Well, an update to how these are growing so far in this mix. All are growing nicely. Here is a pic of my Gran Nain on June 10th, all 9 inches of PStem in a 1 1/2 gallon pot.
Now, here it is today, August 30th with 29 inch PStem, in a 30 Gallon Smarpot, with 2 Sword Pups (Hard to see, but they are there).
So far, I would say a success!
