Yes you can grow some of the aquatic plants in small containers and later add them to your tanks if that's what you mean ZackyBear. I have a lot of aquatic plant pieces in quarantine at the moment cluttering up my washroom counter in a bunch of jars and bowls right now lol.
It's best to look up the needs of the plant first though. Some more delicate plants might do best in a current, or need certain lighting even in a jar.
I popped in here too because of the name of the post. :D
I just got a foam planter basket that floats on top of a pond from a neighbor. She was going to throw it away. I grabbed it to put a juncus spiralis in it. (spiral rush, although I don't think I spelled the name right) I have a half whiskey barrel liner to float the basket in at the moment, although I may use a different container to float the foam basket in.
I need ideas on making a mini bog/water feature, I would like to use at least 1 juncus in the whiskey barrel liner. Soil ideas would be nice so I might even be able to keep a few minnows in the whiskey barrel liner with the plant/ plants. I don't want to poison any fish I might put in there with dirt that could fall out of the floating basket or regular pot I keep the plants in.
These are the things I have
The basket I have is about 6 inches and doesn't have a hard bottom I am guessing because its OLD. But it's just like this made entirely of foam with drain holes on the bottom.

pic of juncus spiralis, it gets to be about 14 inches. Mine are in 4 inch pots atm sitting in a birdbath to keep them wet LOL
I think this is the other juncus I picked up. If it's not, it's like this one, with strait leaves and little flowers coming out the sides of the leaves.
I figured someone here might be experienced with bog type plants. I would LOVE to use these baskets for fish tanks too but again I don't want to poison tanks with things that might leach through into the water.
