These buildings are not industrial grade shelters and, as such, some caution must be exercised under some winter storm conditions….
Snow removal, when occasionally required, is a simple task. Uneven snow loading is deceiving, since the total weight is not a problem but the lateral force can cause the hoops to distort.It is rare to have any significant snow build up on the roofs; however,
A wet snowfall followed by dropping temperatures
A building 90° to another building that has a higher roof, could cause a surge in snow weight when the snow on the upper roof slides off.
Preventative measures for excessive snow build up (where possible):
Install a heat source to melt the snow
Economical additions to increase your structure’s snow resistance:
Use closer hoop spacing for the first 12’ section away from another bigger building
Pointers for removing snow:
Use a padded piece of 1×4 wood on a pole (create a “T” shape) as the best tool for gently bumping the inside of the cover
Freezing rain, followed by dropping temperatures, Lots of snow followed by rainfall. It is easy to triple the weight of the snow load in 30 minutes.
What are some of the benefits of going with a bigger structure over a smaller structure?
Budget often dictates that someone needs to start small, especially when a person is just starting out as a grower with a greenhouse.
There is also the perceived notion that staying smaller means less heating cost. In itself, that is true, since heat loss is in direct proportion to surface area exposed to the outside.
As I have mentioned before, it is very important to weigh expense
against return. …..READ MORE
