Forgot my lime

[solid7]

Has anybody here every forgot to include the lime to their earthtainer/earthbox/etc, and added it after the fact? Maybe by some clever means? (a liquid suspension, perhaps)

I use a little different method that involves some compost (yeah, I know, rule breaker) that feeds and buffers. The plants look absolutely fantastic. I just don't want any surprises later.

Thank you in advance.
