The Best Flooring for a Greenhouse  (Includes Benefits)

Greenhouses are becoming increasingly popular with gardening enthusiasts as they help create and maintain a personal micro-ecosystem.

They offer you better control over the temperature and humidity. Thus, enabling you to expose your plants to ideal growing conditions. While the material you choose for your greenhouse plays a significant role, the flooring is also quite substantial.

The best greenhouse flooring will offer good drainage, easy maintenance, insulation properties, and durability and serve as a weed barrier to keep weeds and pests. Moreover, the flooring can improve the greenhouse space’s overall look, feel, and productivity.

A greenhouse is a closed structure with specific dimensions and a roof made of transparent glass or translucent plastic sheets.

The kind of flooring you choose for your greenhouse plays a significant role as it helps manage the overall atmosphere. It usually depends on how you wish to grow your plants.

It should be noted that flooring is the foundation of your greenhouse, and it can make your gardening experience much more fulfilling and rewarding.

Best Greenhouse Flooring Options

Soil Flooring

Farmers or gardeners new to greenhouse farming can consider soil flooring, which works best for small and compact greenhouses.

People who wish to dip into the world of greenhouse warming can use soil for flooring as it can be installed without putting in much effort, money, or time.

Moreover, growing fruits and vegetables directly on the ground will be easier, mainly if used in traditional farming practices. You can grow avocados and tomatoes on this kind of flooring.

However, you would not have proper flooring. So, you can employ pavers, gravel, flagstone, or wood planks to create walkways if required. While it will give your greenhouse a much cleaner look, it will also help drain excess water.

Concrete Slab

Many people are opting for a greenhouse that has a concentre slab laid down on the floor, and this is because it is straightforward to install and maintain.

Make sure to find a contractor with expertise in concentre slab installation. By doing so, you will have a long-lasting floor that does not cause structural damage to the ground.

While this option can be pretty expensive, it truly justifies the price as it is also one of the most durable and low-maintenance flooring options.

Moreover, you can install benches on a concrete slab as this flooring can bear the weight of heavy furniture without any issues.

After installation, you will transport seeds, fertilizers, and other farming tools in a wheeled car, as the concrete slab will provide smooth ground. Also, building the slab at a slight slope is recommended to ensure proper drainage.

Rocks and Pebbles

In today’s day and age, greenhouses do not have to be designed simplistically. This means you can keep your greenhouse’s flooring aesthetically as your heart desires.

Utilizing rock and pebbles to cover the greenhouse ground will be an excellent choice. Not only will your conservatory look beautiful, but its flooring will be a breeze.

The installation of rocks and pebbles on a greenhouse floor is a task that can be done without any external help.

All you need is a good number of stones and pebbles from a contractor; the remaining process can be done in-house. 

To prep the sight, you need to remove weeds, if any. Also, put a weed mat before placing pebbles to ensure weeds do not sprout.

One of the most affordable ways to make your greenhouse floor durable is by putting gravel over the ground. Other than being an inexpensive option, it can also improve drainage. Various gardeners swear by this kind of flooring because of its benefits.

One thing to remember is that a polypropylene ground cover should be placed below the gravel. This is mainly to protect your greenhouse from weeds.

Once the polypropylene cover is placed on the ground, you do not worry about unwanted plant growth. It will also save you the expenditure of buying weedicides. Because of these benefits, most gardeners prefer gravel as their greenhouse floor.

Bricks have played a massive role in the construction industry for a long time. This is simply because bricks can withhold natural calamities such as earthquakes, storms, cyclones, etc.

Remember, bricks can be a wise option for your greenhouse floor.

Creating single-layer brick flooring is highly recommended if a small area is allotted for your greenhouse. For gardeners planning to develop a large-scale greenhouse, multiple layers of bricks should be installed to provide solid and sturdy flooring.

On a technical level, bricks benefit conservatories as they can absorb water. As a result, there will be optimum humidity inside your greenhouse, which will work wonders for the growth of your fruits and vegetables.

Aesthetically speaking, bricks provide a rustic look to a greenhouse that can be pretty eye-pleasing. 

Vinyl Covering

Vinyl flooring in a greenhouse is suggested to farmers and gardeners in the commercial business on a large scale. This is mainly because of the affordability guaranteed in this type of flooring.

You can secure a vast area without spending a lot of capital. So, looking for contractors with a solid reputation for installing commercial vinyl covering on a greenhouse floor is advised.

You may be able to come across a vinyl coating that is UV-resistant, anti-microbial, and anti-bacterial. Another benefit that you will be able to enjoy is that this type of flooring is water-resistance. Hence, you will not have any unwanted growth on your greenhouse floor.

Benefits That Your Greenhouse Flooring Should Offer You

While planning the flooring of your greenhouse, you must have a complete idea about the benefits it can offer you. Here are some of the benefits that your greenhouse flooring should provide:

Proper Drainage

Greenhouses typically have wet and humid environments, so ensuring that your flooring choice offers proper drainage is essential.

And if you are installing solid floorings like concrete, wood, or mortar stone flooring, you should also consider installing a drainage system.

This will ensure that the greenhouse is not slippery, which can be dangerous.

Not to mention, constantly wet flooring can promote mold and fungus growth.


Imagine having a small to medium-sized greenhouse that you wish to expand. In this case, you need flooring that can be easily installed and re-installed during the reconstruction process.

Hard flooring that will not mold in a larger area can be a big problem. Thus, it would be ideal to adjust the flooring according to your future aspirations and needs.

Also, it is advised to consider how you wish to grow plants in your greenhouse. This will help you pick a flooring option that caters to your needs and reduces the probability of future changes. So, deciding whether you wish to grow directly in the soil, on raised beds, or in an aquaponic or hydroponic system is better.


The purpose of building a greenhouse is to diminish the influence of the environment in a particular region.

For instance, you might be living in an area where the temperatures are too cold to grow plants at all, but with the help of a greenhouse where temperature control can be managed according to the needs of your crops, this issue will not be relevant to you.

Insulation is a critical factor in this regard, as greenhouse flooring should be secure enough to keep the influence of outside temperature away.

With sturdy and highly insulated flooring, your fruits and vegetables will grow without getting affected by the climatic conditions outside the greenhouse.


Durability is another significant benefit that the right flooring can offer. Greenhouse flooring that offers long-term durability is the right choice to keep the ground stable and weed-free.

With this benefit, you will operate systematically and concentrate on your crops without worrying about the flooring. It is suggested to install flooring that has been tried and tested before.

You can review reviews and ratings of other greenhouse farmers, and their experiences will help you understand the pros and cons of each available flooring. In the end, you will be able to make the correct choice.

Easy Maintenance 

The worst fear of a gardener is spending excessive money on the greenhouse’s maintenance. Repairing the floor can be a big issue as it can drain your capital quickly.

Thus, choosing a type of flooring that does not require constant repairs or replacements is recommended.

The wise thing to do is buy affordable greenhouse flooring, ensuring that any damages can be mended without high costs.

Repels Pests

The type of flooring you choose can also play a significant role in determining whether your greenhouse is free from pests and weeds. While some flooring options attract pests, some repel them. For instance, flooring options like sawdust and mulch decompose with time as they are organic.

While decomposing, they can offer a breeding area for pests and algae. So, if you are growing a plant that is often vulnerable to problems, you must avoid these options. Instead, you can go for flooring options like concrete and stone.
