Here's one of my Helen's Hybrid seedlings I grew from seed
I'd show you more pictures of all the different stages of growth it went through, including seed germination, but pictures are really hard to post on this forum.
It's indoors inside and contained in a warm humid grow enclosure under constant artificial light. It is surprisingly fast growing. That banana you see is only a little more than 2 months old. I got the seeds exactly 76 days ago, and then it took that seed 11 days wrapped in a moist paper towel inside a sealed plastic bag to begin to germinate.
