I mix in 33% pertilite with my calloways. To be honest I'd prefer to start with good soil. And my roots aren't long enough to be entangled in all the soil.

I think it's good for me to take advantage now before it's too late.

I pulled the rapid rooter and the roots have grown outside of it but it's definitely not something that can't be managed. They're only about 1/4" - 1/2" long outside the rapid rooter. Still short and spunky and not entangled in the soil or with each other.

If I don't mind using another media, do you think this would be a better route than just using the calloways with even more pertilite.

I really want to do things "right". You know? More so I want to understand why things are "right". Which I am picking up, albeit slowly .
