I bought a vft from Home Depot several months ago. I was going to repot it, but notice the substrate wasn't moss. The plant was growing on a big sponge the size and shape of the 3" pot. Needless to say, I was kinda shocked. Not wanting to fix what wasn't broke, i replanted in in a larger pot, sponge and all. Its been growing wonderfully. My question is, is sponge a suitable substrate? Will my vft be adversely affected if I continue to grow it in this sponge?
