The greenhouse threat you can’t see — and how Felix Instruments is helping growers fight it

Growers are being urged to watch the levels of ethylene gas in greenhouses because too much of it can hurt plant yield and quality. Ethylene is a natural plant hormone that — at low levels — helps with processes like germination and flowering, but in enclosed greenhouse spaces it can build up and become harmful when concentrations rise above about 0.020 parts per million.

In tight or poorly ventilated greenhouses, ethylene can accumulate well above safe levels because both plants and equipment can release the gas. High concentrations have been linked to stunted growth, distorted leaves, flower and fruit abnormalities, and lower overall yields, especially in sensitive vegetables.

The risk depends on plant species, temperature, how long the gas stays in the air and the stage of plant development — young plants and flowering crops tend to be most vulnerable. Growers are advised to improve ventilation, maintain heaters and remove decaying plant material to reduce ethylene buildup.

Even though ethylene is invisible and odourless, its impact on plant health is very real. By making it possible to measure what cannot be seen, Felix Instruments gives growers a way to stay ahead of the problem — turning guesswork into clear data and helping greenhouses protect both crop quality and long-term yields before damage occurs. Greenhouse operators looking to protect crop quality can can send their inquiry for a free consultation and trials.
