Global Crop System

GCT has many years of experience as greenhouse manufacturers, product design, and implementation. This has allowed “Global Crop System" to continuously be developed and improved for all clients.


We have engineered our greenhouse growing system over the years to be the most optimal choice for progressive growers and clients. By putting steel where it counts, clients are given a long-lasting growing environment. The curve of the roof arch profile has made the “GCT” a virtually “drip-free” greenhouse.


Unsurpassed by versatility, reliability, and cost-effectiveness GCT will guarantee that clients with a long-range plan for the future will be set up for success with our controlled greenhouse system.
