The Jersey Farmers Union wants the States of Jersey to allow farmers to sell off land that houses derelict greenhouses.
They say the industry has dwindled over the past couple of years.
But a Jersey grower has disputed that Jersey's greenhouse industry is finished.
Joel Richardson, managing director of J.R Jersey Horticulture, said selling off greenhouses was making life harder for growers wanting to expand.
He said he had been searching for an existing greenhouse site for his work but has failed because many farmers want to sell the land for housing instead.
Mr Richardson even considered moving the home grown Jersey business to Guernsey which is said to be against the development of greenhouse units into anything non horticultural.
John le Maistre, president of the Jersey Farmers Union, said the island's greenhouse produce industry suffered when the States withdrew funding.
He said this had left the island with several large areas covered with derelict glasshouses.
Mr le Maistre said the old buildings should be pulled down and housing developments encouraged instead.
He said it could be done in a sympathetic way, saving part of the land for farming use while building homes on the rest.
