I have what i was told was a ventricosa cutting that i am trying to root. it has one small (1/4") root on it but is working on its second leaf. when would be a good time to plant it, when should i let the pitchers form, what would be the best mix to plant ti in? Im rooting it (the growing tip) with water in a dark beer bottle seems to be working but dont really know what the next step is and when to do it.
