The main technical parameters of this type of greenhouse are as follows:
(1) Greenhouse height: 8m;
(2) Internal clearance height: 4m;
(3) Outer clearance: 6m;
(4) Length: 12mx6mx5m (width x depth);
(5) Eave height: 2m~2.5m (from the top edge to the top);
(6) Top height: about 3 meters (internal clearance).
