What’s the Ideal Grow Tent Temp & Humidity
Before anything else, it’s essential to know what’s the best grow tent temp and humidity level for your plants. For different stages of plant growth, the preference differs as well. To save you time, we prepared a grow room temp and humidity chart that illustrates the ideal metric for each stage.
Once the humidity goes beyond the suggested level, what will happen? Possibly, you’ll encounter the following situations:
- Mold and Mildew Growth: Excess moisture in the air creates a favorable environment for mold and mildew. These fungi can spread throughout your grow tent, damaging plants, and creating moldy weed.
- Pest Infestations: High humidity can attract pests such as spider mites, fungus gnats, and whiteflies. These pests thrive in humid conditions and can quickly infest your plants, causing damage and inhibiting growth.
- Reduced Nutrient Uptake: High humidity can affect the plant's ability to absorb nutrients effectively. It can lead to Cal-Mag deficiency, stunted growth, and overall weaker plants.
- Root Rot: Excessive grow tent humidity can saturate the growing medium, leading to poor oxygenation and root rot.
- Flowering Issues: High humidity during the flowering stage can hinder proper pollination and the development of healthy flowers. It may lead to poor yields, malformed buds, or decreased potency.
Bet you don’t want to experience any of these, so, how to lower humidity in grow tent?
How to Lower Humidity in Grow Tent
Use a Dehumidifier Inside Your Grow Tent
Frankly speaking, the most effective and effortless way to reduce humidity is by using a dehumidifier. The only downside lies in the cost.
A dehumidifier is a device that extracts excess moisture from the air, helping to reduce humidity levels in the grow tent. It works by pulling in air, cooling it, and collecting the moisture before releasing the drier air back into the environment. By using a dehumidifier, you are guaranteed precise humidity control and improved air circulation.
However, if you don’t want to invest in a commercial dehumidifier, there are plenty of ways to lower humidity in grow tent without spending too much. Let’s see how to lower humidity in grow tent without dehumidifier.
Prevent Overwatering Your Plants
To decrease humidity levels in your grow tent, it is quite important to avoid overwatering your plants. Overwatering leads to an excess of water, which can elevate humidity levels beyond the appropriate range. Additionally, saturated soil can result in extra water in seed starting trays, further contributing to increased humidity levels. To avoid overwatering cannabis, simply water according to plant needs, not a schedule.
Check the Plant Density to Improve Ventilation
Plant density has a significant impact on the humidity levels in your grow tent. As plants release carbon dioxide, the temperature within the tent rises, leading to moisture buildup and increased grow tent humidity. You may want to reduce the number of plants for proper air circulation and carbon dioxide distribution. If removing plants is not an option, consider relocating only those with large leaves.
Remove Stagnant Water
You may not realize, but stagnant water on the ground can contribute to excessive humidity. What’s worse, when water remains stagnant, molecular oxygen is reduced, providing an environment for bacteria to thrive. By removing still water, you can not only lower humidity in grow tent but also prevent bacteria from growing.
Enhance Ventilation with Inline Fans
Improving ventilation by adding inline fans is an effective way to increase airflow in your grow tent and lower humidity. By facilitating airflow, inline fans assist in regulating temperature and humidity levels. They can help remove excess heat and moisture from the grow tent, preventing heat stress and promoting optimal growth.
