Large Greenhouses

We have a variety of widths and lengths of greenhouse structures from which to choose.

If you’re just trying to get a head start on the garden vegetable season (and maybe extending the growing season by a couple of weeks) consider our free-standing structures which use just one layer of poly.

If your intent is to grow all year round and heat the greenhouse then you should be looking at our greenhouse packages that offer a double poly roof, inflator fan kit and roll-up sidewalls for better heat efficiency.

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 for 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
  • Cross ties for added rigidity, hanging baskets or crop support

The benefits of going to a bigger structure

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.

A smaller air volume has less natural circulation.
Proper air circulation for plants is critical regardless of the season.
Think of a deep pond versus a shallow pond. The deep pond never has algae on the surface because of the increased movement.

Going with a taller greenhouse will automatically increase the circulation the same way.

Another point to consider with a taller greenhouse, is that there is more open space above the plants.

This open space is where moisture can go, away from the plants even before the greenhouse ventilation system does its job.

With a lower greenhouse, moisture is always in close proximity to the plants. In a taller structure, the plants will be dry much sooner.

Moist plants in a stagnant air mass are prone to disease. These plants will, as a result, produce less.

As always, be aware of the bigger picture.
