Highpoint Nor’Easter Cannabis Greenhouse

All Greenhouses

Structure & Framework
  • Stamped engineering plans included with purchase to obtain your building permit.
  • 2 ft. bow spacing meets most snow and wind loads. If there are higher load requirements, we can add more structural components to increase loads.
  • Bows are 1.90”, 13 ga. Galvanized steel tubing with gothic design with 6:12 roof pitch to easily shed snow.
  • Truss assembly with every set of bows enhances strength of greenhouse and allows equipment such as lights to be mounted to framework.
  • 5 purlins and wind bracing included for rigidity.
  • Longer ground posts create a side wall height of about 6 feet before the curve begins on the greenhouse.
  • Strong 2” square steel framing for end walls that allow equipment to be mounted easily.

Doors & Covering

  • One set of 4’ wide x 7’ high double hung aluminum black-out doors allows for 8 ft. wide opening, and one 3’ wide x 7’ high single hung aluminum black-out door. Both doors lockable.
  • End walls are covered with light blocking polycarbonate. This is for blacking out your greenhouse on the end walls and maintaining an excellent seal for heat retention.
  • Two layers of 6 mil polyethylene film with 4 year warranty with all wire lock and inflation components included.
  • Inner layer of the film is IR anti-drip film which allows for heat retention at night in colder months and reduces condensation dripping in cooler months.
  • 2 rolls of greenhouse repair tape included.
