When you are finished, all of your Setaria plants should be taken from the pots (soil and all) and placed into the red bag provided and taken back to the Donald Danforth Plant Science Center. These plants will be autoclaved and destroyed before discarding. We do not want any mutants to unintentionally enter wild populations. The pots and trays can be rinsed out, dried and boxed for return to the Danforth Center.
