Ok, some specifics. I started 3 pots of these. #1 is in my paludarium, temps vary from 65F-75F, humidity from 50%-90%, pot receives low light, about what a Phalaenopsis likes. Nothing there yet.#2 is in a warm room full of aquaria, temps stable around 75F, humidity stable around 70%, pot sits about 2" below a T12 fluorescent that needs replaced BADLY. Nothing there yet.#3 is in a greenhouse at work, temps vary from 50F-85F, although in the last few weeks it hasn't gotten over 75F. No humidity gauge, but it's definitely sticky in there. Pot is under moderately bright light, a Nep miranda a few feet away grows nicely with good color on the pitchers. That's where a single seedling was noticed this morning. Hope this info helps!
