I use playsand, and without root tabs do not have difficulties growing low light plants. If I were you, I'd go the super cheap route. I've heard mixing sand is usually not a good idea, becuase the sand will eventually mix together, and instead of having 2 distinct layers, you'll just have a mix of sand grains.

Which low light plants do you use? I figured a java fern would probably be good, as most ferns are plant that likes shade. Well, at least in outdoor gardening!
