Plant Containers: Traditional Pots Vs. Grow Bags

Trying to figure out what type of container to use for your plants and medium? Well, you’re in luck! High Times Cultivation Editor Nico Escondido answers all of your grow questions in his weekly Nico’s Nuggets column, and today’s piece is all about traditional pots vs. grow bags.

The Question: Do You Recommend Traditonal Pots Or Grow Bags?

Thanks to you and High Times for years of great grow advice! Quick question on plant containers—do you recommend using traditional pots or grow bags to hold plants and medium? I know there are advantages to each type, but I am leaning towards bag culture. Any thoughts are appreciated and keep up the good work!

The Answer: The Advantages & Disadvantages Of Grow Bags

Thanks for reading and writing into the mailbag with a question.

Fabric pots are a top choice of growers, offering breathability and great drainage.

First, let’s explain to our readers a little bit about bag culture. Bag culture can be defined simply as growing a plant out of a bag, the same way one would utilize a plant container or a pot. But bag culture can also be defined as a method for extending or expanding the volume of media available to a plant’s root structure. In the latter scenario, an already-potted plant would be placed inside or on top of a bag filled with new grow media. The original pot would have holes in the bottom or several slits made in it so that the roots can grow down and out of the container into the extended medium of the bag. Because of these aspects, container bags are a preferred method for many greenhouse and indoor growers looking to expand root zone volume.

However, whereas bag culture can be an add-on in this way, this is not the only use for grow bags. Grow bags can be your initial, stand-alone container for individual plants or for multiple plant sites within a garden or hydroponic system.

There are many advantages of using bags as containers, including the fact that they are generally cheaper than pots—to the extent that they can be disposable with little monetary loss—though, they then have to be replaced, rather than being reused or recycled like pots can be.

Perhaps the biggest advantage, however, comes with fabric grow bags, which are more durable than plastic bags and much more breathable than plastic containers or bags. This is an especially important consideration as many new growers underestimate the importance of getting air—specifically, oxygen—to the root zone. While the green parts of the plants (above ground) breath in CO2, roots actually breath O2, which is integral to their growth and development. It is for this primary advantage that many commercial growers chose fabric grow bags, as the size of the root structure is directly proportional to the yield of the plant.

All of that being said, grow bags have a few drawbacks.

Sometimes drainage is less than ideal and additional holes need to be made at the bottom of the bags to aid in drainage. Additionally, grow bags may not be as durable as pots, lacking the structural strength that other more solid containers can provide. This can be especially true in heavy rain outdoors or in heavy-flow hydro systems. The larger bags can also be much more difficult to move because of the lack of sturdiness and the weaker fabric handles are prone to tearing with bags over 20 gallons. (Note: Fabric grow bags come in a variety of sizes ranging from 1-gallon to 200+ gallon bags for outdoor use.)

Huge fabric containers like this can grow large outdoor trees above ground.

Overall, for indoor table systems that require less mobility, fabric bags provide an excellent option for growers. The same can be said for large-scale outdoor operations where plants are grown to tree-size and will remain in a permanent location. But for systems that are high-impact or require frequent plant movement, sturdier containers might be the better option.

How to choose which to use.

These things are pretty cool, and they do come with a number of benefits when compared to a conventional pot. Right now, we want to take a look at some of the best grow bags for weed at the moment, so you can make the right purchase the first time.

What To Look For In Grow Bags For Weed

Before you go out and buy just any old grow bag for weed, there are a few important considerations that you should keep in mind.

Right now, we want to do a grow bag for weed buyer’s guide, so you know exactly what to look for.

1. Material Durability

Perhaps the most important thing to look for when buying grow bags for weed is how durable the material in question is, and what that material actually is.

For the purposes of growing weed, you definitely want nonwoven fabric bags, which has a lot to do with breathability and drainage, but also durability too.

Simply put, you need a bag that is durable enough to resist ripping or tearing, or flat out breaking, with many pounds of soil in them.

A bag that breaks with your pot plant inside of it is a bag that is going to kill your plants.

2. Size

Of course, something else you need to think about before making a purchase is how large of grow bags you need. Remember that weed plants of different sizes and at different stages of life require different size grow bags.

Seedlings will do fine with a 1 gallon bag, plants in their veg stage should have a bag between 2 and 4 gallons, and plants older than that, especially in the flowering stage, can do with bags or containers up to 11 or even 12 gallons.

3. Breathability

One reason why you want to look for a grow bag for weed made out of nonwoven fabric is so it is breathable. It’s always good when air can get to the roots and the soil, as it helps with proper moisture, humidity, and temperature control.

4. Drainage

Another great aspect of nonwoven fabric and other similar 420 grow bags is that they allow for drainage. These are not water tight, which means that water can pass through them.

Therefore, even if you give your pot plants too much water, the excess will be able to drain out, this potentially saving your weed plants from drowning.

5. Portability

Portability is something else you want to look for here. Now, once the grow bags pass a certain size and are full of soil, transporting them is going to be very hard, even with help. However, some sturdy handles for carrying can be a big help here.

6. Sturdy Walls

The other thing you want to look for in a good grow bag for weed is that the item in question has somewhat sturdy walls.

Simply put, it can get pretty annoying if you are trying to shovel soil into one of these things, only to have the walls of the bag constantly collapsing on you.

What is a grow bag for weed?

Grow bags for weed, or for other plants, are fabric bags that are used instead of solid pots or containers. They act just like pots or containers, but have softer walls, and they do come with some neat benefits to say the least.

What are the benefits of using a grow bag for weed?

There are indeed several benefits that come along with using grow bags for growing your weed, so let’s list these off real quick.

  • Grow bags, due to the fact that they are made of fabric, allow water to drain out. This can help stop your from overwatering your weed plants.
  • Grow bags, due to not being airtight, allow air to get to the soil and roots much more easily. This assists with proper temperature and humidity control of the soil.
  • Grow bags have the ability to keep weed plants warmer during cold times and cooler in excessive heat.
  • Grow bags tend to be quite portable, as they usually always come with convenient carry handles.
  • Grow bags encourage root pruning instead of root circling, which results in a much healthier, stronger, larger, and more capable plant root system.

Difference between using a grow bag and pots?

There are also certain differences to consider when deciding whether to use plastic containers or grow bags to grow your marijuana crop.

Here is a quick summary of using a grow bag vs pot;

  • Grow bags allow for much better drainage and moisture control than plastic containers.
  • Grow bags allow for much better aeration and ventilation for the soil, also better for temperature and humidity control.
  • Plastic containers usually do not have carrying handles, making them harder to transport than grow bags.
  • Plastic containers cannot be folded together or collapsed like grow bags can, thus making grow bags much better for tight storage conditions.
  • Roots growing in plastic containers often circle instead of prune, which is not exactly ideal.

What are the drawbacks of grow bags?

There are not many drawbacks to using grow bags for weed, but there are a couple that need mentioning.

  • Once grow bags, especially large ones, all full of soil, carry handles or not, they become unmovable.
  • Grow bags are made of fabric and if you get a low quality option, it may rip, tear, or break on you.
  • Grow bags can be a bit hard to work with due to having fairly soft walls. When putting soil in them, the walls may move around or collapse, which is not fun to deal with.

What Are The Best Size Grow Bags For Weed?

What size of container or grow bag you use for your marijuana plants should depend on the size and age of the marijuana plant in question. Below is a rough guide to container or bag sizing based on plant size and age.

  • Seedling – 1 gallon container or smaller
  • Early veg state – 2 to 4 gallons
