FAQ

Does it ship freight?
No. It ships free in standard boxes to your door.

How long does it take to build?
Most builds take one to two days with two people on a prepared site. One person can build it with extra time. Optional upgrades like doors and roll-up sides may add time.

Can a beginner do this?
Yes. The instructions and video guide break each step down clearly. Our USA based support team is available seven days a week if you need help during assembly.

What ground prep is needed?
Choose a level area with good drainage. Clear debris, remove rocks or roots, and make sure the ground is firm. Gravel or compacted soil work well.

Is this strong enough for year-round use?
Yes. With proper anchoring and seasonal care, the greenhouse is suited for ongoing use. In areas with heavy snow or strong winds, additional anchoring or periodic snow removal may be needed.
