Greenhouses straight walls

Greenhouses with straight walls offer important advantages:
+ Higher walls: so more light, which results in better cultivation.
+ A straight-walled greenhouse also offers the possibility (everywhere in the greenhouse, cf. side walls) to cultivate in height = extra cultivation volume. This way you can use every centimetre of your greenhouse.

For example: You can place your tomato plants across the entire side of the greenhouse. This way you can organize your greenhouse optimally!
