How Can I make my greenhouse its best?

Different tips to make it more efficient, proper space for plants, proper light,
when to heat and not

There are numerous ways of making your greenhouse more efficient and a better return for your investment.

The first question which needs to be answered, however is, “What does it need to be efficient for?” The answer to that should be in line with your goals and priorities for your greenhouse.

As an example, if you are not going to be growing in the winter, you will not need to make the structure “heat efficient” but you will need to ensure that it is “snow efficient”. If you are growing in the greenhouse through the summer time, the efficiency of your ventilation system is critical.

Making your structure more heat efficient (summer perspective) will be expanded on in post #5 and more heat efficient (winter perspective) will be expand on in post #6.

When you intend to start plants in early spring and then move the greenhouse to start another crop, the moving process can be made more efficient by installing “skis” under the base.

Anchoring concerns are touched on in post #3. This is also a way of making more efficient use of your property with investing in more greenhouse space.

When you implement a trellising program, you will make more efficient use of the floor space in your greenhouse. It is important to consider the need for your plant load being balanced on your structure.

Another important thing to be mindful of is the shading that is created when you implement vertical growing. Under certain conditions you may need to consider supplemental lighting to make things grow.

One consideration that is important to be mindful of as well, is that in the confined space of a greenhouse, you can not grow everything. This is not just a space limitation, but a climate limitation.

Certain plants prefer it warm and some like it cool. Other plants prefer wet and others dry. It will be more efficient use of your greenhouse if you collaborate with a like minded person. You grow more of certain things and the friend does likewise and then you trade the extras.

Here is to working together and growing together!

How do I make sure it stays where it is supposed to?

Pointers on anchoring, what kind of things will impact holding power of anchors,
anchoring after moving a structure

A phrase Norm has used thousands of times in his career is, “There is no such thing as too many anchors.” We consider it important to help customers understand the aerodynamics involved with a greenhouse shape.

The relatively small cost of the anchors is a short-lived savings after a building has blown away or shifted. By understanding and implementing what is required you can ensure a long term usage of your structure.

The job of your anchoring system is to counter the three aerodynamic forces working on your building.

Down force is usually seen as snow load
Up lift and lateral shift are forces typically associated with wind load
Wind going over a structure creates lift similar to wind going over an airplane wing

The first thing you will need to assess is what you are actually working with. If you have bedrock close to the surface, you have large rocks, or you have straight sand, it will impact your options for anchoring.

The actual holding power of your soil is an important consideration. Soil that has been recently excavated has considerably less holding power than soil that has not been moved in a long time.

The total surface area of an anchor post in contact with the soil is an important consideration. Large and short may have more contact area than long and slender.

When anchors can be used in alternating directions, it will multiply their individual holding power.

Wet soil usually does not have the same holding capacity as well drained soil. An important consideration here is rainwater which is shed by the building. As an example, with a 16’ wide structure, 8’ of rainwater goes each way. This means that the narrow area next to your building get 8 times the rain that the rest of the property gets. If you have poorly draining soil, this could be a potential problem.

If you are planning to use the movable structure option, proper anchoring has some additional challenges. Since your building is vulnerable to sudden increases in wind during this process, your anchoring protocol needs to be done quickly. Always do a test in the new area to confirm what you will be working with. With the quickness that is required, there is also a reminder that taking shortcuts will come back to haunt you.

We would like to reiterate, “If you are not 110% sure, please ask” There is no situation out there that is so unusual that we have not already been through it.

Your long term success is very important to us!

We hope you are finding value in this series of posts, helping you prepare for your new growing adventure! Reminder that the deadline is May 31st for Fall Delivery. We look forward to working with you for your projects!

What is the best size and shape for what I want to do?

Covering the sizes we are offering and when it would be best to choose from the website for a more custom situation.

Determining the space that is required to meet your objectives will be your first consideration. This goes beyond the foot print or floor space which you would need for the plants you wish to grow.

In our Self Sufficiency packages, we are offering the convenience of 3 choices. There may be a situation where none of these choices will meet your short term objectives or long term goals. If that is the case, it would be advisable to explore our website for a more suitable package in the context of what you are learning here. The self sufficiency packages are meant as a simple starting point, but sometimes simple isn’t always the best choice

If it is your goal ultimately to have more than one greenhouse, consideration needs to be given for how the second or third building would fit on your property. As an example, if you have a total of 50’ wide available and you build 16’ now, it restricts your future options. Going a little longer now (if that fills the space) is much cheaper and simpler than doing an addition.

If it is not your intent to grow (and heat) through the winter time, it would be important to have a structure which would efficiently shed snow. Using a more snow efficient shape does not mean that the structure can be left totally unattended for extended periods of time. If that is going to be your situation, we have options for building structures to meet that requirement with closer arch spacing.

A very important reason for needing a taller building would be the need to use the vertical growing option. You will be able to grow more rows on that foot print because of the side clearance provided. If you plan to only grow short crops in the soil a lower greenhouse will work.

A point that many overlook in their consideration of the importance of side height is that they intend to work the ground with a rototiller.

A final point for the shape consideration, has to do with wind load. Wind load increases exponentially as the building is taller. Especially if your property dictates orienting the building across an extreme prevailing wind, it would be advisable to go with a lower profile.

Here is to comprehensive planning!

Where is the best place to put a greenhouse?

Considerations for determining optimum location for growing, air flow, snow shedding and ground moisture

The first bit of advice we share when asked that question is “Do not put a greenhouse in a place that is not good for anything else”.

You need to pick the best spot to accomplish the goals for your greenhouse. Any of the reasons why this spot would be less than desirable, will come back to haunt you.

This is particularly true when it comes to ground water. If a particular piece of land is always moist or has a very high water table, moisture will be an ongoing problem. A greenhouse will trap and exaggerate excess moisture and become a very unhealthy spot for plants.

If the soil is sub-standard or undesirable where you put the greenhouse, you will be putting extra effort into bringing the soil up to standard.

Proper consideration needs to given to shading on the property. Plants grow in direct proportion to the amount of daily light they receive. Really analyze where and when shade happens. Vegetables and flowers need sun.

A greenhouse needs to be level from side to side so shed snow uniformly. With uneven snow load on a building, it will surprise you how little snow can be a problem.

Excavation to level a site is usually expensive and messes with the make up of the soil. There are ways to build up the low side if that becomes necessary for the location of your choice. Some end to end slope is not a problem structurally.

It is generally acknowledged that a north/south orientation will pick up the sunlight better but this is not a serious consideration unless you are into production crops.

If your prevailing winds are constantly hitting the side of the structure, there will be a sideways push which is good to avoid. This orientation will also encourage uneven snow loading. Ventilation is typically easier if the prevailing wind hits the end of the building.

Since the chances of having the “perfect” location, is not likely, it is important to evaluate all of the angles. Some of the undesirable points can be worked around better than others.

By doing a thorough assessment and then prioritizing, you will be able to come up with the closest to perfect that is practical. You will also have an idea beforehand on what needs to be done sooner than later.

Here is to happy planning and planting.

Structure Options

We don’t bend any steel before we get an order. This allows us to customize our products for your structure requirements. We use 7 different lengths of steel, and can interchange the way we bend them to give you the same shape, with less height, or slightly different width if that’s what you require. You can see more about the profile shapes and heights on our profile page

We have engineered drawings for our standard buildings to help you get a building permit. It is impossible to have them for all the variations we offer though, but we do have them for most of our standard buildings. Please let us know if this is something you will require. PLEASE REVIEW OUR 2023 UPDATED BUILDING PERMIT ARTICLE

We have provided sample prices on each of these pages to give you a starting point, but have any width available from 10-36′, and can go any length you require. We’ve done them up to 300′ long! Typically we do structures at 3′ and 4′ spacing between hoops, but can go 2′ spacing for extremely high snow areas and 6′ spacing if it will be left uncovered in the winter.

Our structures have a standard Gothic Profile that comes to a peak, to shed snow more efficiently. Our structures are Canadian built for Canadian seasons. We add wind braces to ensure stability in windy areas, and can give you other tips for winter maintenance and snow if you are especially concerned.

We also offer our High Profile structures, which give around 2′ more clearance than our regular standard Gothic profile. Up to 20′ wide our high profile uses 1″x2″ steel, and we offer a heavy high profile option that is 20′ wide and uses 1″x3″ steel. 24′ and wider uses 1″x3″ steel as standard.

We have also created our Cathedral Series, which is our standard gothic arch flipped around, to give more usable height, with less floor space (for RVs as an example). see here. It is more susceptible to wind, because of the straight sidewalls. No snow stays on this shape at all, unless there has first been a wet slushy rain/snow, and then a freeze. This style is available in widths of 18′, 16′, 14′ and 12′

We welcome your unique challenge and look forward to helping you find your shelter solution!
