This 2 liter terrarium has been going for a few years now, but has really started taking off recently after putting it under new lights.
I’ve had the jewel orchid forever, and I can’t remember where it came from now. It wasn’t doing very well a few months ago and seemed to be getting eaten by something. After watching closely for a few days, I found a tiny snail that had been eating it. You can see some small brown spots on the leaves that seem to have been caused by the snail. After removing the snail, all the new leaves are perfect.
Riccia is a liverwort that is usually grown aquatic in tropical aquariums, but it can also grow terrestrially with a little effort. Getting it switched over took a little while, but with the right humidity and enough light, it’s pretty happy.
I had a tiny fern in this terrarium, but it slowly died off. There’s only one half dead frond left. I’m pretty sure it wasn’t getting enough light with the old lights. After getting new lights, all of these tiny green things started popping up all over the substrate. I’m pretty sure they’re gametophytes, a stage in the fern life cycle. Basically, fern sprouts.
I think I’m going to have to start removing riccia soon to stop it from smothering the young ferns. The timing should be pretty good for the viv I’m working on. Some riccia will work well in the water feature of that tank.
I’m not sure how long it’ll take to get to the next stage, but here’s a chart of the life cycle of ferns.
