The Importance of Humidity in Indoor Vertical Farming
Keeping humidity levels right is key for plant health in indoor vertical farms. Humidity affects how plants breathe and absorb nutrients. Too much humidity can lead to fungal diseases, while too little can stress plants, causing them to grow poorly and yield less.
C3 plants, like most crops, do best with a Vapor Pressure Deficit (VPD) between 0.65 to 1.25 kPa. Leafy greens prefer the lower end of this range. On the other hand, fruiting plants like tomatoes and cannabis need a higher VPD as they grow. If VPD drops below 0.65 kPa, plants struggle to breathe and absorb CO2. But, if it goes over 1.25 kPa, plants get stressed.
Good humidity management helps plants take in water and nutrients well. It boosts their ability to fight off diseases and carry out important functions like photosynthesis. In the early stages, plants need a humid environment of 70 to 80% RH to grow roots. As they grow, the ideal humidity shifts to 50 to 80% RH, then drops to 40 to 60% RH when they flower.
Successful indoor vertical farming depends on monitoring and controlling the environment, including humidity. This not only keeps plants healthy but also boosts crop yields. It shows how important it is to understand humidity’s role in vertical farming systems.
Understanding Relative Humidity and Its Role
Relative humidity (RH) is key in indoor growing, focusing on controlling humidity. It shows how much water vapor is in the air compared to what it can hold at a certain temperature. Keeping RH between 40-60% is vital for most indoor plants’ health.
High humidity can lead to diseases like botrytis, harming plants like cannabis. These plants have dense buds that trap moisture, making them prone to mold.
The dew point is also important for growers. It’s the temperature when air is fully saturated with water vapor, causing condensation. High RH and cool temperatures can lead to condensation on surfaces, raising mold risks.
Managing dew point is essential in grow spaces. Good humidity control stops moisture buildup on ceilings, walls, and plants.
Knowing how humidity, temperature, and dew point work helps growers improve their growing space. For example, during propagation, RH should be 85-90% to help roots grow well. As plants get older, RH should drop.
Young plants do well at an RH of 65%. But too much humidity can stress them, causing them to stretch. On the other hand, RH below 45% can mean the air is too dry, stressing plants.
To find the right balance, growers need to understand their setup and the season. They might need to add or remove humidity based on plant needs and the environment. Using a humidifier with a humidistat is easier than removing moisture, which might need a dehumidifier and a Dehumidistat.
Humidity Level | Stage of Growth | Recommended Action |
---|---|---|
85-90% | Propagation | Maintain high humidity |
65% | Early Vegetative | Encourage nutrient uptake |
55% | Late Bloom | Ensure denser flowers |
Below 45% | General Health | Address dry air issues |
Humidity Control in Grow Vertical: Best Practices
Keeping humidity levels right in grow vertical systems is key for great yields and healthy plants. Knowing how to measure humidity and find the best RH for vertical growing boosts indoor farming’s growth and efficiency.

Common Causes of Excess Humidity in Grow Rooms
Excess humidity in grow rooms comes from several sources. Overwatering plants is a big one. It makes the air too wet. Also, not enough air movement makes the air stay wet for too long.
Plants release moisture through breathing and from the soil. At night, this moisture can make the air very wet. This is bad for plants and can cause diseases like powdery mildew and botrytis.
Grow areas need good air flow to stay healthy. Using dehumidifiers, like those from DryGair, helps keep the air just right. They can pull out a lot of moisture, keeping plants happy.
In places with lots of plants, the air can get very wet. It’s important to control humidity day and night. This stops mold and helps plants grow well. Using the right methods to control moisture is key.
Techniques to Lower Humidity Levels
Keeping humidity levels right is key for healthy plants in vertical farms. Using certain methods to lower humidity can greatly help. This ensures plants grow well.
Avoiding Overwatering
One important way to avoid too much humidity is not to overwater plants. When you water too much, the air gets too moist. This can lead to diseases. Here’s how to keep the right amount of moisture:
- Make sure containers have good drainage to stop water from pooling.
- Water plants when the light is on and let the soil dry a bit before watering again.
- Keep an eye on how your plants and soil are doing. This will help you water just right.
Improving Air Circulation and Ventilation
Improving air flow helps lower humidity. Fans help move air, but they don’t cut down humidity. Here are some better ways:
- Put vertical fans and air circulators in the right spots to spread out humidity.
- Use dehumidifiers. They lower humidity, control temperature, and save on energy costs.
