Turn A Room into An Indoor Greenhouse

Trees are an inseparable part of our earth, and day by day the numbers of them are gradually decreasing. Although there are many moves to plant more trees but we all fail due to the lack of space. Many people who love gardening are also unable to build their own garden due to inadequacy of fertile land. Even though it holds true that we are lacking space, we still can use the unwanted or unused spaces of our house to create a safe haven for the plants.

Many people may argue that planting trees indoors not only ‘wastes’ space, but the plants will eventually die off due to inadequate sunshine. This, however, is not true. There are plants which grow even with little or no sunshine, so you don’t have to worry about your investments dying off overnight. As for the ‘waste’ of space, a study by NASA showed that indoor plants can remove toxic agents such as benzene, formaldehyde and trichloroethylene from the air, helping neutralize the effects of sick building syndrome.

This is why we all should focus on using the very little space we have to make sure that we are breathing in ‘pure’ air. To do this, you must know how to convert your unused room into a mini indoor greenhouse. Follow the simple steps to make yourself your very own indoor greenhouse.

Step One: Choose Your Space

The first step to your indoor greenhouse DIY is to choose the space where you’d grow your plants. Dedicate the room solely for the gardening purpose. You can use any room that you don’t normally use. This can be a room that is next to your living room, or the basement of your house. It doesn’t really matter which room you use. Just keep in mind that the room MUST have a proper ventilation and pets should not be allowed to enter the room.

Step Two: Choosing Your Medium

After you have your room sorted out, you must decide on the process of gardening. What this means is that you have to decide whether you would use soil or hydroponic system for the plants. Hydroponic systems require less space and less water when compared to regular soil, but has to be regularly fertilized.

Prior to the start of your gardening, you must research about which growing methods you are going to use.

It is recommended that you add the best quality fertilizers to your medium as this directly affects the growth of your plants.

Choosing Your Medium

Step Three: Preparing Ventilation

During your gardening, you must ensure a continuous air flow. Proper ventilation reduces heat within the room and helps to control humidity, which reduces the chance of pathogenic infection within the plants. You can get a continuous air flow by installing table fans and/or an air conditioner inside the room.

Preparing Ventilation

Step Four: Prepping the Walls

Although the walls are not that important when you’re gardening, you can maximize the effectivity of your small indoor greenhouse. To take the full advantage of your space and illumination, you can install some reflective materials on the walls of your room. This will prevent any light energy from being wasted. People often use mirrors or bubble insulation while prepping their walls of the grow space.

Step Five: Light Management

It is recommended that you do some research about the illumination of your room. As there is a lack of sunshine within the room, you must ensure that you are putting your resources in providing an alternative for the natural sunlight. Many indoor greenhouse gardeners prefer the following types of lights for their grow space:

  • LEDs
  • High-pressure sodium (HPS)
  • Fluorescent Light Bulbs

Step Five _ Light Management

A high quality HPS or LED bulb may have a built-in fan which cools the system down. A fluorescent bulb lacks a fan, so extra fans are needed to cool the bulb. Another study by NASA suggests that an LED bulb has the required wavelength for the best growth of indoor plants.

After you’ve decided on which lighting system to go for, decide as to where to put it. This is important because you must ensure that all the plants inside your room is getting sufficient light. When hanging the lights to the ceiling, it is a wise decision to use adjustable chains so that when your plants grow, you can increase the height of the light bulbs.

Step Six: Climate Control

Apart from air and light, there are some key aspects you should focus on when you’re focusing on the indoor climate of your grow room. These include temperature, humidity and carbon dioxide. To control these aspects, you can use the following indoor greenhouse kits:

  • Fans
  • Carbon dioxide generators
  • Light Timers
  • Humidifiers
  • Dehumidifiers
  • Thermometers
  • Humidistat
  • Thermostat

Climate Control

The temperature and humidity of your room will vary significantly depending on the climate of your area. This is why you must focus on controlling these two aspects so that the desirable temperature and humidity for the growth of the plants are achieved. Ideally you should achieve a temperature of 18° to 26°C and a humidity of 30 to 50 percent.

Step Seven: Planting

After you’ve finalized your choice of the medium, lighting system, ventilation and climate control mechanisms, you can start placing your plants. You can use regular pots or containers for the plants, but it is recommended that you use collection racks and screens as it elevates your grow area. By doing this, you can easily collect all the spills and debris that collects at the bottom of the racks and prevent any infection of plants. This also enhances the air flow for the plants.


Step Eight: Maintenance

Abandoning the plants completely is not a wise thing to do as it may cause the plants to die out. You must regularly check the humidity and temperature of your indoor greenhouse. You must also pluck out all the unnecessary weeds and trim the leaves of plants. We recommend using a high-quality trimmer rather than doing it by hand as it will increase the beauty of your indoor plants.


Building your own indoor greenhouse is as easy as it seems. If you follow the steps mentioned above, you’ll be able to build your indoor greenhouse just like a professional. The indoor plants not only increase the beauty of your house as a whole, but also provides fresh air and removes toxic agents from the air. Keeping all the benefits of the plants in mind, you can surely follow the steps and create a marvelous indoor greenhouse that everyone will be jealous about!
