Wow, that's an incredible collection! I think it's awesome that you're propagating the plants by seed too! And as far as the different varieties you have, I especially love the Anubias pynaertii, I would kill to have one of those! I'm going to have to add that to my list of plants to track down

What's your set-up like? Like what humidity do you keep the plants in? Are they grown inside some sort of inclosed space? I mean some of those Anubias are huge! What do you do with all your seedlings? Do you ever sell off some extra plants?
