. . . does your formula need to be adjusted for "containers" of the size that I have?

No it doesn't, as long as the containers are elevated like yours. If those containers were on the ground, they would simply be raised beds, and because of the wicking effect of the soil below the beds, you could grow very successfully in a much finer soil.

Pine bark fines are finely processed pine bark - usually partially composted. I prefer this for my garden display containers & veggies - anything I intend to last for only a year, though it would probably be structurally fine for a second consecutive growth cycle. You can see an example of it at the top of the image I'm posting. I'll post another image of other bark just below this post. I can't figure out how to post more than one image in a post. If anyone knows how, I would appreciate a heads-up and some instruction?
