Anyone tried this?

I searched the archives and after reading through the first 5 pages of posts (there are 101 pages!), I determined they were probably 100% posts from the dirt crew.

I grew it once using flood & drain, but am now interested in using a multi-level, stacked NFT system with about 1/3 groton pellets in the bottom of the tubes. Asparagus grows from rhizomes and it's my thinking they will need some sort of structural support. That's why I'm planing on using the clay balls. I'm aware it's a slow-to-produce crop, but time is the one commodity I seem to have plenty of these days.

Anyone?
