It does hold quite a bit of moisture,but it can also be used for some that like to be drier, it is really quite versatile! A lot depends on your growing conditions like any other medium. It is like everything else,you kind of have to go by trial and error. The hardest part is breaking it up to get the right sized pieces! Get a big hammer..lol...Jean

I use it with my Phals to take up an extra space in a pot and to add some weight to some pots that tend to tip over.
My only difficulty with lava rock is sticking the skewer inside the pot, so I have to rely more on watching glass fogging and moisture droplets. And yes, finding the right size!
Agree with the previous post - depends on what you're trying to achieve.
