In colder climates with a Sept-June schedule Micro Toms make a good mater to grow with a class. They don't need a huge amount of light and they only grow 5-8" tall so can be grown on the windowsill in 4" pots. The fruit taste isn't great (its really a decoration tomato) but the process is fun. There is a recipe online somewhere for making jam with tomatoes and raspberry jello so they could be processed in class into that type of jam making the planting/harvest/processing portion of the unit complete. Just my 2 cents, lol! Pete
