As you have read, the first kind can hold moisture and drain well at a relatively neutral pH. Conversely, succulents prefer quick drainage and low moisture level. Orchids and other weak-rooted plants need solid structure and medium aeration.
For each type, there are many ingredients built up with four components like soil builders, aeration and drainage materials, fertility amendments, and water. Please carefully read the instructions on the elements and how to use a product properly to have the best results.
One more thing is adjusting pH. There is a proper soil pH level according to each plant. Roots need the right pH to absorb nutrients, so you can refer to the ways of adjusting pH: limestone for raising pH and sulfur to lower pH.
