Winter Care of Your Structure

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.

Season Extension: Moving Your Structure

A significant part of season extension involves moving an intact structure.

This basically allows you to get two (or possibly three) plots of production from one investment.

The idea is to start a relatively cold tolerant crop very early in the season (the timing will be different in different locations).

  1. Once the crop is firmly established in location A, (and it has warmed up) you will move the structure to location B and start another crop.
  2. You will harvest the crop in location A and then after working the soil, plant another crop in location A which is intended for fall harvesting.
  3. After location B is harvested and before frost you will move the structure back to A.
  4. Instead of doing twice in location A you could also choose location C.

A structure can be equipped with wheels which will run over the soil. There is quite a bit of flexibility where you go and the terrain you navigate.

The structure can be equipped with rollers on a track. This will determine where you go and this is usually intended for moving a bigger structure with fewer people.

The most common method of moving is sliding the structure on the soil. The base rail can be wood or steel.

It is critically import to understand the logistics of moving on a structure before you start. It is not hard to move a structure but it is also not hard to do damage.

Having a plan for proper anchoring is very important for a moveable structure. Your structure is at a vulnerable state when you release the anchors. Once you start, the job must be completed quickly. You have to be aware that the anchors may not come out or go back in easily so you may need to give yourself some extra time.

One other area of consideration on a moveable structure is the ends. There must be some sort of a flap or vent along the bottom so that when a structure is being moved, the ends will not uproot plant material. Generally speaking to have this ability in the ends takes away from the structural integrity, so some extra anchoring may be required.

You can see more information and photos on our movable information page. Please don’t hesitate to call us with ANY questions you may have. This can be a very useful addition to your structure, but must be understood correctly.

Season Extension: Ventilating & Heating

To make your greenhouse more of a year round functioning entity, there are two main areas in which you have to make the structure more efficient-Heating and Ventilation.

1. Heating is your biggest expense for the winter so retaining heat is a priority.

The easiest way to retain heat in your greenhouse is to install a double poly cover with air in between. A small squirrel cage blower attached to the inside layer of plastic aids in maintaining air between layers.

The more dead air space between these layers you can create, the closer you will be to achieving a 30% reduction in heat loss. Holes will result in air movement and therefore less efficiency. 3″-5″ consistent space is ideal. It is a given that you would have less then that around the edges and over the ridge.

Double plastic will have a considerably longer life span. It is important to realize that as plastic gets older, the light transmission will be reduced which will reduce production.

Infrared plastic (IR poly) does further reduce heat loss and increase light diffusion so it can also be a consideration when looking for ways to reduce heating costs.

2. Ventilation is also one of your biggest considerations for the warmer times of the year. Ventilation can be done through forced or mechanical methods or passive through vents or roll up sides.

Vents are extremely effective since they can be placed higher up where the heat needs to be expelled. Mechanical ventilation is more costly both up front and to operate but it is easier to control since it is attached to a thermostat. For mechanical ventilation to be effective, it needs to be sized and located properly.

Roll up sides are less costly and simpler to install but are restricted by the fact that you have to be there to open and to close.

Climate control is especially challenging in the spring and the fall since most days you will have the need for both ventilating and heating.

One area that you need to be especially aware of is stagnant air. Without proper air movement, circulation and exchanging, stagnant air can cause many different types of diseases. It is important to understand what your plants require

Stay tuned for more on our series about Season Extension and Your Greenhouse including Norm’s talk at the Guelph Organic Conference, coming soon!

Guelph Organic Conference Update

Please note we will not be at #goc17 until the afternoon. We look forward to seeing you and chatting then

It was a wonderful day yesterday at the trade show and with Norm speaking. So many great questions.

We will have Norm’s talk posted next week on our website and YouTube channel so stay tuned!

Thank you to everyone for your interest and enthusiasm!

Guelph Organic Conference: Season Extension Technology 

Come hear Norm speak this morning at the Guelph Organic Conference 

“Season extension technology” is a broad topic which includes making your existing greenhouse into a more efficient year round production space. Season extension also includes the use of your structure in more then one place. Norm is looking forward to sharing from his 40+ years of knowledge and experience to help you get better value out of your greenhouse dollars. This workshop will build on what was presented previously in Greenhouses 101 and 102.

Multi Shelters Website Updates

Here at Multi Shelter Solutions, we do our best to provide flexibility in choices, quality of service and excellent value for the money. Due to some significant increases we have received on the galvanized tubular steel that our hoops are manufactured from, we have needed to raise our prices, effective immediately. The prices that you will see on the current application web pages are the correct and up to date ones.

We have also updated the sample prices for replacing the roof covers to the website as well so that you will be able to anticipate those costs down the road. These are only meant as examples, and as always you’re free to give us a call for your specific project.

Finally, it is with a sense of amazement and gratitude that we see how many people are using our website as their primary research tool for figuring out their next building purchase. There has been over 150,000 views now in approximately 28 months. Your feedback is appreciated!

Thank you for your patience and loyalty. We appreciate the opportunity to work with you on your next shelter project!

Winter Care & Maintenance

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

Please see our Winter Care & Maintenance Page and  the WINTER CARE & other key points page in our installation guide for additional information

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. We do our best to always point out applications where the capacity of the structure is being compromised. Extra hoops or thicker steel are an economical way to increase wind and snow load capacity. We take pride in the sturdy shelters we manufacture and supply, but must point out that we cannot warranty against weather conditions.

Snow removal, when occasionally required, is a simple task. DO NOT GO INSIDE A BUILDING WHERE THERE HAS BEEN OBVIOUS STRESS!

PLEASE READ MORE………

We Look Forward to Helping You Find Your Shelter Solution!

Here at Multi Shelters we can work with you to fit whatever budget you have in mind for your project and publish sample prices freely for you to compare. We have found a balance that provides the economy so many seek, while not sacrificing any quality of the structure or customer service. Feel free to contact us for a custom quote for what you have in mind. We can work together to reach your goals.

Our biggest niche still remains that we don’t bend any steel before getting an order. We are able to customize it to fit in just the right spot, or alter how it’s done for your unique request. We bring over 43 years of experience to each and every call or email that we receive from potential and existing customers and welcome standard as well as outside the box projects.

That factor is how we’ve come up with our “igloo” structure, the airplane hangars, our “flying” greenhouse that was lifted onto an apartment building, and more! We pride ourselves on being able to help you find your best shelter solution, no matter how “out there” an application may seem. We’ve seen pretty much everything and look forward to your project ideas and challenges.

Check out our application pages to get you started and start the ideas flowing, there’s many to choose from. Thank you for your interest in Multi Shelters and we look forward to hearing from you in 2016!
