Large Greenhouses

We have a variety of widths and lengths of greenhouse structures from which to choose.

If you’re just trying to get a head start on the garden vegetable season (and maybe extending the growing season by a couple of weeks) consider our free-standing structures which use just one layer of poly.

If your intent is to grow all year round and heat the greenhouse then you should be looking at our greenhouse packages that offer a double poly roof, inflator fan kit and roll-up sidewalls for better heat efficiency.

COLDFRAME vs. GREENHOUSE

COLD FRAME usually has a single plastic covered structure and used as a season extender
GREENHOUSE usually has a double plastic cover with air in between and sides that roll up for year round use for better heat efficiency.

AVAILABLE OPTIONS

  • Custom widths, heights & hoop spacing
  • Roof vents & forced ventilation packages
  • Various types & sizes of doors with end framing priced separately
  • 8mm polycarbonate sheeting for roof and/or ends
  • Roll up sides for natural ventilation & reduced condensation
  • Cross ties for added rigidity, hanging baskets or crop support

Important Winter Care Articles

We have published a few articles regarding winter care and maintenance, and suggest anyone who has purchased a structure from us to review them to make sure your shelter is safe over this winter. As always, we are available for anything you are wondering or concerned about. We would be happy to help.

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.

It is important to note that the ice in itself is not an issue, even a very thick layer actually has enough strength to become self supporting. There are two potential problems though:

  • If the ice stays on the building, it usually has a rough enough texture that subsequent snow will not likely slide off. This scenario lead to major problems in previous winters when we had freezing rain, followed by a dump of snow and then we had rain. This can triple the weight on a building in very short order.
  • The other potential problem happens when you are attempting to remove the ice from the building. If the ice layer is not too significant you can gently bump the cover from the inside. ALWAYS start bumping the cover from the top. This way ice will slide over ice. Starting from the bottom creates a potential where the ice sliding down will fall back against the building and slash the cover. NEVER do all of one side and then the other. Work both sides simultaneously.

If there is the slightest doubt in your mind about the amount of weight on the building, bump the cover from the outside using something with a long handle.

If in doubt please don’t hesitate to ask.

Inflator Fan Overview

An inflator fan is a very small fan which is attached to the inner layer of a double layer structure cover. Because the inflator is a squirrel cage type of fan, it can run continuously against the back pressure it has created without over heating.

The primary benefit of the process of putting air between the two layers of cover is to reduce heat loss. By having this cushion of “insulation”, the building experiences a significant reduction in condensation. The air filled pockets acts as a shock absorber therefore substantially stiffens the building in very windy locations. Covers tend to last longer since they are always tight.

The closer you are to achieving dead air space, the more these benefits can be maximized. 4”-5” of air space is optimum. Too much air space will result in air movement and reduced efficiency. When installing a double cover, both layers are on the outside of the structure but only the inside layer is pulled tight.

For all of those who are either off the grid or too far from a practical source of electricity, stay tuned for our solar powered inflator fan announcement coming very shortly

Installing Multiple Covers into One Wirelock Channel

This post covers another one of our most frequently asked questions,

HOW TO INSTALL MULTIPLE COVERS INTO ONE WIRELOCK CHANNEL!

We hope the description and video can help clarify this issue a bit more. Thanks for your feedback!

The beauty of wirelock is its ability to hold multiple layers of covers, even covers in different directions (i.e. roof and ends or 2 long lengths).

Before starting you must at least have the cover tacked at the opposite end. This will give you resistance for pulling the cover tight.

Our wirelock channel will hold up to 3 layers of 6 mil plastic securely.

Two layers of 12 mil tarp will not be held securely in the wirelock channel. This is why we recommend that the top of the end wall tarp be sandwiched between the channel and the hoop.

If you have never installed these covers before, it is recommended to use at least 3 people.

  • After the bottom of the end cover has been secured, pull the end cover over the hoop first.
  • Person “A” will hold it from the inside of the structure in such a way that there are no wrinkles.
  • The roof cover can now go over the channel as well.
  • Person “B” will pull on the roof cover while person “C” installs the stainless spring steel wire inserts.
  • “C” will start from the peak and work down.

It is critical to remember that “A” and “B”, who are pulling on the two respective covers, must always be pulling at least a foot ahead of “C” who is installing the wire insert. This will allow a little give in the covers so that there will not be damage.

With more experience “B” and “C” can be done by one person.

It is also important to remember the wrist technique for installing the wire insert. Do not slide the wire straight back and forth. This causes abrasions on the cover.

As you move back and forth, apply pressure with the thumb on the next parallel spot of the wire insert.
Use a needle nose pliers to get the last tip into the channel.
The next wire insert does not have to be overlapped.

Featured Add-On: Center Pivoting Gable Vent

We wanted to remind everyone of the center pivoting gable vent that we offer as a simple solution to the challenges of venting a building.

For venting to be effective, it has to be as high as possible. This is a cost effective alternative to costly roof vents.

Part of the window swings in and part of it goes out. Because of this

  • rain is never an issue
  • the window is easy to control even in extreme winds.
  • Incoming air is always deflected up to mix with the warmest air.
  • The tubular steel construction makes it both lightweight and resist twisting over time.

A continuous rope goes from the top of the window to a pulley at the ridge, down to ground level and back up to another pulley and then to the bottom of the window. By tying the rope off to an eye bolt on a gable post, this allows for very simple control from ground level.

Please don’t hesitate to call us for more details or with any questions you have about this option for your building!

Video: Installing Anchors into a Base Beam

The main function of anchors is to prevent uplift. Do not forget about the “foundation function” as well which is meant to prevent settling or lateral shifting.

Improperly anchoring a building from up lift, down force and lateral movement will all, equally, cause problems and expense.

There are many different ways of anchoring a building because there are so many circumstances which people are dealing with.

When anchors can be installed at opposing angles, they work against each other and therefore will multiply their  holding power.

  • Care must be taken to stay away from anchors that will bend (i.e. re-bar).
  • When the anchors are going straight into the ground, care must be taken to ensure proper holding power. This is most often done with plugs of concrete.
  • When anchors have been extended out of the ground, care must be exercised to eliminate the possibility of outward lean.
  • It is important to consider the total amount of square inches of contact area between anchors and soil. Many time fewer big anchors is less holding power.

One thing which simply can not be stressed enough is that there simply is no such thing as too many anchors. Anchors are generally very inexpensive, especially when you are looking with hind site at some damage.
