The importance of good ventilation
An indoor garden’s ventilation system is just as important as its lighting system or nutrient regimen. The ventilation system is responsible for maintaining the atmospheric conditions (temperature, humidity, and CO2 levels) within an indoor growing space. Temperature, humidity, and CO2 levels all directly affect photosynthesis and, therefore, the way a plant grows and develops. When these variables are kept in the desired range, a plant’s ability to photosynthesize will not be compromised. Like other key contributors to a successful indoor garden, consistency of the ventilation system is important to providing the optimal conditions for accelerated plant growth.
In a hobby indoor garden, the ventilation system may consist of little more than intake fans, exhaust fans, and recirculating fans. For more advanced garden set-ups, the ventilation system could also include air conditioners, dehumidifiers, and CO2enrichment equipment. Regardless of whether a gardener implements a basic or more advanced ventilation system, the basic functions of the ventilation system remain the same: to provide uniform temperature and humidity levels within the desired range and to supply the plants with CO2 for photosynthesis.
The optimal temperature range for most indoor gardens is 72-80˚F. In grow rooms with enriched CO2 levels, the optimal temperature range is a little higher (80-85˚F) in grow rooms with enriched CO2 levels. The pieces of equipment used in the ventilation system will help a grower maintain temperatures in these ranges. The most common piece of equipment in any ventilation system is a motorized fan. For a small indoor garden with a low heat signature, a single fan could make up the garden’s entire ventilation system. An exhaust fan could remove the excess heat from the growing area while drawing fresh air into the garden space. The fresh, cooler air would help lower the temperature of the growing space and contain CO2 for the plants to “breathe.” Larger growing spaces or gardens with more grow lights would need multiple fans to regulate the temperature, humidity, and CO2levels. Using motorized fans for both the intake and the exhaust is common in medium-sized grow rooms. In this type of set-up, the fans work together to evacuate air within the grow space and replenish it with fresh air. Atmospheric controllers with built-in thermostats and humidistats allow growers to automate motorized fans within the growroom and to provide more consistent atmospheric conditions. Recirculating fans are another valuable tool for creating uniform atmospheric conditions within the growing space as they help to “mix” the temperature and humidity of the garden’s environment.
Other RAM Products
The Ram Bug Barrier Insect Screen is a cover that fits directly onto your air intake system. The shield is made up of a layer of fine mesh – the holes are small enough to ensure bugs are not being sucked into your grow-space without having a negative effect on air flow rates. The Bug Barrier also comes with Velcro fasteners sewn into the edges. Each segment of Velcro has a separate matching piece that comes with a peel-off sticky side. These pieces of velcro can be stuck around the edges of your ducting or spigot and used to secure the shield in place.
