Key Environmental Control Elements in a Commercial Greenhouse

A commercial greenhouse allows you to plant all year round regardless of the weather condition. This is made possible by mimicking the environmental conditions necessary for plant growth. The elements that control your greenhouse’s conditions are typically inbuilt during its construction.

Heat, cooling, and water are the primary elements commercial greenhouse manufacturers focus on. There are various solutions for control of these elements. Here’s a guide to understanding the best options for control of the various environmental elements in your greenhouse.

Heat

For heating of your greenhouse, the ideal choice is a hot water boiler. Bottom heat for your floors and under your growing benches can be provided using EPDM tubing placed in concrete or sand and under benches. If you need to shut down your greenhouse during winter to drain out water, a unit heater or hot air furnace is the best option.

Cooling

For natural ventilation, you can locate your greenhouse in an ideal place to benefit from wind gradient and breeze. For more positive ventilation, however, fan and louver systems are the perfect option. This system should have a ventilation rate of 8 cm/sq ft in the summer and 2 cm/sq ft during winter.

Water

A uniform irrigation system is vital to ensure all your plants get water. Drip irrigation for hanging baskets and in-ground growing beds, overhead irrigation for mature plants and mist for propagation areas are the common irrigation options. For farmers who want to automate irrigation, a computerized boom system that you can program to water various sections at different rates is their ideal choice.

With these conditions efficiently taken care of, you can be assured of a successful planting season. Your greenhouse manufacturer can advise you on the ideal condition for your crops. Even as you pick your best options, plan the systems for future expansion as your venture grows.
