Oh.... I'm not so sure about the 12" bit. Taller pots require more frequent watering as the wicking action from the res seems to be challenged until the roots fill in. I ran some 24" tubes this year. I want to get a monster outdoor auto out of one.
As a general rule, I like to kick any tire I can. Pot size is a frequent target of my kicking.
Having said all that, the 12" height does simplify life. If one wants a simple grow (and I do), the 12" form is juuuuuust right. Of course, it's still only 6L of medium, and one doesn't generally grow monsters in any 6L format. I get around 2-3 oz off a well grown girl and the plants finish off under 3' tall (above the pot).
How's ur headroom?
