Aquarium conversion

The water is also an irrigation. Firstly, capillary matting wicks from the bottom, of the tank, secondly, I have some small holes (intentially) in the pipe that leads to the top of the water fall that slowly drips water, to ensure the top also stays hydrated. So it is more than just humidity...

Ok, if it was me, and my plants arriving tomorrow, I wouldn't place new plants at once in a terrarium that is not working properly 100%, which means the quality of water included. If it was only to serve to a waterfall but the actual irrigation comes from another source maybe I won't worry that much. But no, I wouldn't risk letting those bubbles touch the plants.

Why you don't flush out that water completely and replace it?

I'll probably half fill the tank with water, let the pump pull it out and do it again.

Can't believe this is all from residue from my hands!

Would love to see an update!

This is the update.

Some white mildew has established as you can see. However, it mainly stayed at the bottom on the moss. Since removing the moss the whole tank has far less mould, so now I'm waiting for moss to spore at the bottom of the tank. It needs topping up every other day which is a pain.

I removed the masdevallia as it threw out loads of new leaves, but then my fan moved and the tank warmed up a little and it dropped three. The Masdie honestly just doesn't fit in there, neither did the jewel orchid. Both are still alive, just not in there. Both Lepanthes has gone crazy. The Coral hybrid has flowered a LOT, its currently not flowering much though. The Retrepia flowers the most though, and has a few spikes now, unfortunately no new leaves though. The Aerangis is putting its second new leaf our which is great too. The Dracula has 3-4, new leaves, I'm hoping for a spike soon. I plan on getting another small pleurothallis to put inside a rock at the back. I'm also still looking for a small, lower light bulbo to go in there but I haven't found anything yet.

The one thing I'd change is almost no organic matter, including aquarium wood. I wish I'd just used ohko stones only as the wood encouraged the mould and I think made everything worse early on.
