February Features! *Winter and Your Structures*

We have a number of resources on our website to help you with taking care of our structure over winter. We have compiled a list of “Greatest Hits” below, that you can review at your leisure and please don’t hesitate to contact us with any questions if you are unsure or can’t find what you’re looking for. We are always happy to help.

The best place to start is the Winter Care Pages in our instruction manual.

We also have: Winter FAQs

Video: Norm explains the situations where you would need to remove snow from a Greenhouse or Storage Building and how to do it safely

Winter Care & Maintenance
Important notes for various situations
Our structures are designed in a gothic shape with a slippery cover to be lightweight and snow resistant. This encourages the snow to slide off quickly. This is not an industrial high snow load building….

Weather Cautions
These buildings are not industrial grade shelters and, as such, some caution must be exercised under some winter storm conditions….

Winter Storm & Your Structures
Many areas have been hit with freezing rain today and even though it has generally not been enough to warrant concern for the structures, it is a good time to recap some common things when dealing with ice on buildings….

Retightening a Loose Structure Cover
Re-tightening a cover does not have to be done in one day. Taking a short cut will leave you with more wrinkles. Areas with wrinkles will flutter more and cause stress points.
This will also cause the cover to deteriorate quicker……

Temporary Fix for a Loose Cover
There are a number of instances where a cover will need to be installed in less than ideal conditions. This can be either be on a windy day or in the cold (-10C or worse) and the job simply can not wait.

Season Extension: Hanley Caterpillar Tunnels
The real lure of these buildings is their low cost and simplicity to move. Generally the area is prepared in advance and then the tunnel is moved over the area when the planting is to be done…..

Happy Valentine’s Day and Family Day! We hope you and your family are staying warm, and getting excited for the upcoming spring and growing season! We look forward to working with you on your projects in 2021!

Modified Hanley Tunnel

One of our most popular structures is the hanley tunnel because it is the cheapest way of covering an area for season extension.

As a way of addressing some of the challenges and limiting factors with the tunnels, we have come up with a modified hanley.

The two areas where it significantly improves on the regular tunnel are the side clearance and the peak for snow shedding. Instead of using 24’ of steel to make 17’ wide and 7’6” high, we are using 26’ of material to make 16’ wide and 9’ high. It still uses 28’ wide plastic with extra at the ends to make the same kind of “tails”.

Sliding the plastic up on the sides is still the way that the tunnel is ventilated and you will still have the same challenges as far as creating access.

The re-bar anchors, base plates, clasps and rope are the same on the modified hanley as they are for the regular tunnel. We supply 5’ more of extra plastic for the tails since the building is taller.

The peak on the end hoops are very hard on the plastic, so we have designed a more rounded hoop at each end. It is strongly recommended to have 3 guides ropes at each end to brace back to the anchoring posts of the plastic.

Any structure with ends is not considered a Hanley Tunnel. We are more than willing to discuss the differences and benefits/drawbacks between tunnels and cold frames should you wish to know more.

The main thing which is critical to understand before going with a modified hanley is the extra wind load which the structure will be subjected to. Going from 7’6” to 9’ high, results in a 40% increase in the wind load. This issue is what makes the correct tightness of the ropes an even more critical consideration.

It is also the reason why we strongly urge customers who
do not have any tunnel experience to start with a regular tunnel.

Season Extension: Hanley Caterpillar Tunnels

The first area to discuss regarding season extension are those structures that are simple enough to disassemble and relocate to another spot-primarily referring to Hanley Caterpillar Tunnels.

The real lure of these buildings is their low cost and simplicity to move. Generally the area is prepared in advance and then the tunnel is moved over the area when the planting is to be done.

Since the original design specified 6′ hoop spacing, the intent was always to remove the cover before risk of heavier snow fall. More often now, growers are going to 5′ spacing (and sometimes 4′) to allow the covers to remain on longer or even permanently.

By having a smaller hoop spacing, it allows the cover to stay on permanently, which allows for a much earlier start in the spring.

The key to the concept of the hanley working is in the rope.

  • The back and forth pattern of the rope resembles the way a person would lace up a boot.
  • Typically there is a spring loaded clip at the base where the rope passes through.
  • Once the rope is fully installed, it is important to tighten it through three passes from end to end.
  • If the rope is not tight enough, the wind will create wiggle and movement sideways.
  • When the plastic is tight enough, it also allows the grower to slide the plastic up the hoop to allow ventilation.

Generally the plastic is about 25′ longer then the tunnel.
This allows the installer to bunch up (pig tail style) the extra poly at both ends between a pair of posts.
It is important to get the plastic as tight as possible lengthwise first.
There must also be a rope from the top of the last hoop to the tie off post.

There are a couple of challenges to consider with the hanley tunnels.

  1. One of these challenges is to create a proper entrance. Typically entrance is achieved by slightly lifting the plastic and ducking underneath.
  2. The other are of challenge is the low shoulder height of the structure. This restricts the use to a couple rows of taller items in the middle and a couple rows of shorter plants along the side. The width of the tunnel does lend itself to three regular size beds.

Once you have learned about the nuances of the hanley tunnels, and asked any questions that come up, you will be better prepared to have these efficient season extenders work for you and your application.

Feel free to look at our Hanley Application page for more information and photos, and give us a call with anything else you require.

We are pleased to have many happy customers these structures are working for, and look forward to you being next!

Organic Greenhouses/Shelters-uses and benefits

As we recognize and celebrate Organic Week 2020, we want to share a popular article from our website. We thank the organic farmers that go the extra mile for land stewardship and are proud to partner with so many of them. We will be sharing and highlighting some key organic related articles all week. We hope you find them helpful!

There are many benefits to having a greenhouse structure for organic growing and housing. They are often used a season extender for protecting crops from the elements, blight, and fungus. Since Organic growers and farmers do not use pesticides, this type of protection is often required for some of the more sensitive crops.smaller high profile

The structures are easy to move to allow the expansion of the growing area.These structures can easily help to give you the opportunity to grow more crops in a limited area. What many of our customers also do, particularly with Hanley Caterpillar structures, is start growing the early crops under the protection of the structure, and as the crop is stable enough, they move the structure to be able to start the next planting.

Knight Hanley Structure

Our structures are also used for organic livestock raising to ensure the animals have a healthy, safe and protected environment out of the elements. They are versatile structures, and only require the changing of clear to white plastic for the various uses. The environment allows the animals to have sunlight, but still get the shade they require.

The combination of the double layer of plastic, roll up sides, and inflator fan, on both the greenhouse and livestock shelters, helps to reduce condensation and keep the structure ventilated. We are excited to be working on a solar powered fan option for those off grid customers or if the structure is out in the field away from electricity as we know many of our organic growers and farmers are in these situations.
