For information on which model might work best for you, scroll down below to explore the key benefits of each.
Harsh climates require less space, 4 ft, between each truss to ensure structural integrity year-round. Moderate climates, the most common, require 5 ft spacing. And mild climates can be spaced at 6 ft apart.
The spacing from one truss to the next is an increment of the greenhouses length. Thus, length must be divisible by the truss spacing.
The sidewall height will depend on acessibility needs as well as what crops you are growing.
