Factors That Keep Greenhouse Plants Small
Keeping greenhouse plants small is largely due to temperature and humidity, which we’ll explore in this section. Later, you’ll learn about some of the ways in which you might influence these variables. Let’s go into more detail so that you may better comprehend.
Temperature and humidity to maintain plant size
When it comes to the growth of your greenhouse plants, temperature and humidity are intertwined. Due to each of these conditions, greenhouse plants maintain their modest size.
The plant’s ability to retain water is affected by the temperature of the surrounding air. The higher the relative humidity, the more water vapor there is in the air. As a result, you can argue that managing humidity is dependent on temperature.
The amount of water vapor in the air is determined by the amount of relative humidity. It’s a measure of how much something has to be in order to be fully saturated. Biological processes, particularly transpiration, are impacted by this component.
In the process of transpiration, plants absorb water from their roots, transport it to their tissues, and expel it to the atmosphere through their leaves. It’s critical to the plant’s growth and development. In addition, it is responsible for discharging water into the atmosphere, which aids in the plant’s ability to stay cool.
Plants, too, may be referred to as sweating. You’d be uncomfortable if we sweated a lot in a humid environment, wouldn’t you? Your plant’s transpiration process is disrupted by high humidity in the same way that our sweat can’t evaporate. Your plant’s development will be jeopardized.
How to control humidity and temperature
Now that you have a better understanding of the factors influencing your plant’s growth, you need also take into account the environmental conditions outside the greenhouse.
Changes in the weather and temperature can be seen outside your greenhouse. To keep your plant healthy and growing appropriately, you’d want to manage the conditions inside.
You need to know how to control humidity and temperature to keep greenhouse plants tiny. So, how can you do that?
#1 For humid areas
In humid climates, passive and active ventilation are common solutions. As it pushes hot and cold air up and down, it regulates the temperature and humidity in such a place.
#2 For dry areas
Evaporative cooling, on the other hand, is the ideal choice in dry areas. Because the relative humidity is lower, ventilation alone will not enough. It works by supplying moisture to the greenhouse environment, which removes heat while allowing moisture to enter the greenhouse, evaporative cooling.
The system controlling humidity and temperature
Now that you’ve learned how to regulate the humidity and temperature in your greenhouse, you’re all set. Equipment must be used to keep greenhouse plants from getting too big.
The greenhouse’s humidity and temperature can be controlled using these additional methods:
#1 Use a fan and pad cooling system
A regularly used approach by plant producers incorporating a fan and pad system, a huge wet wall is erected on one wall, and a series of exhaust fan positioned on the opposing wall of the greenhouse. A water source allows the pad to continuously discharge water vapor.
The pad will then be used to channel the air. Using the exhaust fan, the moist and chilly air will be drawn into the greenhouse and expelled into the atmosphere.
It’s simple to use, and it’s also inexpensive. A mineral deposit and bacterial growth are potential problems with the pad, though. The pad-wall and fan-wall temperature gradients may be unequal.
#2 Use a high-pressure fog system
The technique makes use of nozzles that are evenly spaced around the greenhouse. Your greenhouse would thereafter be filled with an artificial fog thanks to a series of nozzles.
Pad and fan systems are not ideal for small greenhouses since they don’t offer the same level of coverage and consistency as high-pressure fog. However, there are certain drawbacks to it as well.
You need to control the size of your water droplet; smaller droplets are not adequate to provide the moisture your plant requires, and larger droplets may cause your plants to be destroyed.
Regardless of the size of the greenhouse, both techniques are equally effective. However, if you’re on a budget, shade curtains are an excellent option. When it comes to keeping the heat in, shade curtains can do the trick.
When it’s sweltering outside, it’ll help keep things cool by dissipating heat. If the temperature outside drops, you can manage the greenhouse’s temperature by hanging transparent curtains at night.
But use it wisely, as it may interfere with your plant’s photosynthesis and transpiration.
Covering Plants with Plastic Bags
Polyethylene bags keep plants from drying out, and they even trap the water they expel through the leaves. Succulents can withstand neglect, but not this level of dampness, so avoid using plastic bags as a greenhouse for them. If a sudden frost is predicted, you may want to bring potted flowering and fruiting shrubs inside to protect their buds. You can salvage the buds if the bush is small enough to fit a clean plastic waste bag over or around it. You can also use a plastic tarp or a sheet to protect larger bushes. If you just have a dark-colored bag, you can still utilize it. Remove the bags as early as possible the following day, especially if the weather is nice. Plastic magnifies the sun’s rays, causing your blossoms to swiftly go from the danger of freezing to the danger of scorching. When utilizing a plastic bag greenhouse, it is recommended that you place the container in a shady area. As a result, it’s best to keep the plants out of direct sunlight. When covering growing seeds with a plastic bag, be sure to let them a few brief glimpses of sunlight. Remove the plastic bag for an hour or so every few days in this case. To prevent damping off, check the soil moisture and allow the plants to get some fresh air. A fan and some fresh air will benefit plastic-covered plants, but interior heating won’t help them in most circumstances. Small pinholes in the plastic can also aid in air circulation while still supplying the essential moisture for growth.
Using a Plastic Bag Greenhouse
Maintenance and watering are the first steps in preparing your plants for life in a plastic grow bag greenhouse. Get rid of any fallen leaves. Pests should be checked for and treated if found. If pests and diseases are already established, the conditions are ideal for their growth.
You want your plants to be well-watered, but not drenched in water. Before putting them in plastic, give them a good watering. Excessive water should be allowed to evaporate or drain out of the container before using it. If you put a plant in a plastic bag with wet soil, the water will normally stay in the bag and the roots may rot. Plastic grow bag greenhouses are most successful when the soil is kept moist. Clear plastic bags can be used for a variety of additional purposes besides just protecting plants. Using chopsticks or similar sticks, some people avoid allowing the plastic to come into contact with the plant’s leaves. Experiment with utilizing plastic covers to protect your plants in a variety of settings, following the techniques outlined above.
Can I come in to the greenhouse?
Don’t be shy! The greenhouse is open to the public, and visitors are encouraged to stay and relax. When it’s cold outside, students take use of the loft’s extra room to concentrate on homework, read a book, or even take a little nap before class.
Can I store my favorite succulent/orchid/pet tarantula in the greenhouse? The climate seems so much nicer than in my dorm.
Having small guests is fun, but it poses a pest transmission issue. We ask that you leave your pets and plants at home in order to avoid any potential problems.
Can you take care of my plants over break?
We’re sorry, but we can’t offer break-time plant care.
Are there really lizards in the greenhouse?
Sometimes. Make sure to keep an eye out for one.
Can I do an experiment in the greenhouse?
The greenhouse is a popular place for students to conduct experiments, and we are delighted to accommodate their needs. Prior to starting any new initiatives, please inform the faculty administrator or student administrator.
Who works in the greenhouse?
Botany faculty and students oversee the operation of the greenhouse. In order to maintain a healthy environment, students are responsible for watering plants, coordinating projects, and implementing organic pest control.
If you assume that taking care of plants entails nothing more than giving them a daily drink, you’re mistaken. Growing plants in a greenhouse necessitates taking into account aspects both inside and outside the building in order to maintain a favorable environment for the plants.
Before you start building a greenhouse, remember to take into account the weather conditions in your area. To keep plants healthy, you need to make sure they have enough water, sunlight, humidity, and temperature.
Relative humidity is another another factor that helps greenhouse plants grow. If you want your greenhouse to grow, you’ll need to keep an eye on the conditions inside of it. We really hope that our responses to your inquiries were helpful. Thank you for taking the time to read this.
