...jar. A Christmas tree shaped jar ended up in my garage. It was probably meant to go to storge with the other three tonnes of Christmas periphernalia but didn't make it. I have decided to repurpose it for plant culture, specifically Aldrovanda.
Paul (pearldiver) got me started with this genus and helped me setup a culture that works with minimal fuss. No CO2 injection or other junk. Just some substrate (peat, sand, cat litter), clean water, some associated aquatic plants (Ultricularia, duckweed, etc.), and the Aldrovanda in a container. This has worked well for me for two years now in everything from five-gallon buckets to small Tupperware containers. I figure why not apply this culture to the Christmas tree jar.
The following photos show my new setup. First the jar.
Then I placed the substrate in. This time I am using 1:1 peat to diatomaceous earth.
I then flooded the media. I am going to leave it this way for a few days to saturate the media and (hopefully) keep it from floating. It will sink on it's own eventually anyway.
More pictures to follow as I add more water, the Utricularia, and the Aldro.
For the nay-sayers: here is a culture I have kept going for about a year-and-a-half without a water change. I just top it up as it evaporates.
Despite the copious algae, the Aldro keeps growing.
