Covering Ends – Plastic & Tarp

Please refer to the Ends page in the assembly guide as well

When you are covering the ends of the structure, there are some similarities and some fundamental differences when you are covering with plastic or with tarp.

The aluminum wirelock channel must be installed on the top side of the hoop before you start the cover. The framing must also be in place before you are putting on the cover.

Your cover will be a rectangle and you must double check if the two ends were supplied as one piece or not.

  • You start at the base of one side and go continuously over the peak so that there is not an edge at the peak.
  • The cover gets fastened, temporarily, at the base first on either side of the door and then pull out to the corners.

If there is ANY wind, do into the wind side first.

  • Please remember that whenever you have wrinkles or folds, you will pull 90 degrees to the wrinkle.

Excess on the end covers will only get trimmed off after the roof cover is on as well.

If you are covering the end with plastic

  • you would go with the extra of your rectangle and fasten it temporarily to the back side of your framing.
  • At the very most, at this stage you will put part of a wire insert on either side of the peak.
  • When the cover is sitting smooth, you can put some strapping on the vertical framing to hole the cover in place.

If you are covering the ends with tarp

  • you will need to remove the wirelock channel first.

This may seem like double work, but the channel is now curved to the building with the required screw holes.

  • The end tarp cover is sandwiched between the hoop and the bottom of the wirelock channel.
  • When you pull the tarp over the peak, you will reinstall the wirelock channel from the top and work down.
  • If you do the left, right or bottom first will be determined by where the wrinkles are (if any).

Please don’t hesitate to call if you have any questions at all and please watch the videos on our YouTube channel for more information

Choosing a Cover – Poly vs Tarp

Everyone wants to save money but they also want value for the dollars invested. One of the things that sets MSS apart is with the cover choices we offer.

The two main areas of covers we offer are the 12mil woven tarps and the 6mil plastic. (Other options available, call to confirm)

Both of these choices are by no means the heaviest that are out there, but they do provide excellent life span for the investment.

When you consider the cost per year on our 12mil white tarps, which have an 8-10 year expected lifespan, they stack up very favourably to the 20-24mil covers that are available.

  • The main reason 12mil is even an option for us to use is that our hoops or ribs are much closer together and therefore provide much more support to the cover.

Using 6mil plastic gives even more options.

  • Going clear (greenhouse) allows the necessary light transmission for plant growth.
  • Going white (livestock) allows light while still providing a shade factor.
  • The option of a double layer with air between, provides even more benefits for heat loss and condensation reduction and added stiffness in extremely windy locations.
  • The biggest attraction for the 6mil plastic is the life span you get for the investment.

Solar Powered Inflator Fan Update & Alternative

We have been continuing to get many inquiries about solar powering the inflator fan for greenhouses and livestock buildings, which is used to put air between two layers of plastic roof cover. For the last year we have been experimenting with a solar collecting package to determine what is required, while we work to keep our interested customers updated along the way.

The first thing that must be emphasized, is that you MUST use a squirrel cage type of fan and not a propeller type. The propeller type can not continuously run against back pressure.

The output required will be determined by the size of the greenhouse or livestock building. Our regular 110 volt fan draws .25 amp and puts out 80 cfm. Some small buildings can use a smaller fan and some of the bigger ones require our double output fan which gives 130 cfm.

Our inflator fan works quite well going through an invertor. Any 12 or 24 volt fans which we have tried have been extremely noisy and therefore not feasible.

The biggest challenge which we encountered, is that the specific time the fan is needed the most for heat insulation, is also the time where there is the least capacity for generating power.

We used a single solar collector and a single battery and there was simply not a quick enough capacity for the battery to hold charge when we had several consecutive cloudy days in December/January

To add another solar collector to an already fairly expensive package, really becomes prohibitive and can deter from moving forward with it.

Based on this experience, we wanted to offer an alternative that balanced economy with feasibility. We have come up with a way where the extra roof plastic can be used on the inside of the structure.

This means that you would not need the inflator fan but still have the effect of double plastic with the air pocket for better heat efficiency. This system does require a bit of extra “fiddling” but the net cost will be a little less.

1. The structure is covered with a single layer of plastic just the same as you would if you were only doing a single layer.
2. Take the second piece of plastic inside the greenhouse and fold it double lengthwise.
3. This double plastic will be attached to the underside of the ridge using the same aluminum as you would use to fasten the plastic to the roll up pipe.
4. Next remove the purlins from the one side of the structure and after you have pushed over the plastic, reinstall the purlins under the plastic. You will be pushing the bolts through the plastic.
5. The plastic will be fastened with wirelock to the underside of the end hoops.

We have already had some customers try this out and are very happy with the result. Please call us with any questions or to discuss your specific application and situation where you might use this. We would be happy to help you with your project!

Greenhouses 101 & 202

Norm spoke at the Guelph Organic Conference January 31, 2015 on Greenhouses 101: Knowing the basics before you buy-Choices and Consquences
You can find the articles and information posted, as well as a video of his presentation and the Q&A below.

Greenhouses 101: Orientation and Location
Greenhouses 101: Knowing the basics before you buy
Greenhouses 101: Greenhouse Choices

Norm did a presentation at the Guelph Organic Conference on Greenhouses 202: Making sure your structure survives the elements. The presentation is broken into three parts for easy viewing, the last section of which is the Q&A. These tips apply for greenhouses, storage buildings, livestock shelters, really anything we sell. Key Points Covered in the presentation:

1. Some basic principles of engineering so that the forces exerted on the buildings could be better understood.
2. The many components of anchoring. Anchoring prevents a structure from settling under snow load, prevents lifting under aerodynamic forces and prevents shifting with wind forces.
3. The similarities of an airplane wing to the shape of a structure. What happens when surfaces become bigger, wider. lower and higher.
4. How uneven loads can happen and how to prevent them.
5. The proper procedure to removing excessive snow load

Backyard Greenhouses

Threndyle1

 click here to download our backyard greenhouse brochure(please see pricing below)

This 12’W x 18’L High Profile Mini Greenhouse has a single layer of 6 mil plastic for the roof and ends.  It is used as a “season extender”.  To make it a year round structure a second layer of 6 mil plastic would be added to the roof, and an inflator fan kit would be supplied to blow air in between the layers.

This building sits on a 4” x 4” pressure treated beam (there are other environmentally friendly alternatives available as well), which is anchored into the ground.  Ventilation can be done manually  (through doors and windows or by adding roll-up sidewalls), or mechanically by adding an exhaust fan.

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 and 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

Movable Structures

Please download our Movable Greenhouse Information or our movable brochure for printable versions of this information.
Or visit the movable application page for more details

Welded base is $11.00 per lineal ft of structure. That means if your structure is 36′ long, you would calculate 36 x $11 = $396.
Skis only are $5.80 per lineal ft of structure
Our prices exclude installation, foundation, freight & taxes unless otherwise specified. Please inquire with any concerns.

Please ensure you read the instructions and considerations  FULLY and understand all the points before considering purchasing a movable greenhouse.

The intent of this page is to point out concepts rather then discuss specifics. There are simply too many possibilities to cover them all. It is our purpose here to make sure you realize the possible consequences of some of your ideas and to point out potential pitfalls.

The idea of a moving structure allows a user, with a little creativity, to protect 2 or 3 times as much area with the same building and investment. It is a very simple concept as long as some basic guidelines are adhered to. If these guidelines are not followed, the building can easily sustain significant damage. The stress of pulling must be distributed evenly to eliminate or greatly minimize the risk of damage.

If you are moving a structure often or over longer distances, please call to discuss wheel optionsmovable skis

Structure details

17’ wide with 92” centre height
1”x2”x24’ galvanized 1 piece ribs
Ribs typically spaced at 6’ apart
5/8” rebar (2 per rib) 48” long suggested
1/4” polyester rope
Base plates with clasps

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 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 a minimum of 12’ away from the last rib. By pulling and securing the cover lengthwise first, you will minimize the cover dipping between the ribs.

We now have a modified Hanley which is narrower and taller, with a two part hoop. Pricing is available upon request. Due to the substantially different wind dynamic, the modified Hanley is not suggested as your first Hanley experience.
