>>2779940I screwed the feet to some pressure treated wood and covered the wood base in dirt on one side because the green house straddles the edge of the garden. Its also much heavier than a typical greenhouse of that size since I made it out of an old gazebo frame with 4x the footprint. It has been very stable even on days where we had 90 km/h winds, but it never really takes the full brunt of the wind as it is shielded by fences.
