More light into the greenhouse in three steps

Submitted by Elsewhere on 2020-Aug-13 Thu 10:05

An old growers' saying has it that 1% more light yields 1% higher production. Scientists have since shown that this is in fact a bit more nuanced: depending on the crop this varies from 0.5% to 1.25%. However, the principle remains the same; during a large part of the year all of the sunlight can…
