Plants growing in
mixtures of Fafard #2 and arcillite had greater
mass than those grown in other media, as shown
in Figure 3, and in both cultivars, plants grown in
7:3 and 1:1 mixtures of Fafard #2: arcillite
showed significantly greater fresh (not shown)
and dry mass accumulation than those grown in
the 1:1 mixture of perlite: vermiculite.
