Yeah, that's good enough for them to thrive for a while until the ingredients start to break down over time. Do 50% perlite and 50% soil or you can even do more perlite than that. But this mixture does not qualify as a gritty mix. Are you wanting to do a gritty mix?

Yes

Spike I posted on your other questions some ingredients you can use. See what you can get in your area and we all can advise you what would be the best route

So this will be fine for know? Noah

It's better than REGULAR STORE BOUGHT soil but it's not a gritty soil.

NOT a gritty mix, but it is better than what's usually used by nurseries/big box stores, and usually good enough if you just hold off the watering urge and if you're okay with more frequent repotting,

If you go with the 50/50 perlite/soil mix, make sure to top dress with rocks so perlite can stay put.

50 % perlite ammended with 50% bag of soil the operative word is 'thrive'>.

The 'gritty mix' takes advantage of coarse and gritty ingredients to make a soil that holds good amounts of moisture inside of and on the surface of soil particles, but little or no water between soil particles. It's the water that exists between soil particles that robs soil of aeration and causes all the problems. Mixes of 50% potting soil and perlite are still going to support perched water at the same ht as the soil w/o perlite would. Particle size is a significant consideration when building soils that work for you, instead of against you.

Al's gritty mix saved my succulents. I live in a humid area with very soggy summers. Rotting plants are a very real phenom here.

This is some of soil I had used initially, MG cactus mix and perlite. You can see that I didn't skimp on the perlite. This particular picture is of the soil that had not been watered in over 2 weeks. It is very damp.

My plants did "ok" for about 9 months, then all were showing signs of distress. Most had poor root systems. I was really astounded by the recovery after repotting in the gritty mix and I have never looked back.

So I guess I am advising you that perlite and soil are an adequate temporary mix, but be prepared to repot into a better medium. Al gives great advice on this.
