How to Keep Plants Warm Inside a Mini Greenhouse

Perhaps one of the things that you want to figure out is how to keep plants warm inside a mini greenhouse. If you’re new to mini greenhouse gardening, you can be confident that these enclosed spaces are ideal for providing your plants with the protection that they need during those cold winter months. However, when the temperatures begin to drop lower than the usual, you’ll need to provide your crops with extra heat.

If you think that the measures that you need to take to make this happen would require the use of electricity, think again. Here are some of the frequently asked questions about keeping plants warm inside a mini greenhouse:

How Do I Keep My Mini Greenhouse Warm?

You need to prevent the heat from escaping the confines of your mini greenhouse during those cold winter nights. The good news is that you won’t have to break the bank to make this happen. Check out the best ways you can keep your mini greenhouse warm:


Use a horticultural bubble wrap

One way to do this without breaking the bank is to insulate your mini greenhouse with the use of horticultural bubble wrap, which you can easily find at the nearest garden center. Keep in mind that the regular type of bubble wrap won’t be strong enough to withstand ultraviolet rays and provide your plants with the protection that they need. It’s important to note that using horticultural bubble wraps with bigger bubbles can insulate your plants better.


Fill glass bottles with water

Another way to do this is to make use of glass bottles and filling them with water. During the day, these water-filled bottles work to absorb the heat from the sun so that they can release it back to the plants during the night.


Keep your mini greenhouse well-ventilated

Since plants release oxygen and moisture after they make use of CO2, they tend to deplete their growing environment from CO2 and encourage the growth of harmful mold, mildew, as well as fungus. For this reason, it’s best to ensure that your mini greenhouse is well-ventilated. To do this, you’ll need to open your greenhouse vents during the daytime and close them at night.


Raise your plants off the ground

Since the ground becomes cold during winter, you could help keep your plants warm if you keep them off the ground. Try placing a single layer of clay pebbles at the bottom parts of your pots.


Do Mini Greenhouses Need Grow Lights?

When you’re growing plants in a mini greenhouse, keep in mind that nothing could ever compare to natural light. However, you may need some supplemental light if you’re trying to grow your plants in the middle of the winter season or if the placement of your mini greenhouse doesn’t allow your plants to get enough sunlight. Keep in mind that you need to be careful in choosing the type of grow lights you use because getting the wrong ones may negatively affect the growth of your plants.

How Much Light Is Needed in a Mini Greenhouse?

Generally, mini-greenhouses need about 6 hours of full-spectrum or direct light on a daily basis. If this can’t be achieved with natural light, you must consider using supplemental lighting. In case you’re wondering, supplemental lighting encourages crop growth, as well as yield with the use of multiple and high-intensity artificial lights.


Can You Have a Mini Greenhouse Indoors?

Of course, you can!

If you get yourself a mini greenhouse, you can grow just about anything you want. Contrary to what you may have initially thought, setting up a mini greenhouse in your apartment or rooftop will only require very little care. To create the ideal growing environment for your plants, you can also add temperature and humidity controls, as well as grow lights.


Should I Invest in a Mini Greenhouses?

Yes! Investing in a mini greenhouse is definitely worth it because it offers several benefits for you and your plants. Check out the reasons why you should invest in a mini greenhouse:


You can use it even with limited space

Since mini greenhouses are far from being space-hoggers, they work best for gardeners with tight living spaces. What’s more, you can easily move these enclosed spaces around if you need your plants to get more sun or to move them to shaded spots throughout the day.


Your plants can maximize their growth potential

One of the best things about mini greenhouse gardening is the fact that you’ll be able to create the ideal growing environment for your plants all-year-round. Unlike traditional outdoor gardening, which causes your plants to be exposed to harsh weather conditions, pests, and destructive animals, a mini greenhouse offers them the protection that they need. What’s more, mini greenhouse gardening also allows you to control the levels of temperature and humidity inside the enclosed space.


It’s excellent for growing sensitive plants

A mini greenhouse makes it easier for you to grow sensitive plants that have their own set of unique needs. For example, you can keep your orchids well-satiated if you grow them in a mini greenhouse that provides them with enough shade, as well as a well-aerated soil that promotes good drainage. Even when the weather outside isn’t favorable to your orchids, you won’t have to worry about temperature swings.
