Yarmouth-based Estabrook’s nursery and garden centers has completed a state-of-the-art commercial greenhouse in Pownal, which at 55,000 square feet is nearly as large as a football field.
Tom Estabrook told Mainebiz that the new facility doubles the company’s production capacity while reducing the amount of time required to grow plants to the ready-for-market size by 30%.
All systems are computer controlled. Mechanized curtains close at night to hold in heat. Radiant heat lines the floor, and piping along the walls and glass roof provide warmth year-round, from a 30,000-gallon propane tank.
Despite the facility’s expansive size, Estabrook said fuel consumption here will be less than in the company’s Yarmouth location, where there are 27 traditional greenhouses covering 45,000 square feet.
Scarborough-based CWS Architects provided design expertise and Sevee & Maher Engineers, headquartered in Cumberland, handled sitework. The greenhouse was supplied and built onsite by the Netherlands-based company, Attko, which has a U.S. facility in Powder Springs, Ga.
Plans call for eventual expansion on the 16 acres in Pownal to a total of 205,000 square feet of greenhouse space over an anticipated four-phase timetable.
