Common installation questions:
Most customers complete the Sigma greenhouse installation in about 25 to 35 hours spread over a few days. The exact time depends on your experience and available help. If you’ve assembled kits or DIY projects before, it may go even faster.
If you’d prefer to have it professionally installed, Planta also works with a network of recommended greenhouse installers across North America.
We recommend having at least two people for assembly. While some steps can be done solo, lifting and securing the arched panels is much easier and safer with a second pair of hands - especially on windy days.
If you’d rather leave it to the professionals, Planta can recommend certified installers who are experienced with our greenhouse models.
