A note of caution…
At 6’ rib spacing, these structures are not intended to, or capable of handling very much snow load. This tunnel can handle greater loads by simply reducing the rib spacing and/or increasing the length of the anchor pegs.

It is important to get the correct amount of inward lean on the anchor rods.
If they are too vertical, it will be a challenge to get the rib on and if they are leaning too much they will loose some of their holding power.
Proper tension on the rope is critical to the success this type of “greenhouse” since it is the rope which is holding the plastic in place.
The plastic is secured lengthwise between 2 stakes which should be 10′ away from the last rib.
By pulling and securing the cover lengthwise first, you will minimize the cover dipping between the ribs.
