The Clear Sky

Commercial Greenhouse

The Clear Sky greenhouse delivers total growing flexibility with the patented Nex-Hood which allows the roof to partially open during inclement weather and for de-humidification.

Outstanding Growing Conditions:

  • The roof vent vertically opens to 85 degrees.
  • With individual motors you have zone opening ability allowing you total flexibility in cooling and venting.
  • Fewer obstructions than other full open roof style structures leading to higher light levels.
  • Total versatility for all crops at all stages.
  • You will get outdoor environment when the roofs are open and have the advantage over outdoor growing when you can also close the roof and protect your crops.
  • As a garden center you will give your customers the feeling of roaming through an outdoor garden on beautiful days and still provide a shopping area during inclement weather.
  • The roof can close in less than three minutes. 

Venting in Inclement Weather:

  • The patented Nex-Hood allows you partial roof opening in inclement weather.
  • Able to open vent with snow in the valley.

Strong:

  • The double tooth steel racks give you added strength at crucial stress points in windy conditions, and longer life than aluminum racks.
  • The unique in-house roof extrusion design gives you the needed strength and heavier extrusions for North American conditions.  Competitive European designs do not meet U.S. snow and wind loads.
  • The Clear Sky trusses are a flat ladder bar truss with smaller peaked frames for the vent openings. 
  • Our in-house licensed engineering staff has designed a structure whose quality is consistent with all Prospiant structures and is compatible with all Prospiant style structures.

Save Money and Maintenance:

  • Growers using the Clear Sky have experienced reduced need for chemical and growth regulators.
  • Growers have reduced operating costs by minimizing the need for use of cooling equipment.
