Well. Most of you have seen my mix.
Ill repost,
Variant A
Variant B
They are based on gravel. Always, at least 40% of the potting media has to be gravel. I prefer it to be rough, but its not always the case.
The second ingredient I use is either peat, or humus(depending on what is available). Peat is the less dense of the 2 , so its upper limit is about 30-35% of the volume. If its humus(black top soil potted in bags), it ranges around 20% . Most of the soil im currently using has also sifted sand in it(larger particles, but nothing exceptionally large).
As an intermediate/additive, I add(and have added) perlite, baked clay, baked cat litter, crushed brick and etc. Sometime leca balls as topping, or additive if the plant is large.
That being said, plants are generally variable in their demands, so aloes and most crassulaceae are lenient towards more organic soils, thus have less gravel and more soil.
Epiphytic plants(cacti, hoyas, ceropegias, ) as well as orchids, tropicals( yuccas, dracaenas, plumeria), have also orchid bark added in their soils, to a varying degree. Same goes for the few bulbous plants ive own(but its yet to be fully tested).
