Subject: CPs in troughs

The alkilinity of hypertufa would be a problem for many CPs, though you
could control leaching with a roofing tar or equivalent. I do have the
lime-loving Pinguicula vulgaris growing in a trough, inserted in holes in
a pumice boulder in a peat medium. The only drainage holes are small,
about 2 inches below the rim.

You can also construct trough-like wooden planters, coat the inside with
roof-tar, and avoid the lime problem.
