Seed germination with Allgrow
Germination is a brief seed treatment, not the sustained exposure a growing plant receives, so higher concentrations apply here than on the crop pages. In our own germination trials Allgrow produced both more shoots and taller shoots than the control — in one, the shortest treated shoot exceeded the tallest untreated one.
