How do you make Luanr dirt into soil?

simple, let microbes do it. They transform it here on earth let them do it there. Different microbes have different speeds and appetites. One in particular changes hardpan into soil in a rather quick 6-mo.

Check into BioDynamics--get your self past the mumbo jumbo and see the meat of the technique andyou will have all you need.

You really don't need much soil anyways; "soil" is just a live organism that transforms organic material and minerals into chelated products that plants can utilize. You can have a similar response by creating compost teas and use it to feed your plants that are planted in a gravel medium. In this case just have the medium in small enough chunks so that small budding plants can get roots around to support themselves.
