I have a container of gesneriad seedlings that came from a mixed packet. The seeds included Achimenes erecta, Primulina tamiana, Nematanthus albus, Columnea linearis, Columnea hybrids, Nautilocalyx mellitifolius, Sinningia speciosa, Chirita viola, Chirita sp. from Phuket, mixed mini Sinningia hybrids, and mixed Streptocarpus hybrids. I had been growing them on a kitchen counter top with natural light, but they weren't getting enough light, and it wasn't the most convenient location. I moved them and have a 17W T8 aquarium lamp about 12" above the seedlings with a light cycle of 12 hours on, 12 off. The seedlings are just now beginning to put out true leaves. Do the lighting parameters sound ok, and if not, what would you change? I've grown a lot of gessies, but never from seed. New ground here.
