Well, you won't be.
After this next exciting episode of;

Mary Wanna! Mary Wanna!

We're up to our hairy ears with lavarock here, brah.
Free for the taking!

But, like 'tron, it has no "holding capacity"
The drainage is near perfect.
For drip, drain to waste, E & F, it's useable.
But, for container growing, it's just not suitable.
Like 'tron, it takes up space better used, IMO, by more roots.

Coco's advantage?
Holds and serves nutes efficiently.
Is very difficult to overwater, and weighs almost nothing, dry.
So it easily holds 20X it's own weight of water.
Root infiltration is excellent.
When it's time to transplant, the rootball can be pulled from a container like a cork and dropped into a "cork" shaped hole in a larger container with no xplant shock at all!
Seriously, they don't even pout.

What turned me on to coco was a grower named Puffzter.
He's in a chair so weight was an issue.
Da bro grew some of the finest indoor buds ever, in coco.
If you can find his thread, he also created spreadsheets of his feeding schedule that are useful.

Well.
Will Mary Wanna wanna marry Gary?
Will Gary flee Mary, in a rubber boat, down the Estuary?
An' how 'bout dem Menehuni? Is dey ears all dat hairy?

For all da dirt on dirt what's not dirt.

Don't miss the next episode of MW! MW!

Beeg Aloha
Itty li'l 'zard.
