Wow, swords, you seem to have this down to a science.
I don't really do much to mine.
I plant it in a mix of soil from my backyard, vermiculite, perlite, pea gravel, sand, and some orchid bark.
I did grow mine under an umbrella on my back porch that got about 5-6 hours of morning light but very little afternoon sunlight (as of a couple of days ago it is in my new greenhouse and gets diffused light all day).
In the winter I only water them once or twice and during the summer I water them about 1-2 times a week. I usually let them dry out for a few days. For me, they haven't been too picky as to how much water they receive.
I've never fertilized any of my succulents/cacti. I probably should, though.
My temperatures are the same as swords.
