Greenhouse Roof Replacement Hilo Repository Questions and Answers 001

Q1. Site visit and existing conditions & Roof dimensions and quantities:

Could you provide photographs, Greenhouse Manufacturer, dimensions/measurements and the panel count? I could not find this information in the documentation.
