Empowering Your Grow: One Blog Post at a Time

Why are greenhouse temperature and humidity uneven when the main sensor looks normal? A central reading may not represent conditions throughout the crop. Investigating greenhouse air distribution starts with comparing several locations at the same time, recording equipment operation and identifying whether the uneven conditions follow a particular row, obstruction, growth stage or control event...

What information do you need before planning a commercial greenhouse HVAC system? Start with your crop requirements, greenhouse layout, local weather conditions, moisture loads, available utilities and operating schedule. A useful design brief connects those details to the conditions the equipment must maintain, giving your project team a clearer basis for recommending heating, ventilation, hum...

Moisture is an unavoidable part of commercial greenhouse production. Plants release water vapour through transpiration, irrigation adds moisture to the growing environment and warm air can hold a significant amount of water.The problem begins when that moisture changes from water vapour into liquid condensation.Droplets may appear on glazing, pipes, structural supports, curtains and equipment. ...

An older greenhouse HVAC system can continue operating long after it stops delivering the efficiency, consistency or control a commercial grower needs. Fans still turn, boilers still produce heat and vents still open, but the growing environment may become increasingly difficult and expensive to manage.One zone may remain warmer than another. Humidity may rise overnight despite continuous equip...

Creating the right temperature and humidity inside a commercial greenhouse is only part of effective climate control. Those conditions must also be distributed consistently throughout the facility and, most importantly, through the crop canopy.A temperature sensor may indicate that a greenhouse has reached its target setpoint, but that reading does not guarantee every plant is experiencing the ...
