Yeah that would be good, I use plain potting soil. You have to mist once in a while and cover it with clear wrap.
A single 23 w is fine, it turns yellow if you have too much light. It is really easy to grow in dirt. Oh and to avoid it melting in water, do low light at first then high light with co2. I don't dose heavy until it carpets, ADA AS should still be good until it cycles.
How your water? Is it hard or soft? I like low ph, kh with med gh personally.
