Technologies

Adapt to our client’s greenhouse projects

We offer a variety of different technology in order to adapt to our client’s needs.

Low-tech

Low-tech greenhouses offer basic manual equipment such as natural crank ventilation.

Models adapted to low-tech

  • Ground-to-ground—OvaltechTM
  • Tunnels greenhouses “Cold Frame”

This level of technology is ideal for :

  • lower volume production
  • limited budgets
  • operations which benefit from a very affordable labour cost

Mid-tech

Mid-tech greenhouses provide the opportunity to add equipment and to be automated.

Models adapted to mid-tech

  • Ground-to-ground — OvaltechTM
  • Gutter-to-gutter—LuminosaTM
  • TunnelProTM tunnels greenhouses

This level of technology is ideal for:

  • average volume production
  • clients who want to upgrade from low tech greenhouses
  • Clients who want to save on labour costs

High-tech

High-tech greenhouses offer fully automated equipment with a computer-controlled system that allows clients to accurately control the climate inside your greenhouse.

This level of technology is ideal for:

  • high-volume production
  • clients who want to save on labour costs
  • clients who have a larger budget
  • clients willing to invest in superior technology

Field results with Harnois high-tech greenhouses

  • Many producers have achieved quality export ratios above 95%
  • The majority of our clients tripled their output (in kilos per square metre), and lowered their labour costs.

Equipments

Our equipment makes it possible to adapt greenhouses to the types of crops being produced.

Differences between low- and high-tech

Low-tech

  • Basic protection for crops
  • Doesn’t allow for complete climate control
  • Requires more chemical products for phytosanitary control
  • Non-airtight structure that cannot be used for organic control of harmful pests
  • Quality and production are highly variable and difficult to predict
  • Very difficult, if not impossible, to produce year-round for most climates
  • Energy efficient

High-tech

  • Maximum crop protection
  • Ensures fully automated climate control
  • Requires fewer chemical products for phytosanitary control
  • Airtight structure that allows for organic control of harmful pests
  • Quality and production yields are stable and predictable
  • Potential for year-round production, no matter the climate
  • Requires more energy

Agronomic support service

Harnois is the only manufacturer to offer an agronomic support service. Our experts are available to assist clients to quickly master advanced equipment and avoid the errors associated with transitioning to high-tech.
