Actually, my brother grows fully organic in containers quite successfully and writes about it in books and magazines. I think Ray grows organically in his Earthtainers so I know its possible. But to me, growing organically, in an Earthbox seems like an oximoron. The wicking depends on the peat or other sterile potting mix and the organics depend on a living mini herd that would die off in a sterile enviornment. To the extent that you start adding compost or manures, you encourage a soggy, non wicking situation.
