I've had this plant Phal. Speciosa var Alba for a couple of months now and somehow, it is surviving... thriving even ... But the sphagnum moss is going dark green with algae.
It's worse still on a bulb. propinquum I have kept pretty moist. Both plants seem happy and growing... but this green algae? has me concerned. Should I ignore it or am I flirting with a dangerous underlying condition?
