Hermafrodite qeustion

Yes you can make seeds. If you’re find with always having intersex plants from those seeds.. go for it but this will be perpetuated down the line of seeds. I recommend against it but if you don’t mind seeds in canna and a bit lower quality- go for it

Kill it. You don't want anything to do with seeds that want to hermi.

If you isolate the hermaphrodite plant in a separate tent and let it flower, it's possible to obtain seeds. However, be cautious, as hermaphrodite plants can pass on the tendency to produce both male and female flowers, increasing the risk of hermaphroditism in future generations. If you're seeking feminized seeds, it's generally recommended to use reliable breeding techniques or purchase feminized seeds from reputable sources to ensure genetic stability. Introducing an additional female plant for pollination can also be done, but it's important to carefully manage the process to avoid unintended pollination of other plants in your grow space.
