Fastening Nails

For fastening the treated lumber erected vertically to the horizontal runners and roofing poles. Can be 2, 3, and 4 inch iron or aluminium nails.

Gutters

They are meant to collect and pour water that could possibly stagnate on the roofing polythene film.

Treated Wooden Poles

They make up the entire structure of the greenhouse. The required pieces are:

Vertical poles or wooden stanchions approx 6ft height and 3 cm width
Wooden timber poles or bamboo sticks for roofing.
Frames for wall support
Thin frames for crop support approx 2

Conditions for a Stable Wooden Greenhouse

A good water storage tank or source
Presence of Suitable irrigation system

Features of Wooden Green houses

In regions or places where night temperatures fall below the optimum temperature, the vents should be efficient to be open during the day and closed during the night.
The stanchions in wooden greenhouses are typically made of wooden poles or timber. However, in some cases, a steel tube holds wooden frames together on the horizontal framework that lies on top of wooden stanchions.
Closable/ rolling up ventilation can be built in such places. This type of ventilation has a polythene film and a mesh of insect net or shade net material on the inside.
The ventilation needs to be reinforced with a good insect net or shade net material to prevent insects from damaging plants when the ventilation is opened.

The roof is flat. This structure requires more wooden materials on the roof to prevent water from lagging or damaging the polythene film during rainy seasons.
The roof should also slant slightly so that it can enhance efficient drainage.

Multi-span greenhouses

These are greenhouses that cover a large area with a continuous structure. This lowers the cost of construction materials, utilize land and enhance balanced aeration and sunlight reaching plants.

Constructing greenhouses as individual structures in a pattern or same place will take a lot of wall materials or shade nets. The cost of such materials is reducible by constructing continuous structures.

Multi-span Greenhouses Structure

Many pillars on the inner part of the structure to support the roofing materials.
Gutters are required in between the roofs or ridges of the structure to drain water during rains.
The wall parts or roofs are large ventilators, with insect netting on the sides.
Roof ventilation is suitable for multi-span green houses.
