This publication describes studies comparing different brands of commercial soilless mixes for growing healthy Arabidopsis plants. We recommend fine textured germination mixes such as Pro-Mix PGX and Metro Mix Redi-earth. This update removes the statement that Fafard mixes seemed unsuitable, as our more recent experience with their Super-fine Germination Mix has given excellent results.

This document is one entry in a series of questions and answers originally posted to the Purdue University Department of Horticulture & Landscape Architecture’s Plant Growth Facility Web site [http://www.hort.purdue.edu/hort/facilities/greenhouse/101exp.shtml] regarding best practices for Arabidopsis thaliana growth. Digital images showing treatment differences are included. A summary of recommendations; materials and methods description; and references list are available in separate documents.
