Usually while peat is fine for germination, seedlings grow quite slow
in pure peat. I would repot the seedlimngs in a more open mix after
they've produced their first few real leaves. I use a mix consisting
of a special type of burned clay beads (3-4mm in diameter), peat and
styrofoam beads (4-5mm in diameter) 1:1:1. The same mix is fine for
young Heliamphora plants. Adult plants of both genera do better in
an open Orchid mix.
Bye,
Andreas
