Good light levels are essential for healthy plant growth especially from autumn until spring. Position your greenhouse or polytunnel in order to get maximum sunshine throughout the year.
* Aspect. Ideally align your greenhouse or polytunnel in a north-south direction so you won’t get any shading from tall crops that grow in the centre bed. Your polytunnel or greenhouse shouldn’t be sited next to buildings and trees as they would shade it and the roots of trees may grow into them.
All these greenhouses can be installed on foundations or dug into the soil by using the t type anchors included.
Originally greenhouses come with anchors, they are dug in the ground and after we concrete them in.
