at lot of the wendtii i have gotten came densly potted and i wanted to perserve a tight bunch so i did leave some of the wool, but removed anything on the outside of the roots. All 9 pots have been in the tank for months and are doin great! I was lucky to not really have any rot. Growth did seem to slow, and the leaves and steams kinda got a little skinny, but they are doin great now, especially since adding the co2! My Cryp Spiralis really died back pretty heavily, but it's getting a little out of control and is beautiful.. I might have some for sale soon.
