How to Increase Humidity in Greenhouse

To grow plants in a regulated climate, if you are planning to cultivate in a greenhouse, then having information and increasing humidity would be an added advantage to you. As you know, a greenhouse, known as a glasshouse and a hothouse, is an excellent place to grow plants. In this system, plants are grown in a controlled climatic condition.

These greenhouses are constructed in different sizes. As per your necessity, you may choose a greenhouse of small or medium or industrial-building size. However, to maintain humidity and temperature in the greenhouse, you will surely aspire to take the right steps. Due to the vapor that comes from the moist soil in the day time, humidity in the greenhouse increases. However, regulating the humidity will be necessary for you to cultivate flower plants, crops, or vegetables in a greenhouse. 

Ideal Humidity in a Greenhouse

Ideal Humidity in a Greenhouse

Let you reveal the ideal humidity in a greenhouse. Regulated humidity is an important aspect behind the faster growth of plants in a greenhouse. Growers find 50 to 70% humidity at the best humidity level. However, greenhouse plants may tolerate humidity from 60 to 80%. So, you would have to take proper initiatives to regulate humidity as per the requirement.

Various options are available in this aspect, but you cannot apply a single one until you get familiar with them. The process of watering plants, as well as temperature, plays a pivotal role in increasing humidity. Therefore, when you follow a proper step to combine temperature and watering in a calculated way, regulating humidity would be easier for you.


Heating and Ventilation

The temperature of a greenhouse matter a lot. What is the ideal temperature in a greenhouse? 80 to 85 degrees Fahrenheit is the best temperature of a greenhouse that helps growing plans in a faster way. By regulating the heating and ventilation from time to time as per the requirement, you can gain a great benefit in meeting your cultivation needs. In a greenhouse, not only humidity but also heating and ventilation also play a crucial role. Learning the way to control the temperature in a greenhouse is of utmost importance to a grower.


Why Do Greenhouses Need Ventilation

To cultivate crops or vegetables or flower plants successfully, you should understand the importance of ventilation apart from the heating process of a greenhouse. You will discover many significant roles in the ventilation system in a greenhouse. 


  • Controlling Temperature:   It seems that plants die due to cold in a greenhouse, but this is though true yet, you should know that most of the plants due to overheating. In this context, the role of ventilation is immense. For proper maintenance of temperature here, you should have to arrange the right ventilation system.


  • Humidity Control: The next important role, played by ventilators, is humidity control. Through transpiration, plants tend to give moisture in the air. If this moisture remains in the greenhouse, then the humidity will increase naturally. As far as you know, a greenhouse with less humidity in the air slows down the growth of a plant; 
  • Overmoisture is also creating trouble for the plants. Controlling humidity becomes easier with proper ventilation.


  • Allows Fresh Air:     Airflow is another important part that adds to the growing process of the plants in a greenhouse. If proper ventilation is not allowed, then fresh air will not come into the greenhouse, causing a deficiency in carbon dioxide. Lack of carbon dioxide in the air would hamper the growth of plants in a greenhouse. 



  • Pest Control:     Poor ventilation is a great reason behind the increased number of harmful pests in greenhouses. Bugs and such pests find a closed greenhouse as a comfortable place to grow. Therefore, to eliminate this problem, ventilation provides a good solution. You will discover ventilation as a fabulous tool to grow plants in greenhouses. So, let it get a proper position in the list of techniques for running a greenhouse successfully.


Condensation in Mini Plastic Greenhouse

Condensation is when water vapor changes its form from gas to liquid and becomes water. Due to the cooling down of water vapor, condensation occurs. Getting the touch of colder surfaces such as aluminum frame, iron pipes, plants, water vapor changes its form and becomes water. To stop condensation, you would have to take a better step to water the plants.

Watering at proper quantity as per the floor space would be highly beneficial in this context. When lesser moisture occurs, lesser condensation will happen. In the mini plastic greenhouse, condensation occurs more. To eliminate such difficulty, taking proper measures of ventilation as well as watering will give fruitful results. Cultivating without any problem will become possible for the growers. You will also aspire to follow the way, which will help you overcome the condensation in greenhouses.

After determining when to plant Mexican heather, you must prepare the site for your plants. Remember that the location is crucial to guarantee the steady growth of any plant. Therefore, you may benefit from starting Mexican heather indoors if your climate is fluctuating. 

In general, you want somewhere with fertile and well-draining soil. Test your soil to do the necessary amendments and improve its structure. The plant also does best with some shade because the full sun affects the foliage’s health. 


Step #2. Planting

After you started Mexican heather in the greenhouse, gently take the plant from the pot. Make sure to untangle and loosen the roots before setting the plant in the center of the hole. Allocate a space of three feet between each plant, and the top of the root ball should be half an inch above the ground. 


Step #3. Maintenance

Maintaining the newly planted Mexican heather plants is no different from other plants. You want to keep soil moisture to help the plants establish themselves. However, be sure not to create a wet environment that can decay the plant. 

Adjust your watering practices according to the weather. Mature Mexican heather plants will tolerate challenging conditions like drought and summer heat. However, it’s best to provide two to six hours of partial shade instead. 



How To Propagate Mexican Heather



You can grow Mexican heather from seeds similarly to other flowering plants. Use pots with standard potting mix for sowing, and then add some soil over the seeds. Maintain soil moisture, and you can place the pots in the greenhouse to protect the seedlings from the environment. 



You can also root cuttings from a healthy Mexican heather plant. Take a four-inch stem section, remove its lower leaves, dip the end in rooting hormone, and then plant in a pot with soil. Continue watering until root establishment for transplanting. 



Division is an excellent way to grow Mexican heather and also keep the plants from overcrowding an area. Gently loosen the soil around a plant to make lifting easier and divide the root ball into sections using a sharp and sterile knife. Depending on its size, you can get up to four divisions for transplanting in containers or onto the garden. 


Caring For Mexican Heather


Water and fertilizer

While Mexican heather can tolerate dry conditions, it would still be optimal to keep them well-hydrated. You can water the plants deeply once per week, but ensure that you’re using a well-draining medium and container. Then, wait for the ground to dry in between waterings to avoid creating standing water. 

Remember to adjust the frequency and amount of water you give to the plants. More so, container Mexican heather plants would dry faster, so water them often. You can also mulch every spring to maintain soil moisture and even smother weeds. 

Do you fertilize Mexican heather? Mexican heather is relatively low-maintenance and not meticulous when it comes to nutrients. However, you can still boost and maintain your plant by fertilizing in spring, summer, and fall with a balanced feed. 



Pruning is not a requirement for Mexican heather. However, you can maintain the size and shape of your plant by trimming lightly every spring. You can also use this practice to remove the unhealthy parts.
