Re: lava ¶
Hi Dirk. Certainly lava is a good choice, because it contain a lot of useful minerals. But lava from different volcanoes may have different composition, so one type of plants will grow better than the other one. I think that much better is to use lava in a form of some base or initial compound, in which can be added certain number of micro- and macro-elements that will make it equally good for variety of plants.
