Hi there Mima..I just saw your thread. I also have a cycad, And from what I remember I only used regular cactus soil and I added some perlite. I did not measure how much I added... The plant was given to me by my aunt in Northridge, CA. Mine is in a plastic container..it is so slow growing anyways, so it takes awhile for it to outgrow the container it is in.. But I am battling some scales right now.
hard to get rid off...but so far plant is still alive, and it even made a baby on the side. My plant usually gives me new leaves around September.
