THE GROWING ROOM IN COMMERCIAL HORTICULTURE

A.E. Canham
The production of a strong, healthy well-balanced plant depends very much on the correct choice of, and control over, the levels of a number of environmental factors. The most important one of these at any given time is that which is restricting growth or producing imbalance. All too often, especially during the four winter months - and perhaps even six - in Britain, this factor is light. At this time natural light is both poor and variable, resulting in a slow and unpredictable rate of growth.

If plants can be grown economically under controlled-environment conditions in which natural light is replaced by artificial light, then plant response will be more predictable, the timing of the crop more precise and management made easier.

Research carried out over the last ten years at the Electrical Research Station has shown that "growing rooms" are a practicable proposition. Commercial growers are now beginning to see their possible advantages and a number have already installed rooms to assess their merits for themselves under their own conditions.
