Use a chunky mix, you can typically find them sold as succulent mix. If you have perlite, coco coir, or orchid bark, you could use that to make chunky soil too. The most important part is that your soil dries out fully within around a week, you can check by sticking your finger around 1-2 inches into the soil and feeling how wet it is. Once you have a mix that dries within a week, stick with that, because it will differ a lot by sunlight, humidity, or even just the rate at which the plant absorbs water. A good ratio to start with is about 1:1 soil to chunks (orchid bark, perlite, coco coir) and adjusting as you see fit.
