My
worth;
If you should decide to put it in LECA, or any other medium, whatever you plant it in should be a relative in size to the plant, ie. smaller plant = smaller medium; the same with pots. If the medium or the pot looks too big, then it is.
.
You might sift through the LECA to see if there are smaller pieces you can use, or break some up, but a very small plant should be in something smaller than 3/4 inch I believe. But a 3-4 inch Neo should be able to handle such as this, dependent on the size of the root mass.
I love the Fuuran pots myself and am moving mine onto one once the spring growth appears. I have been advised to wait until March to replant.
I have no experience in S/H and will not comment on it. Sorry about the Phaius!
