result is attractive, the seeds in our kit grew quickly (about 24 hours in we had sprouts) and well, and it was manageable for kids, who were able to take ownership of the project and feel proud of the results. It's cheap, it looks good, it works, and it teaches something about biology/botany and something about responsibility (e.g. watering to keep the plans growing). Easy win all around at this price.
