Growing Over Winter in a Greenhouse

There are quite a few ways to make a greenhouse more heat efficient to make it feasible to grow either through the winter or for a large part of it.

The first thing to determine is what crop(s) you wish to grow since a number of plant varieties would be considered cold weather crops. The heat requirement would be considerably less.

Since the majority of heat loss is through the roof, the most common method of making a greenhouse more heat efficient is by adding a layer of plastic to the outside. With the benefit of a small blower there is an air pocket created. The closer that this air pocket is to “dead air” the less heat transfer that there would be. 10 to 15 cm is considered the ideal gap. When there is more then 15cm there will start to be movement of air and greater heat transfer. It is impossible to have a perfectly uniform space because of the way the plastic goes over the ridge and is fastened around the edges.

It is important not to have any holes in the plastic. The resulting air loss with a hole would result in air movement and less heat efficiency.

It is often thought that a lower greenhouse is easier to heat since there is less surface area to lose heat. The reality is that the bigger air volume of a taller greenhouse is less likely to have the temperature fluctuate.

To make a structure more heat efficient, the north wall could be insulated. Care has to be exercised in insulating ends since it is important not to create extra shading. Insulation can be put flat on the ground around the structure as a way of slowing down the cold radiating into the structure.

Another trick that some people have used effectively to reduce heat requirements is to make small tunnels over the beds of vegetables. This works well for the night time. It is important to have this cover removed in the day time to maximize the value of the sunlight.

If your intention is to only use part of a larger structure through the winter, it is wise to hand a curtain for the length of the ridge and then only use the south facing side. This maximizes the benefit of the sun and minimizes the effect of the cold wind.

With a little creativity it is easy to get benefits from the greenhouse even in the winter.

With the new restrictions and protocols which were mandated by the provincial government on Dec. 26, it will be necessary for us to verify if there are any of these restrictions which apply to any of the buildings which we supply. We will be posting this information as we become aware. As per last spring, we know we are able to sell and deliver agricultural buildings and will be finding out for any others.
Any orders which customers will be picking up, will be considered “curb side pick up” and as such, these orders must be prepaid and there will not have any contact with our staff.
Customers picking up orders will be required to wear masks while on the MSS property and are not permitted to look around.
Customers who are receiving an MSS delivered building will receive our delivery protocol a few days in advance. This protocol must be acknowledged and agreed to before a delivery can take place. Please contact our office if you would like to see a copy of this protocol or look on our website here
We thank you for your patience as we continue to work through this challenging time.
We will post further updates with more information as the information becomes available or changes.

Curbside Pickup Helper

With the new provincial guidelines many businesses have been forced to go with curb side pick up. Terry Cormack and his staff at the Palmerston Home Hardware have certainly made the process more pleasant for their customers during the messy weather of the winter months.

We were lucky enough to get our new entrance shelter up yesterday. What a great help for curbside service! With the weather we’ve been getting today, our customers have really appreciated a little shelter! A big shout out to our local manufacturer Multi Shelter Solutions – right here in Palmerston!! Norm Eygenraam and his team at Multi Shelter Solutions put an extra effort into getting the bits and pieces made just before Christmas. And an extra thank you to Norm for his expert guidance with assembly yesterday! I would highly recommend Norm and his team if you are needing a solution to your shelter challenges. Check their shelters out at www.multisheltersolutions.com, or give them a call at 519-343-2335.

This 10’ x 12’ Multi Shelter Solutions building allows customers to wait for their order out of the snow and wind. With this “relative comfort”, it is easier for customers to be patient while the store employees do their best in these challenging times.

With the portability of this unit, when restrictions are lifted, Terry will be able to move the shelter to the back of his property where it can shelter his forklift and other miscellaneous equipment.
