I've not seen a comparison of such, but I'd look through the archives of Nursery Manager or American Nurseryman.

Would that be "Nursery Management" or "Nursery Mangement & Production" I couldn't find an online mention of "Nursery Manager"

The former has had 2 articles that mentioned either 'grow bags' or 'root control bags' One where it was mentioned in passing as being included as part of 'container grown' and one where it was part of a grower profile.

The later is one of these ad supported trade rags that doesn't seem to have an online version.

American Nurseryman had zero articles root control bags as a phrase, and 9 irrelevant articles that included all three words.

I've found lots of articles comparing RCB to pot production. As I track down authors, I'm asking them if they have compared the different root bag technologies.

Yeah, that's the one. They've changed the name a few times over the years (jeepers, I'm starting to sound like a geezer).

The only info I've gathered comes from the companies using them, which of course makes them sound better than sliced bread. I've never seen a side by side trial, or heard of one, or seen an article in any of the various pubs I get refer to such an experiment.

I guess I'd be looking for growers using RCB and be spending a little time asking them.

Or getting about ten from each supplier and setting up my own experiment.

Actually, that sounds like a good idea. And then you can publish your own article and the rest of the dolts like me will be quoting you.
