Research paper re moving plant lights.
Some folks advocate using setups where the grow lights are mechanically moving. This idea makes for lively debate. The issue is moot for almost of us because it is so complicated and/or expensive to implement. However, if you are still curious about moving plant lights, this research paper might interest you. Campanula plants under moving lights had less increase in biomass and thinner leaves. I could only read the abstract because you have to pay (dearly) for the full article.
Anyone have references that contradict?
BTW - the Actahort site is a great place to find lots of horticultural research article abstracts. I enjoyed looking over the ones relevant to plant lighting.
