They look great to me. I would be inclined to grow them a bit shadier. I don't know that they need the standing-water treatment if they get daily watering, but it's another way to keep them hydrated. Alas, I have not been able to grow this species, since they really do want a winter chill. (Hab. dentata does OK outside for me, doesn't seem to need to be cold but likes cool, and Hab. medusa is a warm-grower in the greenhouse, starting to really get going)
