All healthy spider plants produce babies or spiderettes. If you want to encourage the production of spiderettes in your spider plant, so you can propagate them in water, give your spider plant a healthy environment to grow in. This means moderate to bright indirect sunlight, warm temperatures, and well-draining soil like indoor potting mix. Mist your spider plant occasionally and soon enough, you will see it flower. The white flowerings are what will eventually grow into tiny spider plant babies or spiderettes.
