How To Grow Grass Indoors

Growing grass indoors can be a great way to bring the outdoors in and create a sense of belonging. It’s easier than you might think and it doesn’t have to take up too much space, either. I’m Monty Don, and today I’m going to show you how!

It’s all about creating an environment that your grass will thrive in – one with enough light, nutrients, water and air circulation. With these simple steps, you’ll soon have lush green blades of grass growing right inside your home. So let’s get started!

Selecting The Right Grass Type

Choosing the right grass type for indoor growing is absolutely essential if you want to be successful. It can truly make or break your dreams of a lush, green lawn flourishing in your living room! With so many varieties available, it’s important to know what goes into selecting the perfect grass for your space.

The most important factor when choosing an indoor grass variety is finding one that will thrive indoors – and this means taking special care when considering the kind of soil needed. Certain plants require different types of soils to grow best, so understanding which ones are suitable for growing indoors is key. To keep pests away from precious blades of grass, avoid using any conventional garden soils outside as they could bring unwelcome visitors with them!

Once you’ve chosen the right soil, look closely at other factors such as water requirements and amount of light needed. While some species may need more sunlight than others, all should have adequate access to natural lighting throughout their growth period. And don’t forget about watering: too much or too little can spell disaster for your new-found greenery! Balance is key here; making sure each blade gets just enough H2O without overdoing it.

Creating The Perfect Growing Environment

I’m sure we all want to create the perfect growing environment for our grass indoors, so let’s talk about what we need to consider in terms of lighting, watering, nutrients, humidity and temperature. Lighting is key to helping the grass grow, so you’ll want to make sure you have good lighting that’s suitable for the environment. When it comes to watering, you’ll want to make sure you don’t over-water as this can damage your grass. You’ll also need to provide the right nutrients to your grass, as this will help it grow healthily. Finally, you’ll need to make sure the humidity and temperature are at the right levels to give your grass the best chance of success.


Lighting is one of the most important factors in creating an optimal growing environment for grass. Choosing the right bulbs, depending on your plants needs, can make all the difference when it comes to a lush and healthy indoor garden. Generally speaking, you should look for full-spectrum grow lights that reflect both warm and cool tones – these will provide the photosynthesis needed for healthy growth. I always recommend investing in good lighting fixtures with adjustable arms so you can easily adjust them as your plants mature. Not only does this help prevent stretching or stunting due to too much light but also ensures every inch of your lawn receives ample illumination! With proper lighting, you’ll be able to enjoy watching your grass thrive indoors year-round!


Once you have the lighting all sorted, it’s time to turn our attention to watering. This is one of the most important aspects of creating an ideal growing environment for your grass – getting the amount just right can be tricky! To ensure your lawn gets enough moisture without becoming overwatered, I recommend adding fertilizer every two weeks and avoiding soaking or flooding with water. If you find that some areas don’t seem to be receiving as much irrigation as others, consider using a sprinkler system in order to spread out the coverage evenly throughout your entire indoor garden. Establishing a consistent watering routine will help keep your turf healthy and strong! Ultimately, when it comes down to keeping your indoor grass lush and vibrant, proper hydration is key.

Ensuring Adequate Lighting

Now that you have the perfect growing environment for your indoor grass, it’s time to make sure you give it enough light. Installing lights and choosing the right bulbs is crucial in order to get the best results from your plants.

Firstly, take into account how much space you have available – this will determine which kind of lighting system is best suitable for your area. Depending on whether you’re using a shelf or larger cabinet, consider installing fluorescent tubes, LED strips or even CFL bulbs.

Secondly, think about intensity – too little light can cause stretching and leggy growth while too much may burn your plants. You’ll need to calculate precisely how many lumens are required per square foot in order to achieve optimal growth without risking any damage.

Finally, don’t forget about duration! Just as with natural sunlight outdoors, ensure that your plants receive between 12-14 hours of artificial lighting each day for healthy development and lush coverage. To save energy costs whilst still keeping up with optimum levels of illumination, opt for timer switches so that the lights turn off automatically at night – just like nature intended!

Providing Proper Nutrients

It’s possible to grow grass indoors but it requires a bit of effort and dedication. Did you know that according to the American Society for Horticultural Science, if properly maintained indoor grass can look just as lush as outdoor turf?

One of the key elements to growing healthy grass indoors is providing proper nutrition. This means giving your plants the necessary nutrients in order for them to thrive. One way to do this is through fertilizing options such as liquid or powdery fertilizer. Fertilizer helps provide essential minerals and vitamins that aid in growth, so make sure to apply it on a regular basis. Additionally, soil amendments like compost can be added once per month or so to help boost nutrient levels.

The most important thing when growing grass inside is consistency – make sure to stick with a routine watering schedule and keep up with any other maintenance tasks such as weeding and mowing regularly. With enough care and attention, you’ll have beautiful green lawn inside your home before you know it!

Maintaining Adequate Water Levels

I’m often asked how to grow grass indoors, and one of the most important factors is maintaining adequate water levels. To do this, you’ll need to ensure you are watering your grass on a regular basis. It is also important to monitor the moisture levels in the soil, and make changes to the watering frequency if needed. To ensure the soil doesn’t become waterlogged, you should also consider some drainage solutions – such as adding gravel or sand to the soil. This will help the excess water flow, rather than sit and potentially cause damage. So don’t forget – regular watering, moisture monitoring and drainage solutions are key to growing healthy grass indoors.

Watering Frequency

Finding the right balance of water for your indoor grass is a crucial part to its success. Too little or too much can mean disaster for your lawn, so it’s important to get the watering frequency just right! Selecting the appropriate soil and containers will also play an important role in how often you need to water, as these materials are all capable of retaining different amounts of moisture.

When deciding on how often to water your indoor grass, start by doing a quick check each day – if the soil looks dry then go ahead and give it some H2O. You’ll soon learn what works best with your particular combination of soil type and container size. If possible, using a spray bottle rather than pouring directly onto the grass can help keep things more evenly moistened; plus, it gives you greater control over exactly where the water goes.

If you’re worried about overwatering try sticking a finger into the top few centimeters of soil (selecting one that allows drainage is key here) – when this feels damp but not soaked through it’s time for another drink! Just be sure to stop before reaching saturation point otherwise root rot may occur. With regular monitoring, patience and practice you’ll have lush green turf in no time at all.

Moisture Monitoring

Once you have the watering frequency sorted, monitoring your indoor grass’ moisture levels is key in keeping it healthy and happy. Knowing when to water can be tricky – especially as every soil type and container size will retain different amounts of H2O! A good rule of thumb is to check for dryness by sticking a finger into the top few centimeters of soil; if this feels damp but not soaked through then that’s usually a sign it needs another drink. You’ll want to avoid saturating the roots too much though, or else root rot may occur.

One way to help make sure you maintain adequate water levels without overwatering is to aerate the soil regularly. This simple process helps increase oxygenation and drainage, which are both essential elements for encouraging deep growth in your green turf. And while doing so, pay attention to how well your containers hold onto moisture – smaller ones tend to require more frequent watering compared with larger vessels. Keeping an eye on these two factors should give you greater control over exactly where (and when) the water goes each day!

So there we have it: selecting appropriate soils & containers plus regular moisture monitoring all play their part in creating a vibrant landscape indoors. With patience, practice and perhaps even some extra aeration thrown into the mix, you’re sure to have lush green foliage inside no time at all!

Drainage Solutions

Now let’s take a look at drainage solutions for maintaining adequate water levels. One of the most important things to consider when choosing soil is its ability to allow easy and efficient draining – this will help prevent mold from developing in your indoor grass as well as providing an environment where oxygen can reach root systems easily. It’s also worth noting that if you’re using containers, they should be equipped with holes or slits near the bottom so excess liquid can escape before it builds up too much. And lastly, make sure you factor in factors like pot size, type of plant and climate conditions when deciding how often to water – all these elements play a role in determining how quickly moisture evaporates!

Setting Up An Air Circulation System

Having put in the hard work to ensure that your indoor grass is receiving enough water, the next step is creating a proper air circulation system. This will help keep your grass healthy and thriving.

An important part of setting up an air circulation system for indoor plants lies in choosing fans with adequate power output. Make sure you pick one with quiet operation and easy installation if possible. You should also consider selecting materials specifically designed to reduce noise levels such as acoustic foam or rubber grommets. Another tip to make sure your fan isn’t too loud is to mount it on soft mounting blocks, which can be found at most hardware stores.

Air circulation systems are crucial for keeping your indoor grass alive and well-nourished, so take some time when deciding what type of fan to buy and how best to install it. With careful consideration, you’ll have set up a perfect environment for growing beautiful green turf indoors!

Controlling Temperature And Humidity

Temperature regulation is key to successful grass growing indoors – it’s important to get the balance of warm and cool air just right. Humidity is also important to consider, as too much or too little can affect the health of your grass. I’d recommend investing in a thermometer and hygrometer to make sure you’re keeping an eye on both temperature and humidity levels. With the right care, you’ll be able to create the perfect environment for your grass to thrive!

Temperature Regulation

At the heart of successful grass growth indoors is temperature regulation. The environment needs to be carefully moderated to prevent heat from becoming too extreme and cool temperatures from lingering, so that the grass can flourish in its artificial habitat. Controlling both humidity and temperature is vital for keeping the space comfortable enough for your grass to thrive – I always ensure my indoor area has a thermostat installed and set it to somewhere between 18°C-25°C. Additionally, I use an electric fan or air conditioner as needed to help regulate any spikes in temperature; this ensures my room stays balanced, preventing excessive heat while also moderating cooler temperatures when necessary. With these measures taken care of, you’ll have created an optimal growing environment and will soon see your grass flourishing!

Humidity Regulation

Humidity regulation is also a key factor in growing grass indoors. To succeed, you must choose the right soil and monitor moisture levels to ensure that your grass doesn’t dry out too quickly or become bogged down with too much water. I always opt for a potting mix specially formulated for seedlings and saplings – it’s lightweight and drains well, so you can rest assured knowing that your plants are getting all they need while not sitting in standing water! Additionally, I like to check my room’s humidity regularly; ideally this should be kept between 40%-60%, but if it gets any higher then I use an electric fan or air conditioner to help draw some of the extra moisture away from the area. As long as you keep monitoring these conditions, you’ll have created an ideal atmosphere where your grass will thrive!

Monitoring And Troubleshooting

I know it can be tricky to grow grass indoors, but with the right techniques and careful monitoring you can create a beautiful oasis in your home. Checking the soil is essential for healthy growth. Make sure that the pH balance of the soil is correct so that your plants receive enough nutrients. If necessary, use a simple test kit to check the acidity level of your soil regularly.

Another important part of growing grass indoors is keeping away pests. The last thing you want when trying to nurture your little patch of greenery is an infestation! Start by making sure any outdoor plants are well-tended, as these could introduce unwanted visitors into your indoor environment. Inspect all new additions carefully before bringing them inside and keep on top of regular pest control treatments if needed.
