Hanley Caterpillar Greenhouses

We offer these structures with 17′ wide hoops at 6′ increments, standard. 4′ & 5′ spacing is also available, as well as our modified Hanley for more experienced growers
Ultimate in Low Cost, Portable Season Extending Greenhouses
A note of caution…
At 6’ hoop 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 hoop spacing and/or increasing the length of the anchor pegs.

Additional Notes
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 hoop on and if they are leaning too much they will lose some of their holding power.
Proper tension on the rope is critical to the success of this type of “greenhouse” since it is the rope that is holding the plastic in place.
The plastic is secured lengthwise between 2 stakes which should be 10’ away from the last hoop.
By pulling and securing the cover lengthwise first, you will minimize the cover dipping between the hoops.
