I wanted some low ground cover plants for my aquarium so I ordered these seeds on Amazon:
Glossostigma Hemianthus Callitrichoides
They came in yesterday, April 10, 2018.
Lots and lots of little seeds. According to the instructions on the seller’s page, they should be planted on top of very wet growing medium which is maintained at 80°F and they should germinate in ten days. I have placed some seeds on extremely well-hydrated peat pellets. The water and growing medium are maintained at about 80°F.
I’ll post an update ten days from yesterday or when the seeds germinate, whichever comes first.
Update: April 15, 2018
Well, after only five days, the seeds have begun to germinate!
Update: May 5, 2018
Several people in a Facebook planted tank group have assured me that these seeds are definitely not what they were sold as and that it’s unlikely that any genuine aquatic plants are available as seed. So, I’m going to track the progress of these to see how they do. Apparently, they have high CO2 requirements and I’m not supplementing CO2 so, if they fail, that’s a plausible reason. The seeds were started in peat pellets and I have kept the expanded pellets intact. I put a few in my aquarium and some in a small planted bowl. I added a bit of gunk from my aquarium filter to the bowl. The bowl is kept on a north-west window. Here are some photos taken a few days after immersion.
UPDATE: June 7, 2018
It’s been about a month since the plants have been immersed in the aquarium and in the bowl. I added some pest snails to the bowl because I started seeing some algae on the glass. The bowl does get a little bit of direct sunlight later in the evening if the sky is clear. I occasionally change roughly 20% of the water in the bowl, using straight tap water. The plants seem to be doing well in both locations but the ones in the bowl have definitely outgrown the ones in the aquarium.
