We found in Google Books a scan of an interesting book from 1896, Greenhouse construction: a complete manual on the building, heating, ventilating and arrangement of greenhouses by Levi Rawson Taft, a professor of horticulture at Michigan Agricultural College. Below is an excerpt from the book on greenhouse history. While the information is dated, the book contains some interesting information and diagrams such as this illustration of the effect of glass at different angles. From Chapter 1, Greenhouse Construction, History of Greenhouses:
It is known that the old Romans were able to secure fresh fruits and vegetables, for their banquets, the year round by both retarding and accelerating their growth. As an indication of their skill, it is said that they even forced the cucumber. They possessed no elaborate structures for this purpose, but grew them in pits covered with large slabs of talc. Heat was obtained from decomposing manure, and by means of hot air flues. They are believed to have had peach and grape houses, and it is claimed by some, that hot water in bronze pipes was used to warm them.
In modem times the structures have undergone a gradual development, from houses containing no glass whatever, to the forcing house of to-day which is nearly ninety-five per cent. of glass. The first house of which we have any record was built by Solomon de Caus, at Heidelberg, Germany, about 1619. It was used to shelter over four hundred orange trees planted in the ground, during the winter, and consisted of wooden shutters placed over a span roof framework, so as to form the walls and roof. It was warmed by means of four large furnaces, and ventilated by opening small shutters in the sides and roof. In the spring the framework was taken down. This structure, in size, compared well with the greenhouses of to-day as it was two hundred and eighty feet long and thirty-two feet wide. On account of the expense of putting up and taking down this framework, and of keeping it in repair, it was replaced by a structure of freestone. This had an opaque roof, and the openings in the sides were closed with shutters during the winter.
What’s great about reading through these older volumes is to see what has changed and what remains true about an efficient, functional greenhouse. While they had no access to the modern materials such as the aluminum frames and insulated acrylic panels we use in our Sunglo Greenhouses, there is the same concern with durability, climate appropriateness, maximizing available sun and managing temperature. We hope you have fun reading it! And, if you decide not to build your own greenhouse out of wrought iron and glass, give us a call.
