Hello Growing....I don't use gritty mix, you can search in this forum, and plenty of info for you.
You live in zone 9b, your climate is great for your adenium.

Please post pictures soon.

Hi Growing,
Yes there is a lot of info on this site. I know that Al has mentioned the amount of lime/gypsum to add to mix. I think if you search the site under this heading, you should come across it.
I do not screen most of my ingredients other than the bark if there is pulverized/fine particles in it.
In your climate you can have a bit more water retaining material in your mix.
For the warm growing season atleast, not the rainy time.
I would go with the 1.1.1 mix.

Hello from Jax Question? are you growing outside or inside? Drainage is important. I use a gritty mix as I need to drain the rain fast sometimes.

Ace for potting mix 40 lb X2
Ace pine fines big bag 1/2 bag
perlite large bag 1/2 bag
Home Depot step #1 paver (outside. It is an awesome grit) to taste
I use a composter to mix. Wheel barrow works well to.

Make sure there are multi holes in the bottom for drainage.

These plants are addictive. Hi I'm Paula

What area of Florida?

Hi Growing,

I'm south of you in Miami, and use gritty 1:1:1. For small pots you can use granite, bark from pet store and turface (or buy napa floor dry), for bigger replace granite with perlite so pots aren't crazy heavy. I'm chronically under watering my plants in gritty but on the other side newer had issue with to much water during raining season ;)! If you remember to feed and water in this heat your plants will be happy! Unless you keep planter in large saucer filled with water it's next to impossible to over water in gritty mix.
