I've really been wanting a RCS bowl for a while now... I want to plant it and all. Would this tank work? If I did, would it be fine without a heater and without a light? I have a south facing dorm window I can put it in that I grow succulents on just fine, would that grow low light plants without a problem? If so, what plants would work? Mabye some anubias var petite or S. Repens? What substrate would I use? Would sand work, or should I do a Walstad type tank, with soil capped with sand?
