Practices and products to control algae in greenhouses

The University of Connecticut has published a review about the biology of algae and practices and products to control it in greenhouses. 

Algae is one of the most common problems in greenhouses. Algae is present in facilities producing ornamentals, vegetables, or cannabis. It grows even in the tightest production systems like indoor farming. Algae grows in organic surfaces (e.g. peat or bark substrates, foliage), hard surfaces (e.g. concrete floors or tanks, expanded metal, emitters, pots), inorganic substrates (e.g. rockwool, cooling pads), and solutions (e.g. water sources, nutrient solutions).

Algae is a nuisance in controlled environment agriculture. Unlike other pests, diseases, and weeds in the greenhouse, algae is one of those problems that is rarely studied – perhaps because the economic injury level on crops is low. Algae can also be a worker hazard when it accumulates on walking areas. The publication provides recommendations on controlling algae in greenhouses.
