Little science-fiction gardens. This is what we imagine gardening in space to look like - living creatures growing in psychedelic mediums. Dirt is so passé. The Plantarium Garden Lab Kit is a mini modern greenhouse. Plants grow in a tinted gel, so kids can see what happens to their seeds from the very earliest root sprouts. The kit comes with all three planters, gel medium, seeds, and peat and pots for later transplanting. At just 4 1/2" high, the growing time from ungerminated seed to 'time to transplant' is short enough to keep a kid's attention span, and these are sleek enough for a modern kitchen window. $30.00 for the set; no idea what 3 plants the included seeds grow up to be.
