Grow Bags vs. Plastic Pots - Benefits of Grow Bags (2024)

Many people think of agriculture as just one more industry. However, there is probably not a single other industry on earth as important as how we obtain our food. There is a reason that the value of the industry for agriculture, forestry, fishing, and hunting in the United States alone is worth more than$466 billion every single year!

Of course, experienced farmers learn to use all kinds of different tools to help them grow their plants. A farmer that starts with a 5 gallon plant pot might eventually start to experiment with garden bags. There are a lot of advantages to using planter bag options that not everybody is aware of.

So what exactly is so great about grow bags and how do they compare to plastic pots? Readon to learn all about the most important advantages that come with using grow bags!

Grow Bags Lead to Better Roots

There are a few things as essential to the success of a plant as the health of its root structure. Farmers have learned a lot of tricks over the millennia to improve root structure. However, many of those tricks can only do so much when the basic dynamic of roots growing in the earth is maintained.

Grow bags are a paradigm shift. They are a fundamentally different way for plants to grow.

Of course, it is one thing to appreciate planter bags in theory. It is very different to understand the real-world benefits torootstructures that they provide.

First of all, grow bags lead to more fibrous growth in systems of roots. These kinds of fibrous growths lead to better absorption of nutrients and create a more robust plant.

Grow Bags Allow for Greater Temperature Control

In the winter, the surface of the earth gets colder and colder. Even when the atmosphere warms up again, it can take a long time for the earth to warm up as well. It is like trying to warm up in the sun while lying on a block of ice.

Fortunately, grow bags allow you to separate plants fromthe cold earth. Planter bags are made of fabrics that allow for easy circulation of air. The end result is that the soilin grow bags warms up much more quickly than the soil in the ground.

That turns around and has beneficial effects on the health of your plants.

In contrast, pots tend to get very hot during the warmest months of the year. That can impair the growth of your plants. It can even cook your plants and damage them.

This goes double if they are exposed to direct sunlight. Unfortunately, you will probably want to expose them to direct sunlight so that your plants can get the sunshine that they need.

To avoid this problem, it is simpler to use something with easy air circulation that does not heat up too muchin the sun. Fabric plant pots provide both of these things!

Grow Bags Make Correct Watering Simple

Even today, watering plants is not an exact science. There are a lot of factors to consider and it is easy to underwateror overwater plants. However, grow bags allow you to easily sidestep many of the common difficulties connected to watering.

With grow bags, you can basically water them as much as you want. That means that you do not have to worry about underwatering anymore. But what about overwatering?

If you do add too much water to planter bags, the water will simply seep out. In other words, the grow bag will automatically regulate how much water each plant is exposed to.

Plus, the grow bag manages this without you having to worry about installing your own drainage holes. The nature of the fabric of grow bags issuch that it will allow water to disperse without needing any special holes cut into it. The elimination of excess water will also help prevent your bags and plants from developing mold or decay.

The end result is that you can achieve perfect watering without having to think as much about adding the exact right amount of water.

Although fabric plant pots allow you to avoid the problem of overwatering, they come with their own challenges. You will need to figure out a system to keep your grow bags constantly moist. That is because grow bags hold onto less water and thus need more constant watering.

One easy way to solve this problem is to set up a drip irrigation system. That way, you can provide a constant flow of water into your grow bags. Thatwould be a huge problem for other growing methods because it can lead to excess watering, but grow bags do not have this problem.

Of course, you can also simply water your grow bags frequently. During the hotter months of the year, that might include watering them multiple times per day.

Storing Garden Bags Is Easy

Grow bags are also very flexible. You do not have to keep them around taking up space when you are not using them. That can come in handy during the off-season.

When you're not using yourgrow bags, you can empty them and fold them up. Even huge numbers of grow bags will shrink to an almost unnoticeable volume when you store them away.

When the time comes for you to use yourgrow bagsagain, they will be waiting for you in excellent condition. You will be able to use them for many years to come.

Plants in Grow Bags Can Be Moved Around

It is easy to take plants out of grow bags. That means that growing a plant in a grow bag is not a commitment. You are not closing the door on other methods of growing.

That means that grow bags, in the unlikely case that they fail you, will fail in a very graceful way. They will failin a way that will not cost you. It will be easy for you to move your plants out of their grow bag and plant them elsewhere.

Alternatively, this feature can come in handy even if your grow bags are not failing you. You can deliberately design a system of planting where are you start with plantsin grow bags with the intention to move them into the ground later on.

The Right Uses for Grow Bags

As powerful a tool as grow bags are, they cannot do everything. They perform better for certain kinds of plants than others.

In general, you are looking for plants that do not have roots that need to grow too deeply. That means plants with shallow root structures, like carrots and lettuce, are a great choice for grow bags.

Alternatively, you can use grow bags to plant things like trees as well. Of course, you'll have to keep in mind that you will inevitably have to remove them from the grow bag at some point.

In fact, grow bags work very well for this purpose. When you transplant trees, theirroot structure is often negatively affected by having been confined during their infancy.

However, grow bags do not restrict root growth in the same way thatpots sometimes do. In other words, it is perfectly viable for you to start growing treesin grow bags with the intention to move them elsewhere later on.

Problems With Pots

Grow bags are not only better than pots when it comes to developing root structures of trees. Pots also negatively affect plants that grow in them in other ways.

For one thing, roots tend to grow in tight circles inside of pots. This unnatural structure has a lot of trouble adjusting to the earth when plants are removed. On top of that,it is an inefficient root structure.

This kind of circular root structure eats up a lot of resources from the plant without providing it with efficient nutrient uptake.

In fact, as roots continue to grow in circles they have a tendency to crowd out water and nutrients. If you have ever seen your plants start to wither while growing in pots, this is a strong hypothesis as to the cause.

Of course, you might imagine that something similar would happen withgrow bags. Whenroots reach the end of their space in a grow bag, should they not also continue to grow and take up more and more space and resources?

This is part of the genius of the grow bag. In a grow bag, the soil at the edges of the bag is drier than the soil in the center of the bag. That dryness is a signal to the plant inside that there is no point in growing beyond that point.

Pots do exactly the opposite. It is often at the bottom of the pot that the soil is most damp. That only exacerbates the root problems we discussed before.

Different Sizes of Garden Bags

There is a variety of grow bag sizes to consider. Depending on the size of plant you intend to grow, you will want to buy different sizes of grow bags.

Some of the smallest garden bags tend to hold about 2 gallons worth of soil. These smallgrow bags are appropriate for house flowers or other plants that you might keep in the home.

On the other end of the spectrum, there are grow bags that hold hundreds of gallons of volume. They are a good choice if you are growinga whole bed of plants. In between, there are grow bag sizes for many other plant options.

Grow bags can be a great choice to grow plants like lettuce, potatoes, eggplants, flowers, and leafy greens.

Other Plant Growing Tools

As great asgrow bags are, if you want the best performance out of them, you will probably want to combine them withsome other tools. As we discussed already, grow bags automatically control how much water they hold. In order to do this, they need to be able to release any excess water.

As a result, your grow bag may shed a significant quantity of water. You will probably want to put something beneathit to protect the surfaceit issitting on from that leaking water.

In general, you can use something like a tray to either hold the water or divert it elsewhere. Whatever you use, you should keep in mind the possibility of mold. The area beneath your grow bag may be constantly moist.

To avoid the development of mold, you should make sure to avoid putting anything underneath the grow bag that facilitates the growth of mold. Generally, that would meanyou should use things made out of stone, metal,or plastic.

Cleaning Your Bags

Once you finish growing a plantin its grow bag,you will need to wash your bag before using it again. Fortunately, it is simple to clean your grow bags. All you need is water and some kind of cleaning material like a little detergent.

Once your bags are clean, you may want to also soak them in a solution with vinegar in it. This can help restore your bags to complete freshness.

However, you want to make sure to carefully rinse your bags after cleaning. The chemicals in yourcleaning productswill not be good for future plants.

Some people are tempted to skip the cleaning process, but this can cause more problems than it is worth. Without proper cleaning, your bags can become a way for pathogens to travel between plants.

Use the Best Plant Growing Tools

Nature is often described as capricious. It can be difficult to accurately predict exactly what things you do will help a plant to grow well or not. When you are trying to manage all of the chaos of growing plants, it helps to make sure you have the best plant-growing tools to help you.

Are grow bags better than pots for tomatoes? ›

We advise growing your tomato plants in a tomato grow bag. This is because you can be sure that the soil conditions in the grow bag are ideal for the tomato plants. It is a good idea to cut some holes in the bottom of the grow-bag before planting as this provides drainage to prevent water-logging.

What are the benefits of grow bags? ›

Improved overall root health is one of the main grow bag advantages. As the plant roots become established in the bag, their sensitivity to heat and moisture naturally begin the process of "air pruning." Simply, this process allows the plant to create a more robust root system.

Why are plastic pots good for plants? ›

Retain Moisture

This means that the gardeners need to water the plants less when they are placed in plastic pots than when they are placed in clay pots to provide them with the same amount of moisture. This is particularly helpful for plants that require a constant supply of moisture.

What are the disadvantages of grow bags? ›

What are the Disadvantages of Using Grow Bags? They can dry out quickly, especially in hot weather, requiring more frequent watering. They may not be suitable for plants that require deep soil. Growbags can be easily punctured or torn, which can cause soil to spill out.

Is it healthy to grow vegetables in plastic containers? ›

Avoid containers that might contain toxic substances, e.g., treated wood or plastic buckets that may have stored chemicals. Satisfactory containers include plastic or fiber nursery pots; wooden bushel baskets; plastic, metal or wooden buckets; milk cartons - even plastic bags and recycled cardboard boxes.

Is a 5 gallon grow bag big enough for tomatoes? ›

For determinate tomato plants, a 5-gallon grow bag can be sufficient, while indeterminate tomato plants may require a larger 10-gallon grow bag or larger. To learn more about growing tomatoes, check out my guides: Why is My Tomato Plant Not Flowering?

Do tomato plants grow better in pots or in the ground? ›

In general, determinate tomatoes tend to do better in pots, so look for those. It's also possible to grow indeterminate tomatoes in containers, of course, as long as you provide enough support and soil volume.

What is the best container to grow vegetables in? ›

Plastic or clay pots, buckets, baskets, and wooden boxes are suitable for most vegetables. Plastic tubs and garbage barrels provide space for roots of rank-growing vegetables, such as cucumbers and tomatoes.

Are grow bags worth the money? ›

Trees grown in grow bags retain a better-formed root system when transplanted. Grow bags also prevent the encircling of roots that can choke a transplanted tree even as far out as several years after the initial transplant.

What do you put in the bottom of a grow bag? ›

Grow bags require well-draining soil that retains just enough moisture so the root mass will not dry out between waterings. Bagged products labeled as potting soil or container mix are ideal. Many potting soils contain peat moss but more and more mixes are now using coir (coconut fiber) instead.

Which type of grow bag is best? ›

Tarpaulin Grow Bags: Tarpaulin grow bags are made from durable polyethylene tarpaulin and can hold up to 18 gallons of soil. They are waterproof and reusable, making them a popular choice among gardeners.

What are the disadvantages of plastic pots? ›

Plastic pots also fail to release excess water, unlike ceramic pots, meaning plants are more likely to suffer from root rot and overwatering in plastic containers. Since plastic is non-permeable, the soil inside the planter cannot undergo its natural respiration cycle, which is not good for plants.

Is it bad to keep plants in plastic pots? ›

Plastic pots generally have thinner walls than their clay counterparts offering roots little if any insulation from temperature change. Black plastic can actually act as a solar collector, heating up the potting medium to plant damaging levels.

Do plants grow better in plastic or ceramic pots? ›

Plastic pots will retain moisture, so suit plants that like their soil damp. While unglazed ceramics, clay or terracotta are porous, so allow moisture to escape, so are good for desert-dwellers, or plants that prefer drier soil.

Do grow bags leach chemicals? ›

We at Epic Gardening trust our own Epic Grow Bags in either their lined or unlined versions, Root Pouch fabric grow bags, and GrassRoots fabric raised garden beds, both made of materials that don't leach into the soil or cause serious risks.

Do grow bags get moldy? ›

Mold proliferates in dark and damp environments. If you notice mold or fungus grew out your fabric bags, no need to worry. They can be removed and controlled. And most of them are even beneficial to plants.

Do plants grow well in plastic containers? ›

Plastic pots and containers are excellent choices for moisture loving plants, or for those of us who are less than regular with irrigation. They are made in every color of the rainbow and are usually made of inert material, often recycled.
