You got it

Ah. Orchard Supply Hardware? I had to google it lol.

LOL Osh is a home and garden store I guess they don't have it in Indiana...

I don't know what OSH is , but yeah, regular no-fertilizers-added potting soil. I used Fertilome Ultimate Mix, and it grows everything twice as fast as anything I've ever tried

Like...regular potting soil found at OSH?

Nuh uh. You could always trash the Aquasoil and do real soil instead

Too late to change that now

Potting soil. And not Aquasoil.

The Eleocharis is growing like crazy for me! What did you feed it?
