Lapides crescendi
Lapides crescendi vel calculi crescendi sunt substratum plantarum colendarum qui hydroculturae vel emendationi soli adhiberi possunt. Hoc substratum ex vitro per anacyclismum fit. Cui est plus spatii aeris et aquae retentarum quam perlites et lutum. Alia huius rei proprietas est plus aquae quam alvei oryzae fervefacti tenere. Lapides crescendi optio aggregato argillaceo expanso aequiperabilis videntur.
