Indoor gardening is one of the most significant issues for gardeners. When it was about gardening in a grow tent, it’s more important for indoor gardeners to control some issues. In this purpose, how to control humidity in grow tent and also provide you with measures that will help you to protect your plant from dampness and drying out.
If you want to raise your plant indoors, there are few things you should take into consideration. Unfortunately it’s true when you raise them in a grow tent.
Grow tents gives you an opportunity to take care of plant varieties over year without minding of the seasons. With them, you can grow any plant regardless of the climate zone or weather conditions.
The Grow tents help you, to have a controlled environment which even allows you to make use of hydroponics instead of the conventional soil.
Further, one of the major benefits of grow tents is that they provide a more efficient environment for nutrients absorption by the plants. The humidity in grow tents also bay all potentially harmful elements such as parasites, mod, extra dirt and insects larvae and that would harm to your plants.
Furthermore, Most indoor gardeners put together such as seed, fertilizers, growth PH and system cleaning overlooking humidity of the grow tent. The Moisture in the air is an essential factor; you should keep in your mind to make sure you have healthy plants.
For you kind information this article will take you through the role humidity plays in the growth of plants. And all steps you should take to raise the humidity in grow tent, in case the levels go too low. Since too high humidity is dangerous for your plants. For this, you should needs to learn how to lower humidity in grow tent?
Importance of High Humidity
Mainly, you should expose your plants to relatively high humidity is that they need water to be alive. Though they can absorb water through the roots, it is good to know that they also get water through other parts such as leaves and the stem.
To be more specific, plants also absorb water in the form of water vapor in the air through their stomata (tiny opening on the leaf surface). If there is no humidity or too little of it in the surrounding environment, the plants will lack the opportunity to get enough water for their full growth and development.
Have you ever asked yourself why many gardeners start their seedlings in propagators? Ask no more! Propagators are always sealed concentrating moisture around the tiny plants. This means that in a high humidity environment, your tiny or tender seedlings will focus on growth and development without stressing their minuscule root systems.
With the knowledge that the baby plants are in their most critical growth phase, you should provide them with optimum humid conditions before weaning them or hardening them off for outdoor conditions.
Why Low Humidity not good for your Plants?
Actually, Low levels of humidity of inside a grow tent will lead the poor growth and development of your plants. And it’s happens, when low moisture on the surface of the leaves forces the plant to exert extra pressure something that would shorten its life.
If more pressure is exerted on the root to absorb extra water and cater for humidity deficit, the plant becomes stressed leading to stunted growth. Dehydration in plants also results in stomata closing, which means that the plant will be unable to take more water if any.
The other impact associated with low levels of humidity in a grow tent including the possibility of plant desiccation. If the plant is desiccated, it becomes exposed to infestation by insects such as spider mites, mildew, and molds.
The reason why such plants are so vulnerable to pests and diseases is because they are more favorable and also offer a subsidiary environment for parasites and other organisms to take advantage of and flourish.
Studies also suggest that lack of enough humidity in leaves surface lead to extra absorption in the roots. When too much water is taken through the roots, it comes along with excess nutrients that would cause burns on the tips of the leaves.
Is Too High Humidity Dangerous?
High humidity is required for optimum health and growth of your plants, but at extremely high levels, it would cause more harm than good. The high humidity in grow tents is not recommended for the following reasons:
- Creates a perfect environment for the growth of molds
- It prevents effective transpiration for your plants
- It creates a conducive environment for bacteria growth
- Encourages unwanted biological growths
- It clogs the stomata reducing carbon dioxide intake which is necessary for photosynthesis
- Makes the roots Latent by reducing their ability to absorb water.
How to Raise Humidity in Grow Tent
Already you know high humidity in grow tents is very important for the health of your plants. So therefore, keep humidity in your mind together with other indoor growth factors such as temperature, light, PH, and ventilation.
Below are measures you should take to increase humidity in a grow tent in case it gets too low:
Lower extraction fan setting
Knowing how to vent a grow tent is very important as it can help you control or manage humidity for your plants. Fans are very important in the grow tents since they allow the air to circulate well and get distributed to the plants.
Proper ventilation ensures that there is a perfect exchange of air in and out of the grow tent, ensuring that your plants get fresh air. This helps prevent harmful microorganisms such as bacteria and fungi from staying or increasing inside the grow tent.
During your grow tent setup, you should ensure that your fans are set at a moderate speed to conserve moisture at different stages of plant growth. If your fans are rotating at high speed, they will cause the air to dry faster than normal.
In addition, high-speed fans never allow the water vapor to settle on the surface of the leaves for absorption. This keeps the moisture away from the plants leading to desiccation or dehydration.
Apart from reducing the speed of the fans, reducing the number of fans can as well help increase humidity in grow tents. You should set your fans to make sure the humidity in plants up to 60 percent.
Lower the Surrounding temperature
How to use a grow tent perfectly can become difficult especially when it comes to temperature regulation. Knowing how to cool a grow tent is therefore important if you need to raise water vapor.
It is well known that cold air sinks at the bottom due to its high density than hot air. A lower temperature will undoubtedly mean that the air is relatively moist, thus making the air to have a significant amount of water vapor.
A high humidity in the growth tent can simply be achieved by reducing the temperature of the heater or by merely increasing the temperature of the air-conditioning unit.
Another way you can help increase water vapor is by lowering the light intensity of the ultraviolet (UV) light, provided that it is enough to facilitate water evaporation. Light intensity should not be a point of concern given that the young plants are not in need of that extra light.
To help decrease grow tent temperature, you may also use a swamp cooler; a device that cools down the air and elevates humidity levels concurrently. This device operates mainly when the temperature is excessively high and humidity very low.
Having larger plants in the grow tent
Having larger plants in the grow tent can as well help increase humidity levels. Some gardeners usually think that larger plants rob younger one of air, nutrients, and light. However, the reality is that larger plants contribute highly to the humidity inside the grow tent.
You should make sure not to overcrowd the larger plants as they will disadvantage the younger regarding nutrients and light.
Larger plants also undergo the process of respiration releasing final products including water vapor and carbon dioxide. This water vapor may be used to feed the smaller and younger plants.
Bigger plants also mean larger leaves and more stomata, which mean that the plants will release more water vapor after evapotranspiration. The smaller or young plants can use this water vapor.
Use a Humidifier
A humidifier helps increase grow tent humidity by generating a cool mist that is important for your plants. Humidifiers need to be controlled as leaving them in the grow tents can lead to extremely high humidity which is not good for the plants
Some humidifiers are regulated by in-built humidistat which enables them to automatically moisture in and out according to the plant needs. Good humidifiers come with a large tank enough to hold at least six gallons of water at a time.
Increase water sources in the grow tent
To help increase the grow tent humidity, you should increase water sources and distribute them wherever possible. You can achieve this by simply placing water trays next to the passive air holes or air intake tubing.
You can as well damp sponges and put the next to the growing trays. The heat from the air-conditioning system or grow lamp can slowly evaporate the water in the sponges adding more humidity on the grow tent.
When using water as a source of moisture, make sure you use clean water to avoid harmful bacteria or fungi that may affect your plants. Also, avoid putting damp sponges near fans and lighting materials.
Fans and grow bulbs are materials that use electricity and may short circuit when they come in contact with water.
How to Lower Humidity in Grow Tent
As we discussed earlier, high humidity is important for indoor plants but can harm them when it becomes extremely high. Below are some measures you should take to lower humidity levels in circumstances when they are too high to affect the growth of your plants:
Use a Dehumidifier
A dehumidifier helps lower humidity level by drawing any wetness in your grow tent. If you live in moisture areas, you may need a humidifier that is attached to a drain.
If you are raising your plants in areas with less moisture, you may turn off the humidifier and drain it whenever it is full.
Use an air conditioner
Aside from cooling the air, you can reduce humidity with use of ACs
Increase the number of fans
Adding more ventilation can help increase the amount of air from in the grow tent. You can add more ventilation by increasing the fan rotation speed or by increasing the number of fans.
Avoid overwatering the plants
Overwatering your plants will, of course, make the water damp or soggy. This result to more water that could elevate a grow tent humidity beyond recommended levels.
Defoliate a little
Plants with extremely large leaves or with a lot of leaves can increase humidity in your grow tent. If the levels go beyond the recommended level, you can reduce or cut down some leaves.
Use absorbent surface
Another major step you should take to reduce grow tent humidity is using soil that has the ability to keep water underneath. A good example is a sandy soil that minimizes the amount of water on the surface by minimizing evaporation rates.
Humidity is an important part when it comes to indoor gardening. You must take full control of the humidity and know how to raise it in grow tents.
All you need to keep in mind is two main things. Firstly, you should be aware of what humidity levels are best for certain plant varieties and each stage of the plant growth.
Secondly, you should know how to lower and how to increase humidity in grow tent to keep it at recommended levels. Humidity plus other factors such as PH, temperature, light, and cleanliness can help you raise healthy plants with high productivity.
