Tours at Hasel Tarim's Cravo greenhouse during Growtech Antalya:

Turkey: Retractable roof house productive 12 months a year growing lettuce, cucumber and tomatoes

When Hasel Tarim in Antalya Turkey purchased their retractable roof greenhouse, the plan was to use the greenhouse for a variety of trials and seed production. However, they did not want to be limited in what they could grow.... and when they could grow it which means that the greenhouse had to be capable of producing crops when temperatures ranged from -6C to 41C.

April 2013

When their tomato trials where finished earlier this year, Hasel Tarim decided to grow a crop of lettuce to generate some extra income since prices for lettuce are normally higher during this time of the year due to the reduced supply from conventional greenhouses.


June 2013

From April 28 till August 22, cucumbers, melons and peppers were produced. They increased plant density by 20% and had minimal losses due to foliar diseases even though temperatures reached almost 40C and the relative humidity reached 80%. They were able to reduce the size of their workforce since the workers were able to work productively the entire day due to the comfortable working conditions.

August 2013 +

In late August, cucumber seeds were planted and tomato young plants were transplanted at a density of 3.4 plants per square meter. Even though the air temperature was 39C and soil temperatures outside reached 60C, there were no losses of plants or flowers due to the heat and no plants have shown any symptoms of virus.

Transplanting tomatoes in 39 degrees Celcius:

In late October, several varieties of lettuce were also transplanted.
