Attaching the Covering to the Dome:
Method 1: Using the Dual Covering Hubs:
The Dual Covering Hubs have an extra ridge at the edge of the hub that allows you to
attach the greenhouse plastic to the hub by cinching the zip ties over the plastic above
the ridge, which secures the plastic to the hub.
The design of the Dual Covering Hubs allows you to attach two layers of greenhouse
covering to the dome, one on the inside, and one on the outside. This creates a “dead
airspace” insulation pocket, and increases the greenhouse's ability to hold heat during
the nighttime hours.
To attach the greenhouse covering to a Dual Covering Hub:
Connect 3 Heavy Duty 8” Zip Ties together in a “daisy chain” circle, with each of the
Zip Tie Ratchet Knobs on the outside of the circle.
