It's been just under a week and the new growth points have matured quite a bit:
I now count 17 individual tips. Most of these are over two inches. For scale, the tip of the new leaf coming out on the largest one here is five inches from the media. I'm moving this pot to a different light set to give it more clearance and a bit more light.
The last two sections of the original plant have changed very little in the greenhouse. After inspecting and clearing out dead material, I decided to repot one of them, similar to what I did with the one above last fall. In these two pictures you can see the large (3") calloused tissue that has grown outward from the original corm, with little plantlets all around the edges:
This will be put under lights next to the first pot. As before, the original roots are planted in the good compost/nursery media that I usually use for bananas. Besides the delay (which I think may have enlarged the new-growth-point-producing tissue) the only differences are that the top media is a 50% coir mix that I've been experimenting with for germination tests this spring, and I've added a bit more of it so that the callous is deeper (~1 - 1.5" below the surface, as opposed to 1/2" on the other one). I'm hoping that the light-weight media will still allow enough oxygen to the growth tissue, while helping with root initiation, which will be the next challenge for the first pot.
