What is it about?
We carried out a meta-analysis of the effect of pot size on plant biomass, as well as a range of relevant physiological and morphological variables. We quantified how strong these changes with a doubling in pot size, and thus were able to rank the various responses

Why is it important?
Many controlled experiments in science use plants grown in pots. As pot size often constrains plant growth, it is good to understand what is the relation between the two, and what you can do to avoid a strong feedback of pot size on growth and physiology of your plants.
Perspectives
This is a very down-to-earth topic, but at the same time one which should have high relevance for scientists who want to do experiments, growers who want to optimise horticultural production, but also for anybody who has plants at home. And bonsai growers, of course!
